The Environmental Resource Management Department at the City of Cape Town needs your help:
We would like to try and get to whale carcasses well before they wash ashore on our coastline to deal with them more effectively and efficiently. As ocean users, if you come across a whale carcass floating anywhere in False Bay or from Cape Point north to Silwerstroom Strand we would be most grateful if you could call, whatsapp or sms 083 940 8143 (available 24/7) with an approximate location and time of sighting.
Please could I ask that you also forward/share this email to as many friends, colleagues or groups that you are aware of that use the ocean as we would like as large a network of people as possible that could report sightings.
Save that number in your cellphone contacts, and do your bit for beach safety and, hopefully, for the environment, by reporting sightings of deceased whales before they reach the beach.
Ideally (environmentally speaking) dead whales should be left out at sea to be scavenged upon by marine life and then sink to the bottom and return their nutrients to the ecosystem. Unfortunately the prevailing summer wind direction in Cape Town (south easterly) generally brings any such carcasses onto the beach in False Bay. This is a hazard to human safety because of the co-incident inshore presence of great white sharks during the summer months. A dead whale is a great feeding opportunity for sharks, and its accompanying oil slick will be evident from miles away, potentially bringing in more sharks to investigate. This is why the City wants the opportunity to deal with whale carcasses before they reach your local swimming beach.
It’s timely to remember that while some cetaceans die and end up on the beach because of reasons such as ship strikes, ingesting plastic or other pollutants, or acoustic disturbances related to human activity, some of these animals also die of natural causes or illness unrelated to man’s impact on earth. Many times, scientists will examine the dead animal and be able to state what most likely led to its demise. While it is distressing to see any dead animal, and particularly strange and discomfiting to see a whale on shore, this is not necessarily confirmation that “the ocean is dying” or that we are “killing False Bay.” Sometimes it’s just the circle of life. Dead whales were an important source of nutrients and building materials to Strandloper communities long before industrial shipping plied the world’s seas.
For more on what happens to whales that die at sea (hint: it’s magnificent), check out this video. For more on the collision of dead whales and the urban environment, there’s this post about a whale on the beach in Fish Hoek, this one about a whale on the road in Cape Town, and this one about a stranded whale in the United States.
But I digress. Save this phone number: 083 940 8143, and tell your ocean-loving paddler, surfer, sailor, boater and diver friends to do the same!
As a fourth and final (perhaps) installment to our guide to ocean-related MOOCs for the curious armchair scholar, here is a list of offerings from provider edX, including one about SHARKS. All about sharks!
I have only just discovered edX, so (unlike Coursera, Future Learn and Open2Study) I have not done any of these courses, and don’t speak from experience. The format looks similar to Coursera, so you can pay to get a “verified certificate” for the course, or just choose to audit it (like a Scientologist… bad joke, sorry), which doesn’t cost anything. Like Coursera, edX has an app so you can work (on certain mobile-friendly courses) on your iPad or Android tablet.
Two courses that are focused more specifically on climate and related science are:
Climate Change: The Sciencefrom the University of British Columbia in Canada doesn’t have any current or future sessions scheduled, but you can still view the course material. This course not only covers climate, science, but aims to equip you to evaluate climate science, and to communicate facts about the climate to others.
Published in 1989, this book is chiefly enlightening as a primer in how shark science and attitudes towards sharks have progressed in the last quarter century. Like Ainley and Klimley’s Great White Sharks, Sharks in Question is seriously dated. Far from making this a frustrating reading experience, I found it incredible how much more certain we are of so many things that the authors mention here in speculative terms.
It would seem from the forecast that it is a open and shut case of where to go and what to do this weekend. To be honest I am not too sure of the right thing to do! Both the Atlantic and False Bay are a colour that does not exactly inspire one to throw on a wetsuit.
The wind has blown more easterly and north easterly today than was expected, so it will not have done much for the visibility on either side. Sunday is out of the question as the forecast is for humping south easter, so that leaves Saturday.
I am launching from Hout Bay tomorrow afternoon and will have a better idea of whether it is clean enough for Saturday. The other option is shore diving at Long Beach. I reckon that there is about a strong chance that the water won’t be clean enough for any diving at all, though.
