The outlook for endangered albatross species has dramatically improved, thanks to the success of an international conservation programme implemented by the RSPB and Birdlife International.
The Albatross Task Force (ATF) was established in 2006 in order to reduce the number of accidental albatross deaths caused by long-line fishing. At the time, it was estimated that one bird was killed every five minutes from long line fishing, and 19 of the 22 albatross species were under threat from extinction.
The birds dying because they were taking bait from fishing lines fed into the sea from boats fishing for tuna or swordfish. Once they swallowed the bait, they would become caught on the hook, dragged underwater and drown.
Specialist instructors from the ATF went out with fishermen and taught them techniques that would stop the birds becoming entangled. They were encouraged to fish at night, weight their lines and attach streamers the back of vessels to scare the birds away. Government legislation also played its part by stipulating that no more than 25 birds could be caught as "by-catch" during trips.
The programme has been heralded as a resounding success, and has reduced deaths by up to 85% in some locations.
Dr Ross Wanless, coordinator of the Birdlife programme in Africa, said: "Changing entrenched attitudes and practices is a slow process, but the ATF has shown that by working with government and industry, change is possible."
Whilst the 19 species are not freed from the threat of extinction yet- many are still snagged by trawlers, breeding is slow and habitats are endangered - the campaign is likely to have made a remarkable impact on their population stability and its success cannot be understated.

Questions Over Future of Fast Food Fish
As popular white fish species such as cod, face fisheries collapse, pollock has increasingly been an essential alternative. For instance the kid's favourite, Fish Fingers, now increasingly consist of pollock rather than cod, as do McDonald's 'Filet-o-Fish.'
Perhaps the pollock's newly received endangered status has been brought about by increased corporate-consumer demand.
Recently the US National Marine Fisheries Service advised an 18 per cent reduction in next year's catch from the pollock's stronghold in the eastern Bering Sea. However given that advice about the North Atlantic Cod stocks were not heeded, many believe greater reductions are needed.
Greenpeace's oceans campaign director, John Hocevar has been vocal about the need to reduce pollock fishing in order to prevent total collapse, suspecting that "we are on the cusp of one of the largest fishery collapses in history."
Many scientists including Hocevar believe that the pollock's immense decline could be the reason that stellar sea lion's - a major predator of pollock - are faring so badly. Their numbers have tumbled by 80 per cent since the 1970s.
Once again, the imperative to diversity fish tastes at home and abroad has been highlighted, to allow imperilled fish stocks to recover.

Larger Fish Produce Hardier Offspring
Research published in the Royal Society's Biology Letters journal suggests that fisheries management must consider population demography.
Modeling the life history demographics of 25 different marine fish species, Canadian scientists have found that larger, older female fish produce tougher offspring than their younger counterparts.
In efforts to make fisheries more sustainable, conserving the elder female fish could help sustain populations. Currently the findings of the research are out of sync with real-life fisheries practice, where the largest fish are sought. Overfishing results from this practice because of the two-fold effect of removing the best breeders, and subsequently reducing the rate of recruitment in the local population.
It is suggested that by enforcing size regulations, altering the size of fishing gear and how it's used could protect the bigger older individuals. The practicality of implementing these measures on the ground are not explored explicitly however, and targeting large female fish within populations could be very difficult to implement.
Do blog readers believe that European fisheries practices are sustainable? Does the Common Fisheries Policy need re-evaluating?

Bluefin Tuna Under Threat from Short-Sighted EU Policy
It seems as though the Government-Industrial complex has overcome sensibilities in a move by the International Commission for the Conservation of Atlantic Tunas (ICCAT), calling to maintain fishing levels of bluefin tuna Thunnus thynnus 50% above scientists' recommendations.
ICCAT members decided to permit a take of 22,000 tonnes per year (Total Allowable Catch), despite ICCAT scientists setting a quota of 15,000 tonnes (TAC). The members voted on the higher quota despite warnings by scientists that fisheries would collapse if their advice was not heeded. The ICCAT members' target does not even take into consideration the additional 30% of take that illegal fishing contributes.
Some European countries have independently expressed concern over bluefin stocks. Spain, which consume the most tuna of any European country, called for a suspension of the fishery, whilst Italy have opted for a total moratorium.
It is thought that conservation groups may now engage the Convention of International Trade of Endangered Species (CITES), in order to enforce trade control over the bluefin tuna trade.
Europeans, particularly the British, have a tendency to favour very few fish species over the relative diversity of fish available on the market. There are many decent alternatives to popular choices such as Atlantic cod and bigeye tuna (stocks of both are perilously depleted), its simply a matter of educating the public, and where possible your colleagues.
The Marine Conservation Society has provided a comprehensive sustainable fish guide, and a pocket-sized version is available from their fish online website.

Avoiding Imminent North Sea Cod Extinction
Cod is historically one of the most popular commercial fish species in the UK, not to mention popular across the European continent. Because of this, major commercial fisheries have been forced to close, and existing fisheries may also soon face closure.
Exacerbated by the mismatch in timing of their young's main food source, the copepod, caused by predicted warming events, Cod face an uncertain future.
If cod populations disappear completely, it is likely that 'trophic cascade' events could occur, i.e. the food chain within the broader community could be severely disrupted, as happened when the Canadian cod stocks collapsed.
A recent review paper published in Biology Letters suggests that fisheries management should be at the species-fishery scale, rather than a broad species-specific approach to management. The motivations for the author's suggestion lie in the considerable variability in genetic make-up and spawning aggregations between different cod populations, and the potential for small meta-populations to crash without being detected, since these are amalgamated with the whole population. Therefore data collection should be accurate and well-timed for effective management.
Targeted conservation measures are recommended to policy-makers where appropriate, however the socio-economic consequences of any decisions made must be given serious consideration.

Fisheries 2027
Defra wants to know what priorities should drive fisheries policy until 2027. Defra's draft vision is to maximise the long-term economic benefits of commercial and recreation fisheries, within environmental and social constraints. It highlights a number of possible trade-offs between economic, social and environmental considerations. For example, should fishing effort be curtailed to ensure that some fish stocks don't collapse? Scientists are expected to provide the best possible science, involve stakeholders in data collection and communicate their findings to stakeholders. The BES will be responding to this consultation by 26 April 2007.
