Abstract

Epinephelus fuscoguttatus belongs to one of the largest serranidae fish family. Genetic information regarding existing fish populations in the wild is crucial for the conservation, particularly since the species is listed under the IUCD Red List due to intense fishing. Microsatellites of E. fuscoguttatus were isolated using streptavidin-biotin enrichment method. In total, 378 microsatellites were identified and characterized. Of these 378 total microsatellites, 46 (12.2%) were mononucleotides, 175 (46.3%) were dinucleotides, 109 (28.8%) were trinucleotides, 36 (9.5%) were tetranucloetides, 7 (1.9%) were pentanucleotides, 4 (1.1%) were hexanucleotides and 1 (0.3%) was a heptanucleotide. The most abundant microsatellite present in E. fuscoguttatus was the dinucleotide motif, (AC)n.

Key words: Enrichment, Epinephelus fuscoguttatus, microsatellite, diversity.
