Spatiotemporal genetic variation of atlantic bluefin tunas from sardinian and mediterranean tuna traps

摘要

Tuna traps of the Sardinian and Mediterranean have provided from long to short term series ofdata and samples of bluefin tuna (BFT) populations inhabiting the Mediterranean. Byanalyzing genetic variation in BFT trap samples, we have shown that more than one BFTpopulation have been entered and spread in the Mediterranean across the last century and thatover short period, the interannual composition of BFT trap catches are genetically constant.