First up, let me refer those of you who are truly bloody-minded Christmas shoppers to the gift guides from previous years: 2010, 2011, 2012, 2013, 2014. This one draws heavily upon all of those, and you may safely skip the past editions unless you really want lashings of Christmas gifting cheer. I am tempted to say, as usual, that if you haven’t started thinking about this already, you’ve left it too late… But prove me wrong. (Plus, I’m publishing the gift guide a bit earlier than I usually do – you’ve got a month to get busy.)
For the person who has everything, or because you’re feeling grateful, consider a donation on behalf of your friend or loved one:
We’ve really got our money’s worth from our Wild Card this year. It has been used for multiple entries to Cape Point, for De Hoop, and for one or two other trips, and paid for itself in a few months. The full card is a bit pricey, but there’s a great alternative called My Green Card, that costs R110 and gives twelve entries to any of the paid sections of Table Mountain National Park (so, Cape Point, Boulders, Silvermine, Oudekraal, and a few braai areas). Read the fine print carefully though – if you use it up quickly, you have to wait for the 12 months to pass before you can purchase another one. But you can also share the 12 clips with friends, whereas a regular Wild Card is tied to your identity. You will have to go to the SANParks office in Tokai to get a My Green Card.
A DVD – either a movie, a series box set, or a documentary – is not a bad gift idea!
Clip Clop designs and prints beautiful tide charts for Cape Town and Durban and moon phase charts for the year. You can order online or usually find them at Exclusive Books.
If you take your own photos, you could print and frame a couple, create a photo book (Orms can help with this if you don’t know where to start), or experiment with stretched canvas prints if that’s your thing. A digital photo frame pre-loaded with underwater images is also a lovely gift for a diving friend.
Dive gear and useful stuff
Smaller items of gear such as cutting tools, masks, clips and other accessories won’t break the bank. Contact Tony for some ideas and suggestions as to what to get and where to find it.
You can order a WetSac online (seriously, check it out). Otherwise, a fabulous hooded towel that will be the envy of everyone at the dive site can be obtained from one of the surf shops (try Lifestyle Surf Shop and just walk in there with your head up like you don’t care you’re not a surfer) next to Primi Piatti at Muizenberg.
Otherwise, just think a little bit about what might be useful before or after a dive. Sunscreen, deep conditioner, cleansing shampoo, a mini dry bag, a beanie for cold days on the boat,
Here’s a quick read on shark repellents from Smithsonian.com. While it only takes a few paragraphs to explain the different attempts humans have made to avoid encountering sharks while using the ocean, the task of actually developing technology to do this is far more complex. Testing shark repellents is also ethically difficult – in the same way that it’s hard to test medications for use during pregnancy, as one could be causing harm to human subjects.
(It’s worth reading a bit about the Shark Shield device pictured above for more on testing. Testing the efficacy of stripy wetsuits, on the other hand, is almost impossible, and for this reason they can be almost impossibly lucrative – imagine a product where you don’t have to prove whether it works, and when it fails you can (a) throw up your hands and make an excuse along the lines of “it was a freak event”/”the guy must have been wearing it incorrectly” or (b) close the company and disappear.)
The “electronic fence” mentioned at the end of the article is the shark repellent cable that the KwaZulu Natal Sharks Board tested at Glencairn last summer. You can read more about that (also from Smithsonian.com) here.
This is the third post in a (long, sorry) series about the KwaZulu Natal Sharks Board. You can read the first post – in which I explain why I’m interested in the Sharks Board and what we know about it – here, and the follow up, describing its history and formal establishment, here.
To provide for the establishment of the KwaZulu-Natal Sharks Board; to determine the objectives, powers, duties and functions of the KwaZulu-Natal Sharks Board; to determine the manner in which the KwaZulu-Natal Sharks Board is to be managed, governed, staffed and financed; and to provide for matters incidental thereto.
The act applies to “the control of shark safety devices in the sea, sea shore and sea-bed of the Province.” It repeals the 1964 Natal Provincial Ordinance that established the Sharks Board and which I wrote about in the previous post in this series. It is broadly similar to the 1964 Provincial Ordinance in many respects, so I will primarily highlight the differences between the two pieces of legislation (as far as my amateur legal eagle brain can discern them). Want to read the entire 2008 act for yourself? Download it here.
Powers, duties and functions of the board (Section 5)
This section is divided into things the Board “must” do (5.1) and what it “may” do (5.2). In many respects, including the section number, it is very similar to the 1964 Provincial Ordinance.
