Spatial and temporal population genetic analysis of Semaprochilodus insignis (Prochilodontidae), an overexploited fish from the Amazon basin.

ABSTRACT:

Background

Semaprochilodus insignis is a migratory fish of commercial and subsistence importance to communities in the Amazon. Despite the high intensity of exploitation, recent studies have not been carried out to assess the genetic status of its stocks.

Methods

This study is the first to estimate genetic diversity and to test the existence of spatial and temporal structuring of S. insignis through sequencing of the mtDNA control region (n = 241) and eight microsatellite loci (n = 180) of individuals sampled at 11 sites distributed in the Brazilian Amazon basin.

Results

Results for both markers were congruent, revealing a homogeneous genetic diversity in all the sampled locations, in addition to the absence of spatial and temporal genetic
