GENETIC ANALYSES OF ATLANTIC NORTHERN BLUEFIN TUNA CAPTURED IN THE NORTHWEST ATLANTIC OCEAN AND THE MEDITERRANEAN SEA
tuna, Thunnus thynnus thynnus, reproduces as a panmictic unit. To address this question, we examined both mitochondrial DNA control region nucleotide sequences and nuclear gene ldhA allele frequencies in replicate samples of northern bluefin tuna from the Mediterranean Sea and the northwestern Atlan...
