Seasonal migration, site fidelity, and population structure of European seabass ( Dicentrarchus labrax )
Abstract Large-scale electronic tagging is a very powerful tool to study how fish movements and migrations shape the internal dynamics of populations. This knowledge, crucial for improving fishery management, was still limited for the European seabass, whose stocks in the Northeast Atlantic have dec...