The primary difference between what the Board is mandated to do by the 2008 act, but not by the 1964 Provincial Ordinance, is to
(b) endeavour to introduce schemes [bather protection gear] that
will reduce negative impact on all biodiversity; and
will enhance the survival of caught sharks and other marine animals;
(c) undertake research in order to –
consider and determine the feasibility of applying new or known methods of protection against shark attacks; and
determine any environmental impact arising from the implementation of any schemes or any methods of protection against shark attacks
There is nothing in the 1964 Provincial Ordinance suggesting any concern for the environmental impact of the Sharks Board’s activities. In this respect, the 2008 act is an improvement and perhaps reflective of increased environmental awareness that, some have contended, can be traced back to the “save the whales” campaigns of the 1980s.
The Board is to consider research and recommendations related to bather protection, and to take “reasonable steps” to raise awareness among bathers of the methods used to protect them, and of safety precautions that the bathers must adhere to. The Board is to make itself available to municipalities which are obliged to perform functions in connection with the ocean and the shore, inland waters, and emergency and lifesaving services. The Board may also assist municipalities with scientific research and studies.
A very important part of the act, which again differs from the 1964 Provincial Ordinance, states that the Sharks Board must,
in exercising its powers and performing its duties in terms of this Act –
promote biodiversity and ecological integrity by striving to avoid, mitigate and reduce any negative environmental impact;
do anything in its power to promote the sustainability of marine life;
endeavour to use all dead sharks and other marine animals caught by the schemes implemented in terms of this Act, for scientific research
The Board is to, “where possible, release all live marine animals, including sharks, caught or affected by” the gear, and to keep accurate records of these animals.
The Board may liaise with any relevant institution regarding environmental matters, tourism and economic development in KZN. The Board may consult with any organ of state, organisation, institution, body or committee about any matter related to bather protection.
There are sections permitting the Board to enter into agreements, purchase/lease/hire equipment and property, dispose of worn out or useless equipment (with certain caveats). The Board may also acquire and dispose of interests in companies, partnerships and the like, subject to MEC approval, as well as enter into joint ventures. It may also register patents and trademarks, and buy and sell these at will. This may be important in the future, if the Sharks Board develops a non-lethal (or less lethal) novel method of shark mitigation.
The Board is permitted to “raise funds by any lawful means” including via acceptance of donations, bequests and sponsorships. Funds may also be in the form of “revenue derived from tourism levies and the use of permits”, and similar sources. The Board is permitted to charge fees for provision of services, as well as for “entrance into an exhibition or display of shark control resources by the Board”. This it does do.
Powers of the Sharks Board (Section 6)
This section enables the Board to develop and maintain bather protection equipment “as it deems necessary and practicable” for the safety of bathers. As in the 1964 Provincial Ordinance, the Board is empowered to go over the head of a municipality with which it cannot reach an agreement regarding the nature of the equipment to be used, or the basis on which the municipality is to remunerate the Board.
Composition, Functioning and CEO of the Board (Sections 7-21)
These sections beef up the content of the 1964 Provincial Ordinance but don’t really contain anything particularly interesting. They describe the members of the board, and what qualifications and experience they must collectively embody (someone on the Board must know about marine conservation, someone must be from the tourism sector, someone from a conservation NGO, and so on). The frequency of meetings and procedures for the board’s functioning appear in these sections, too.
Funding of the Sharks Board and Financial Matters (Sections 22-25)
This section is interesting, particularly in light of the information in this link to the UN Food and Agriculture Organisation website. Until at least 1999, and probably a few years after that, the Sharks Board was supplementing its funding through the sale of curios manufactured from shark products. I see this is as a classic example of moral hazard, although I may be stretching the definition a little! (The usual example given of a moral hazard would be if an insurance company let you take out fire insurance on your neighbour’s house. This might create an incentive, if you didn’t have strong moral fibre, for you to burn down his property and collect an insurance payout. Here, substitute “sell shark products” for “take out fire insurance”, and “catch more sharks” for “burn down his property” to see what position this places the Sharks Board in.)
