Science for glass eel fisheries management: How to define TAC in France?
To tackle the low level of European eel stock, the European Union Council has adopted in 2007 a regulation for establishing measures for the recovery of the stock of European eel. In application of this regulation France established an eel management plan that includes, among others, measures to dec...
