Pollack (Pollachius pollachius): Acquisition of biologic data in a breeding purpose

The fishing of pollack which concerns essentially, France, United Kingdom and Norway, and at a lower level Ireland and Denmark, is situated between 10 and 15000 tons a year. In 1996, France was the first producer of Pollack. Since 1980, a decrease of production is observed in Europe. In France, landing reached 3000t. in 1998 (Suquet, 2001). However, the demand remaining strong, aquaculture could be a solution to satisfy the deficit between the French production and the domestic demand.
