WWF and krill - Conservation gone wrong

Updated Friday 19th October 2012

The Wikipedia entry for the World Wide Fund for Nature (WWF) states that 'WWF is an international non-governmental organization working on issues regarding the conservation, research and restoration of the environment'.

No surprises there then, just as you imagined, WWF working hard to protect nature, wildlife and the environment. Commercial exploitation would be the last thing you'd think WWF would be involved with. And that's where you'd be wrong.

Since 2009 WWF Norway have been in partnership with Aker Biomarine, a Norwegian company that runs the largest krill fishery in the Antarctic. Aker Biomarine pays $178,000 annually for the privilege of putting the WWF logo on its products. In October 2012 WWF Australia signed a new partnership deal, this time with Australian fish and krill oil producer Blackmores. WWF have not yet disclosed how much this new partnership is worth.

Some might think that it is an oxymoron for a conservation organisation to be raising funds from entering into partnerships with companies that rely on the commercial exploitation of wild species to make their products. After all krill are a keystone species and numerous animals rely on them for food. There is also serious doubt about what the environmental impact a krill fishery would have in the Antarctic.

Even WWF are worried about krill.

In a report entitled 'Blue Whales - Under Threat' WWF stated that 'the problem of declining krill threatens most of the Antarctic food chain, but it is especially serious for the blue whales because there are so few of them'. Stuart Chapman of WWF goes further saying 'when you get this kind of warning shot that indicates something is going terribly wrong in the Antarctic, we need to sound the alarm.'

You'd expect consistency of communication from one of the world's largest conservation organisations, but WWF's apparent confusion over the krill issue is worrying. Either that or WWF are just mere opportunists who garner funds from leaping on the nearest bandwagon?

Krill exploitation is truly scraping the bottom of the barrel. It is the final frontier of marine exploitation, and a frontier that shouldn't be crossed. The Antarctic krill fishery is in its infancy and could still be nipped in the bud. WWF's endorsement not only encourages the expansion of the fishery, it lends respectability to the commercial exploitation of the whole Antarctic region.

If you think that WWF have made an error by endorsing the Antarctic krill fishery, please sign this petition.

Is the RSPB failing seabirds?

In recent reports the RSPB claim that climate change is altering the availability of sandeels and causing seabirds such as kittiwakes, Arctic terns and Arctic skuas to fail to breed successfully.

The evidence seems to be much stronger for overfishing to be the cause of these failures, and the RSPB, by avoiding the elephant in the room, may be damaging the long-term recovery plan for seabirds.

In most RSPB reports there is often no mention that overfishing is also a likely cause. It makes you wonder whether there are political motives for this blinkered stance? An analogy would be like blaming climate change instead of industrialised intensive farming since the 1950's for the decline in British birds.

The sandeel fishery has now become by far the biggest single-species fishery in the North Sea, with landings accounting for one-third of all fish landed. The vast majority of this catch is landed and processed in Denmark. Such fundamental changes in the fabric of the marine ecosystem are what ecologists refer to as 'fishing down the food web'.

Since 1977, total yearly North Sea sandeel catches have fluctuated around 600,000-800,000 tonnes, but since 2003 catches have crashed dramatically to between 200,000-300,000 tonnes. The collapse of the fishery was particularly severe in the Norwegian economical zone with a 95% reduction in landings in 2005.

Many scientists and ecologists believe that the recent disastrous breeding seasons for many of Europe's seabird colonies can be directly linked to the industrial fishing of sandeels in the North Sea.

As early as 1997, two respected Danish fisheries scientists - Henrik Gislason and Eskild Kirkegaard - were highly critical of the North Sea sandeel fishery, and they concluded that "it cannot be ruled out that (sandeel) fishing could adversely effect (sic) the breeding success of the birds. It would therefore be precautionary to close areas to fishing until more is known about sandeel stock structure and interactions between sandeels and seabirds".

And a report published by the International Council for Exploration of the Seas (ICES) suggests that "the amount of industrial fish species taken by fishermen in the North Sea appears to leave little for seabirds and marine mammals".

The UK has some of the most significant seabird populations in the world, and discovering the exact cause of their decline is essential if we want to implement an effective recovery plan. If the RSPB have got the diagnosis wrong, then we will probably end up with a dead patient.

Future ocean

If you had travelled the world in 1812 the natural wonders seen on earth would be jaw-dropping. Plains full of grazing animals and attendant predators, huge forests covering much of the land and a sky full of birds. Wildlife in such abundance that it is hard to imagine now.

Over the next two centuries human encroachment chopped down the forests, ploughed up the plains and hunted the animals to a fraction of their pristine numbers. Some animals thrived under these new conditions, but 95% did not.

At the beginning of the 20th century, shortly before destruction was absolute, some enlightened people decided to act and national parks like Kruger, Yellowstone, and Etosha were formed.

Unless we learn from our terrestrial mistakes, what happened on the land can give us an accurate glimpse of what is in store for the world's ocean.

Ultimately we will deplete the vast majority of the ocean through overfishing, leaving only small pockets of biodiversity - effectively the national parks of the sea. Farmed animals will replace wildlife, with aquaculture cages ringing our coasts and filling the open-ocean in their thousands. Wind farms and tidal generators will festoon the waters that once teemed with life, whilst new technology and ice-free conditions will open up once inaccessible regions to the mining, energy and shipping industries.

It isn't too late though. We still have an opportunity to do for the ocean what we failed to do for the land - protect the ecosystem holistically. There is still enough marine life left to repopulate the entire ocean, but the protection must be interconnected. This is where we failed so miserably on land by creating small, isolated nature reserves that are more akin to zoos than places where nature can thrive.

If we protect 30% or more of the world's ocean from all destructive activity now, with a network of carefully chosen marine reserves, the resultant proliferation of marine life could allow for enough sustainable exploitation to feed a rapidly growing human population. But if we act too slowly, or do not do enough, the future ocean may become as devoid of biodiversity as the vast majority of the land has become.