According to the 2008 act, the Sharks Board obtains funding from the Provincial Legislature, donations, income (for example from tours of its facility and curio sales), interest on investments by the Board, and fees received for provision of shark control services. It is explicitly stated that souvenirs and curios sold by the Board may “not contain any dead sharks or other marine animals, or part thereof, caught by the schemes implemented in terms of this Act.”
This ensures that the Sharks Board is not given an incentive (see how I avoided using the word “incentivised”?) to catch and kill marine life and removes a potential conflict of interest, between preserving marine life and making money from selling dead marine life. That is why this proposal met with such an outcry.
Dissolving the Sharks Board
Sections 26-34 cover general provisions. Section 29 states that “the Board may only be dissolved in terms of an Act of the Provincial Legislature.” Section 35 repeals the Natal Sharks Board Ordinance (No. 10 of 1964). Section 36 provides continuity between the Board established under that Ordinance, and by this Act. Section 37 states the short name of this act, which is the KwaZulu-Natal Sharks Board Act, 2008.
Thank you for following along with this exercise in understanding the Sharks Board, its structure, and its obligations. One of the most important things that I have learned from diving (ahem) into the legislation and annual reports of the KwaZulu Natal Sharks Board is that it is a legally constituted body, and for its function to change appreciably, or for it to cease operation (which would probably compromise bather safety in KwaZulu Natal), it would have to be legally dissolved. This fact should inform the approach that we take as concerned ocean people when it comes to directing energy towards protests, engagement with interested and affected parties, and other actions to reduce the shark fishing activity that the Sharks Board currently engages in.
My own half-formed view is that it may be productive to try to find ways to support the Sharks Board in its efforts to develop non-lethal shark repellents. An example of how you could be helpful in this regard would be writing to the City of Cape Town and DAFF in support of using Fish Hoek beach as the location for any future trials of the Sharks Board’s electrical shark repellent cable. Fish Hoek beach is far sharkier than Glencairn, and would provide conclusive results regarding the effectiveness of the cable far quicker than Glencairn has (the Glencairn test was largely inconclusive because no white sharks came by). It was excluded as a trial location because DAFF was concerned that the catches of the beach seine (trek) fishermen who operate in the area would be affected by the cable.
Another idea for how you can make a difference would be to engage directly, in a mature manner, with municipalities along the KZN coast to encourage them to reduce their dependence on Sharks Board gear. An example of such an engagement by Sharklife, which was reasoned, practical, data-driven and ultimately a success (and for which many will claim credit) can be found here. These things take time, effort and persistence, and results are incremental rather than spectacularly immediate.
If you have any other ideas as to how a citizen activist – thinking like David Helvarg – could have an impact here, I’d love to hear them.
(A different question, which each person must answer for themselves, is whether this is the area in which one can have the most impact, as a local activist – is it the best use of your energy and ability to make a difference for the ocean? You should read Saved By the Sea, or at least look up the Blue Frontier Campaign, which is explained a bit better on its wikipedia page than on its website, if this seems like a stupid thing to ask.)
With increased use of Durban and South Coast beaches after the Second World War – numbers of swimmers and surfers increased exponentially – the incidence of shark attacks rose to the extent that, already in the 1940s, newspaper articles discussed possible “anti-shark” measures. Four shark attacks occurred in December 1957 (known as “Black December” by Durbanites), and by April 1958 a further three had occurred. Five of the seven attacks were fatal, and they occurred at the beach during summer – a crowded, public space. In the same way that the early 21st century shark incidents at Fish Hoek beach could be described as a “public trauma”, these attacks traumatised both Durban locals and holidaymakers from South Africa’s inland provinces.
The history of anti-shark measures and shark research in KwaZulu Natal is traced in detail in this Masters thesis by Melissa van Oordt, which, if you have an interest in the subject, I recommend you download and read. Van Oordt argues that myths about sharks, developed in the minds of the public following shark bite incidents along the Natal coast and fuelled by the media, drove the formation of the Sharks Board and the installation of the bather safety gear along the KZN coast. Sharks were characterised as “rogue”, “man eater” and “brute” – and the language used to describe them shaped the response.
The first nets were deployed in 1952 off Durban’s beaches by an organisation called the Durban Beach Committee, following the lead of New South Wales in Australia (nets were set there in 1937). After 1964 the beaches on the South Coast were also netted. Other measures, such as helicopter patrols and setting off depth charges, were experimented with, but were found to be ineffective, too expensive and/or too destructive to other marine life.
