Abstract

Tuna traps of the Sardinian and Mediterranean have provided from long- to short-term series of data and samples of bluefin tuna (BFT) populations inhabiting the Mediterranean. By analyzing genetic variation in bluefin tuna trap samples, we have shown that more than one bluefin tuna population has entered and spread in the Mediterranean over the last century and that over the short period, the interannual composition of the bluefin tuna trap catches are genetically constant
