Characterization of 15 polymorphic microsatellite loci in the temperate reef fish Lepadogaster lepadogaster, developed using 454-sequencing

Abstract

Abstract The clingfish, Lepadogaster lepadogaster is a reef fish species, abundant in temperate nearshore rocky reefs of the Eastern Atlantic and central and Eastern Mediterranean. To study genetic variability and population connectivity of this species, we developed fifteen polymorphic microsatellite markers. These were tested in one population and all but one, showed no departure from Hardy–Weinberg equilibrium. Average overall observed heterozygosity was 0.66 and allelic richness was 8.9. Two primer pairs revealed possible linkage disequilibrium. These markers open perspectives for population genetic studies of this species to unravel connectivity and population biology, vital information for future conservation studies.