(It is also worth mentioning that already in 1958 measures such as electrical and chemical shark repellents and mechanical barriers were under discussion. In 1968 -69 development of an electrical shark barrier had made such good progress that full-scale testing at a Natal beach was anticipated “in the near future” [van Oordt page 113]. It has taken over half a century for these ideas to begin to come to fruition, and there is still some way to go.)
Establishment of the Natal Anti-Shark Measures Board
In 1964 the Natal Anti-Shark Measures Board was legally constituted by Natal Provincial Ordinance No. 10, which is freely available from the National Library (this is where I got my copy). The board was formed as a body corporate, which meant among other things that it could “sue and be sued.” Its functions and duties included:
taking advice from, considering findings of, consulting with and calling upon scientific and technical research bodies or individuals on the subject of “bather protection against shark attacks”; and
considering existing and proposed bather protection schemes to determine their effectiveness, and improving or supplementing them where necessary.
Local government authorities would provide the Anti-Shark Measures Board with estimated expenditure figures for anti-shark measures, as well as plans for any “actual or proposed anti-shark scheme” to which the expenditure figures related. The Sharks Board would vet the schemes proposed by the municipalities, suggest improvements, and approve expenditure for the anti-shark measures. Approved bather protection schemes would be subsidised by the board by at least ten percent of the municipal expenditure.
The Sharks Board was also authorised in the 1964 ordinance to install bather protection schemes on parts of the coast that were not under the jurisdiction of a local authority, and where agreement could not be reached with a local authority regarding the nature of a bather protection scheme, the board was able to go ahead and install shark safety gear, and recover some or all of the costs of doing so from the municipality concerned. This is quite a significant power – I would be curious to know whether it has ever been exercised.
The Sharks Board’s source of funding was declared to be “donations and bequests received by it”, as well as funds “appropriated by the Provincial Council for the purpose” – in other words, funds distributed to the Sharks Board by the Natal provincial government.
The Sharks Board was thus established legally, with most of its funding coming from the Natal provincial government. It had fairly broad powers in terms of installing bather protection gear along the Natal coastline, and no particular prohibitions on what it could and could not engage in.
Van Oordt describes how, in the 1980s, the Sharks Board began releasing live sharks caught in the nets, reflecting a changing view of sharks, and the environment in general, that had begun to emerge among scientists and the general public. In 1991, in a further concrete indication of changing attitudes to sharks, great white sharks were legally protected in South African waters, making it illegal to catch or kill them unless authorised by the Department of Environmental Affairs.
Until fairly recently (at least until 1998 and possibly 2003) it was the case that:
The NSB sells certain shark products to defray expenses. Income from such sales is small relative to total expenditures. Products sold from the Board’s curio shop include shark teeth – sold either loose or with a jump ring for attachment to a jewellery chain – and entire jaw preparations. In addition, dried fins are stockpiled and sold, usually annually. Initially sales of fins were to local exporters by a tender process but the NSB is now investigating direct export. Fins and teeth from great white sharks Carcharodon carcharias are not sold because the species is locally protected. The meat from netted sharks is generally not sufficiently fresh for human consumption. Experimental inclusion of the meat in animal feed has been unsuccessful. [Source]
As we will see in the following post, such sales of shark products were forbidden by an act of 2008 which superseded the 1964 ordinance that established the Sharks Board. This, too, could be an indication of changing attitudes towards sharks and shark conservation in South Africa.
The KwaZulu-Natal Sharks Board (KZNSB) is frequently discussed, and often vilified, among ocean-loving South Africans. Rumour abounds; whole websites, devoted entirely to inaccurate speculation, exist. When the Sharks Board tested a shark repellent cable in the waters of Cape Town, starting in late 2014, I was frustrated by my lack of knowledge about how the KZNSB is structured, who funds it, and who mandates it to do what it does. Understanding these aspects of the Sharks Board’s operations could surely assist with moving towards a future where, if the Sharks Board still exists, it uses primarily non-lethal shark mitigation measures. (Unfortunately, no scalable measures suitable for the KZN coastline exist yet.)
