Identification and characterisation of microsatellite markers in narrow barred Spanish mackerel Scomberomorous commerson (Lacepede, 1800)

Abstract

Narrow barred Spanish mackerel, Scomberomorus commerson (Lacepede 1800) is one of the commercially important fish in Indian waters. For sustainable management of the species, it is necessary to understand the genetic stock structure of the species. Accurate delineation of genetic stock structure can be achieved using nuclear microsatellite markers. A study was carried out to identify and validate polymorphic microsatellite markers in S. commerson using information available from closely related fish species. The study could identify 10 polymorphic microsatellite loci which can be effectively utilised for identifying genetic stock structure of the species. Validation of the identified loci was also done by testing the loci in natural populations of the species. The findings of the present study will be useful in devising stock-specific management measures for conservation and sustainable utilisation of this commercially important fish species in Indian waters.

Research Article Isolation and characterization of polymorphic microsatellite markers for the chub mackerel (Scomber japonicus) and cross-species amplification in the blue mackerel (S. australasicus).

“…Moreover, they have been widely developed and used in the study of population genetics of many species (Guo et al, 2016;Mohanty et al, 2016;Tan et al, 2016). Furthermore, some of these microsatellite markers developed for Scomber species have been successfully used for amplification in other related species (Tang et al, 2009;Divya et al, 2016). However, it is not very sufficient, and some locus-by-population tests exhibited significant departure from Hardy-Weinberg equilibrium (HWE) (Cheng et al, 2015).…”
