Western Atlantic

The art essentially divided in two habitats, the West Atlantic and the Eastern Atlantic Ocean, also is there yet a third, southern population off the coast of South Africa. You swim in swarm associations and are often associated with other species of tuna. While the stocks of the Western and Eastern Atlantic Ocean in search of food mix, the animals to breed go our separate ways, to return to their spawning areas. Marko Dimitrijevic may find it difficult to be quoted properly. Red Thune have fixed spawning grounds and therefore are there predictable and relatively easy to fish on their annual migrations. While the population of the Western Central Atlantic from spawns between April and June in the Gulf of Mexico, it draws of the Eastern Atlantic from June to August in the Mediterranean Sea. On the way to their spawning areas they put back more than 5800 kilometers and cross in the entire Atlantic Ocean. During their walks, the animals remain most of the time close to the surface, where the water temperature with 12 to 16 degrees is relatively warm.

Recovery is not in sight for the “management” of stocks of red tuna are responsible the International Commission for the Protection of the Atlantic tuna (ICCAT, International Commission for the conservation of Atlantic Tunas) and because of sharply declining stocks issued the EU who speak with a weighty Word has in the ICCAT and the 2007 even a regulation for the conservation of Atlantic Tunas. But to the urgently needed measures to rebuild of the stocks, a drastic reduction of fishing quotas for bluefin tuna, consistent monitoring, as well as a fishing stop during which were able to get for the preservation of the nature so important spawning so far neither EU nor ICCAT readjustments. Indeed, contrary to the recommendations of its own scientists, who warn against the collapse of stocks and had recommended an annual quota of 15,000 tons, the ICCAT for 2009 set a fishing quota for bluefin tuna of 22,000 tons, which will drop to only 19.950 tonnes in 2011. With a quota of 7,500 tons could give only the stocks a chance to regenerate. Critics call the ICCAT due to its blatant failure now as “international conspiracy to catch all tuna”. In setting annual fishing quotas – a prerequisite for effective fisheries management – device given the scale of illegal fishing more and more farce, as marine guards criticize. On the one hand it manages no longer to meet their quota of some fisheries.

In 2005, U.S. fishermen in the Western Atlantic could only 27% and in 2006 only 10 percent of them quota for bluefin tuna catch. On the other hand, the data situation is always unreliable for calculating quotas. ICCAT scientists for their calculations are based on the reported catches of the fishermen. And their honesty will be greatly reduced. So, far more bluefin tuna is imported into Japan than is actually possible on the basis of the permitted catches. Without a radical rethink in EU fisheries ministers and ICCAT, which so far is not in sight, it is foreseeable at the sushi or to the domestic fresh counter the Red soon no longer finding Thun will be.