Many people are concerned by declining shark populations, but many people are also concerned about their safety when they go for a surf or a swim. These groups overlap, but not wholly. The ideal shark mitigation measure combines bather safety with shark conservation. Examples exist, but they are rare. Cape Town’s Shark Spotters do an excellent job of striking a balance between safety and conservation, but what many commentators – who advocate deploying shark spotters at sharky beaches the world over – do not admit (or realise) is that Shark Spotters works because in Cape Town we have elevated ground close to the ocean, and great white sharks that spend a lot of time swimming on the surface when they are inshore. Take away one of those two crucial elements, and an already tricky job becomes exponentially more challenging.
What the KZNSB does
The KwaZulu-Natal Sharks Board protects bathers in KZN with what are essentially fishing measures: 23.7 kilometres of gill nets and 79 drum lines are installed along 38 beaches in the province. These nets and drum lines catch sharks and other marine creatures. The nets are checked by Sharks Board employees, and live sharks (and other animals) are released. Sharks that don’t survive are used for a variety of research – the Southern African Shark and Ray Symposium in September featured at least six presentations based on samples and data obtained from the Sharks Board.
While it is legal (read carefully – I am not condoning the practice) for the Sharks Board to remove sharks from the ocean, it is no longer considered ethical for scientists who wish to study sharks to use lethal sampling methods – to go out and shoot a shark so that they can study its stomach contents, for example. This practice would also be illegal for sharks that are protected, such as great whites in South Africa (the Sharks Board is permitted to catch them, however). There is much about shark biology that can be learned from a dead shark – for example an understanding of its reproductive systems, its position in the food web, its diet, samples to determine genetic inter-relatedness of populations, and age and growth data can all be gleaned from a necropsy. Perversely, much of the scientific output obtained from these avenues of research is useful for shark conservation and management planning. This is why, when a shark washes up dead or is accidentally caught in the Western Cape, scientists are keen to learn as much as possible from a dissection.
The website of the KZNSB describes a number of measures that the Sharks Board has taken to reduce its catches of species other than sharks. In particular, entanglement of cetaceans such as dolphins and baby whales is (apart from the environmental impact and sheer wastefulness) a highly emotive issue and a public relations nightmare for the Sharks Board and they actively seek to mitigate this kind of by-catch. In 2014, only about 40% of “non-target species” caught in the nets were released alive (no whales were killed).
How does the KSNZB, an organisation whose activities have a potentially significant impact on shark populations, fit in with broader initiatives to take better care of South Africa’s sharks?
Shark Biodiversity Management Plan
In March of this year, South Africa’s Shark Biodiversity Management Plan was published by the Department of Environmental Affairs. It is a remarkable document and represents the culmination (and the beginning) of a great deal of work by a great many people. It deserves (and will hopefully get) a more detailed examination than this, but I have isolated the sections that pertain to the KZNSB because they shed light on how the KZNSB is characterised by the government, and on the pressures it is under.
In the South African Shark Biodiversity Management Plan on pages 13-14, the KZNSB is listed as an organisation that “actively support[s] the management and conservation of sharks”.
On page 29 the KZNSB is listed as a responsible party under part of the Biodiversity Management Action Plan, with things to do in order to effect conservation of sharks in South African waters. The KZNSB is to “research and implement methods mitigating by-catch (e.g. drum lines)”, high priority, to start within a year of March 2015 and to be completed within five years; and to “investigate alternatives to shark fishing systems”, with the same priority and timeline. We know that the KZNSB has been actively testing alternatives to nets and drum lines – their shark repellent cable test in Cape Town’s waters is a case in point.
Page 25 states that the KZNSB is “cognisant of the need to minimise the environmental impact on biodiversity, while striving to improve/evaluate methods that have a lower environmental cost.”
The piece of legislation (more on this later) that establishes the Sharks Board mandates the sharks board to consider alternative mitigation methods, to reduce environmental impact, and “enhance the survival of caught sharks and other marine animals.” The particular section of the act defining the Sharks Board’s mandate is quoted in the KZNSB 2014 Annual Report (pdf). The report also suggests (on page 23) that pressure from environmental groups is providing an additional impetus to the development of other bather protection strategies.
All this underscores the fact that the Sharks Board is expected to find alternative (non-lethal) shark mitigation methods, and is legally mandated to attempt to do so.
