Urgent fisheries changes sought

چکیده

Europe's fishermen should stop catching North Sea cod and continue to avoid Bay of Biscay anchovies next year if the two species are to stand a chance of survival after years of chronic overfishing, scientists announced last month. Despite improvements in the numbers of northern hake, herring and mackerel, other species living in the northeast Atlantic need more time to rebuild stocks, the International Council for the Exploration of the Sea (ICES) said. European Commission fisheries experts use the ICES advice to calculate quotas for each commercial species for the following year. These are presented to EU ministers for approval. For North Sea cod, scientists have repeatedly said numbers are so low that the only solution is to ban fishing otherwise cod will disappear from these waters altogether. The Commission has usually rejected this idea for fear of wrecking communities that depend on fishing for a livelihood. Now, its focus is on a limited amount of fishing, strictly controlled. Last year, for example, ICES recommended a zero catch for North Sea cod for 2006. The Commission, with the EU ministers' backing, opted instead for a small quota of 26,500 tonnes. The main problem is that more than twice this amount is being caught as bycatch by fishermen seeking other species such as haddock, whiting, hake and plaice. Fishermen caught about 50,000 tonnes of cod last year and had to throw the dead fish back into the sea because it is classed as an illegal catch. The bycatches are difficult to avoid because cod are bigger than the other species and no method has been devised to catch the other fish without getting cod in the process. " There are still numerous stocks that are too heavily fished and stocks that are depleted " , ICES said in their statement. " Although there are slight differences in the actual condition of those southern (northeast Atlantic) stocks, ICES is advising for all southern cod stocks, with the exception of cod News focus Once again, scientists have warned that fishing for cod in the North Sea must stop if stocks are not to vanish, but there is some good news for northeast Atlantic fishermen. Nigel Williams reports. in the western Baltic, that there should be no catch in 2007. " They also raise concerns about sandeels. These are small eel-like fish that divide their time between swimming in dense shoals and lying buried …

Management Effectiveness of the World's Marine Fisheries

Ongoing declines in production of the world's fisheries may have serious ecological and socioeconomic consequences. As a result, a number of international efforts have sought to improve management and prevent overexploitation, while helping to maintain biodiversity and a sustainable food supply. Although these initiatives have received broad acceptance, the extent to which corrective measures h...

Expected rate of fisheries-induced evolution is slow.

Commercial fisheries exert high mortalities on the stocks they exploit, and the consequent selection pressure leads to fisheries-induced evolution of growth rate, age and size at maturation, and reproductive output. Productivity and yields may decline as a result, but little is known about the rate at which such changes are likely to occur. Fisheries-induced evolution of exploited populations h...

Rapid Fishery Assessment by Market Survey (RFAMS) – An Improved Rapid-Assessment Approach to Characterising Fish Landings in Developing Countries

The complex multi-gear, multi-species tropical fisheries in developing countries are poorly understood and characterising the landings from these fisheries is often impossible using conventional approaches. A rapid assessment method for characterising landings at fish markets, using an index of abundance and estimated weight within taxonomic groups, is described. This approach was developed for...

Harvest Strategies for an Ecosystem Approach to Fisheries Management in Western Mediterranean Demersal Fisheries

The serious overfishing of most Mediterranean stocks demands urgent reforms of the management measures aiming to guarantee the sustainability of resources, notably when compared with the improvement observed in other European areas. The new EU Common Fisheries Policy (CFP) constitutes an excellent opportunity to introduce the changes needed for such a reform. According to this CFP, all European...

Fisheries: hope or despair?

Recent work suggesting that fisheries depletions have turned the corner is misplaced because analysis was based largely on fisheries from better-managed developed-world fisheries. Some indicators of status show improvements in the minority of fisheries subjected to formal assessment. Other indicators, such as trophic level and catch time series, have been controversial. Nevertheless, several de...
