Poster: Genetic Population Structure of Some Small Pelagic Fishes in the Sulu-Sulawesi Marine Ecoregion (SSME)
Pedrosa-Gerasmio Ivane UNDP-GEF Sulu Celebes Sea Sustainable Fisheries Management Project (SCS SFM): Stock Identification Study/ National Fisheries Research and Development Institute Altair Agmata and Mudjekeewis D. Santos SSME, small pelagics, stock structure, mitochondrial DNA Pelagic fish dominate the world's fisheries, constituting one of the few major food sources harvested from wild populations. They likewise are the major food source in the Sulu-Sulawesi Marine Ecoregion (SSME) bordered by Indonesia, Malaysia and Philippines. The management of this resource is thus of prime importance, though basic biological information, especially relating to population structure, is often lacking. In this study, the genetic population structure of some commercially important small pelagic fishes sampled from SSME countries using a total of 309, 305, 326, and 364 base pairs (bp) of the mitochondrial DNA region was investigated for frigate tuna (Auxis thazard), Bali sardine (Sardinella lemuru), Indian mackerel (Rastrelliger kanagurta) and Big-eyed scad (Selar crumenophthalmus), respectively. High percentage of variation, low overall FST value, high haplotype diversity shown in a scattered Median-Joining haplotype network are indicative of panmixia in the Sulu-Celebes Seas. Therefore, any management practice to be implemented in the area should consider that the three countries (Indonesia, Malaysia and Philippines) are sharing the said stocks. Indeed, mtDNA data indicate that management plans for these pelagic fishes require SSME-wide cooperation and governance.