National Plan of Action for Sharks
The South African National Plan of Action for Sharks (NPOA) sets goals for the implementation of measures towards ecologically and economically sustainable shark fisheries, and aims to improve conservation and management of sharks found in South African waters. The KZNSB is mentioned on page 13 of the NPOA document, as a “directed shark fishery”, with a reminder that
In terms of the provincial KwaZulu-Natal Sharks Board Act, 2008 (Act 5 of 2008), the KZNSB is required to endeavour to introduce schemes that will reduce negative impact on all biodiversity. In addressing biodiversity issues the KZNSB has already reduced the number of nets, introduced drum lines, and has removed shark fishing gear during the annual winter sardine run.
The Sharks Board is thus recognised in its capacity as a shark fishery in the NPOA document and mandated to conduct itself as described above (a broad requirement), as well as a potentially important player in the conservation of South Africa’s sharks in the Shark Biodiversity Management Plan.
On page 23 of the KZNSB 2014 Annual Report (pdf), it is noted that one of the “challenges” facing the Sharks Board is that “other organisations are also developing environmentally-sensitive shark repellent technologies which may compete with that being developed by KZNSB.” I don’t know how exactly to read this, but it seems that the Sharks Board is concerned that if another entity were to develop a shark mitigation technology that doesn’t kill sharks, this would be a bad thing for the KZNSB. I can only infer that this refers either to potential lost profits from licencing a KZNSB-developed product, or to costs that the KZNSB would potentially incur should they be forced to implement an environmentally friendly shark mitigation technolgy developed by someone else.
Either way, it establishes a strong financial motive – at least at top management level – behind efforts to develop non-lethal shark repellent strategies. While this impurity of motive may not warm your environmentalist’s heart, a quick scan of the KZNSB annual reports should convince you that it is more analogous to a corporation than to an environmental organisation or charity and it should be expected to operate as such. Individual motivations of staff and researchers within the Sharks Board may well be related to shark conservation, but the organisation as a whole must remain financially viable.
A news report in November 2014, to which I have not been able to find a follow up, quoted the KZNSB CEO as suggesting that the Sharks Board be able to sell shark meat, fins, and other curios manufactured from shark products (such as teeth) in order to raise funds. The difficulty with this suggestion – which is expressly forbidden in the 2008 KwaZulu Natal Sharks Board Act – is that it could create an incentive not to release live sharks caught in the nets, or for the Sharks Board to deliberately harvest sharks in order to turn a profit.
What I hope I have provided is an overview of some facts about the Sharks Board that can be obtained from publicly available sources, all of which I have linked to in the text. I will do two follow up posts in which I will look at the origins of the Sharks Board and the legislation (from 1964 and 2008) that gives it its mandate and legal structure. Do ways exist in which concerned, rational, ocean loving citizens can work to create a future in which the South African coastline is free of nets and drum lines? What kind of things should we support in order to make the whole of South Africa – and not just Cape Town – a world leader in shark mitigation techniques?
At the very least an understanding of the entity that is the Sharks Board may assist in determining whether a particular form of activism or protest about its activities is likely to have any effect. And if a form of protest is not going to be ineffective, regardless of the passion and enthusiasm behind it, those energies could be better spent on one of the many other threats to the marine environment.
Saturday and/or Sunday: Early launches from OPBC (Saturday) / Simon’s Town jetty (Sunday) depending on weather and demand
Last Saturday we launched the boat in Hout Bay for a team of researchers to deploy and retrieve three of the acoustic tracking receivers that listen for tagged sharks and other animals along South Africa’s coastline, providing information about their movements to scientists. The receivers are part the Acoustic Tracking Array Program (ATAP), and you can read more about how it works here.
We launched from Hout Bay again on Tuesday, and the 3 metre swell could be felt at 30 metres on Tafelberg Reef. The visibility was OK, but the water was really cold.
Weekend dive plans
False Bay looks a little messy right now and tomorrow’s wind is not going to help. Today and tomorrow the swell is around 3 metres and goes southerly. Both days of the weekend have strange weather patterns in the forecast.
I reckon Saturday would be best at OPBC and Sunday would be best for False Bay. Wind speed builds mid-morning so either way you are looking at a really early start – and by that I mean launched by 7.00 am. Both days lend themselves to double tanking to avoid the wind.
A 7.00 am launch is not everyone’s cup of tea so I suggest we decide where to go based on who is diving. You can text, Whatsapp, facebook message, email or carrier pigeon your desires to my door if diving is on your mind.
