Genetic population structure of red snapper ( Lutjanus malabaricus) and orange‐spotted grouper ( Epinephelus coiodes) in Brunei and Sabah

Abstract The genetic population structure of red snapper Lutjanus malabaricus and orange‐spotted grouper Epinephelus coiodes in Brunei and Sabah was investigated using allozyme electrophoresis. Samples were collected from three sites in Brunei for E. coiodes and from three sites in Brunei and Sabah for L. malabaricus . A total of 22 loci and 16 loci were scored, respectively. The index of fixation ( F ST ) for the E. coiodes population was 0.176 but, in general, it lacked within‐population structuring. The F ST was particularly high between Brunei Bay/Jerudong and Brunei Bay/ Kuala Belait, sug... Mehr ...
