Genetic diversity, variation, and structure of two populations of bigfin reef squid (Sepioteuthis lessoniana d'Orbigny) in Con Dao and Phu Quoc islands, Vietnam.

ABSTRACT:

Background

Bigfin squid is one of the economically important seafood resources in Vietnam's fisheries and the waters around Con Dao and Phu Quoc islands are two major fishing grounds where this species has been actively exploited. The start codon targeted polymorphism (SCoT) and CAAT box-derived polymorphism (CBDP) techniques were used to generate DNA fingerprinting data to analyze the genetic diversity, variation, and structure of the two populations in the waters surrounding Phu Quoc and Con Dao islands together with mitochondrial cytochrome C oxidase subunit I (COI) gene sequence data.

Results

Con Dao population possessed a higher diversity [expected heterozygosity (H_e) = 0.2254, Shannon index (I) = 0.3459, percentage of polymorphic bands (PPB) = 80.14%, nucleo
