| Abstract | Stock assessment of spotted golden goatfish, Parupeneus heptacanthusalong the Andaman Sea coast of Thailand by collecting data from trawlers, which landed at fishing ports in Ranong, Phuket, Trang and Satun Province during January to December 2013. The fishing ground areas wereThai-Myanmar boundary, Payam Island, Surin Island, Similan Island, YaoyaiIsland, Phiphi Island, Rok Island, TabaiIsland, BuloanIsland, Adang Island, Tarutao Island and Thai-Malaysian boundary. Average catch per unit effort of this species caught by otter board trawler size less than 14 m, otter board trawler sizemore than14 m and paired trawler were 0.07, 0.36, and 1.11kg/hr, respectively. Sizedistribution of total in numberof fish wasintherangeof 5.0-31.0 cm. Growth parametersincluded; the asymptoticlength (L∞) was 35.00 cm, curvatureparameter(K) was 1.10 per year and can be formedthe von Bertalanffy growth equation was Lt = 35.00 (1-e-1.10(t-0.00)).For mortality coefficient included, Total mortality (Z), natural mortality (M) and fishing mortality (F) were 4.26, 1.86, and 2.40per year, respectively. The first group of recruitment inthefishingground was 5.0-6.0 cm with 33.77millionfish. In 2013, the estimated catch of this species was 919.66 tons while the maximum sustainable yield (MSY) was 921.87tons at the F-factor 0.90 and the maximum economic yield (MEY) was 53.39million baht at the F-factor 0.70. The results showed thatthe catch of this fish in 2013 was over MSY.For the effective management of this resources trawlers fishing effort about 10 percentshould be reduced. Moreover,increasing the cod endmesh size as optional measure from 2.5 cmto 5.0 cm can be resultedin a yield increase of943.28 tons. |
