Abstract

This study was aimed to observe the variation in size and growth change at maturity stage of both sexes for six Nemipterus species in the southern part of the Gulf of Thailand. Sample were collected using bottom trawl net was operated on board of “MV PRAMONG 9” research vessel during April -June, 2015. Male maturity stage-III of all fish species displayed largest average fork length 19.0±1.8, 11.1±2.6, 11.3±2.0, 19.3±4.4, 19.6±0.8 and 17.5±0.2, respectively. Similarly, female maturity stage-II was showed largest range of fork length 16.8±1.4, 9.8±0.3, 16.6±1.1, 16.3±1.3 and 16.5±0.9, respectively except N. mesoprion. Male fish was found larger in size than female for all species. Growth rate was higher at early stage of life for male fish and higher in adult for female fish. All species namely S. taeniopterus, N. mesoprion, N. furcosus, N. tambuloides and N. hexodon showed negative allometry according to growth value “b” observation except in N. nematophorus (positive allometry) in different maturity stages. Therefore, this study results can be used to help the fishery managers which can be used for maintain sustainable condition of Nemipteridae fish resources in the Gulf of Thailand and leading to a greater boost in the economy of Thailand.
