• Coastal trevally, Turrum coeruleopinnatum is one of the commercially important species caught from Terengganu waters, Malaysia. Lack of biological information available for this species inspire this study. The population parameters such as length-frequency distribution, length-weight relationships, and growth parameters of T. coeruleopinnatum were studied where fish sample were collected from the trawlers that landed at fishing port in Pulau Kambing, Terengganu from April 2019 to March 2020. Of 687 individuals examined, 362 were males (52.69%) and 325 were females (57.31%). The size of samples ranged from 6.3 to 26.6 cm LS (mean ± SD: 13.2 ± 3.84 cm) and body mass between 11.5 and 635.8 g (109.9 ± 93.5 g). This study found that T. coeruleopinnatum has negative allometric growth pattern with the growth coefficient (b) values were 2.7984, 2.7814, and 2.7937 for males, females, and pooled sexes respectively. The ages of fish was determined by counting the number of opaque rings in sectioned otolith where seven age groups were identified. Von Bertalanffy growth parameters of the males, females and pooled sexes were as followed: SLT =190.48 [1 – exp {-0.40(t-0.27)}], SLT = 57.91 [1 – exp {-0.71 (t – 0.21)}] and SLT = 153.55 [1 – exp {0.37 (t – 0.08)}] respectively, where SLT if standard length (cm) at age t. This study provides new references of T. coeruleopinnatum in Terengganu waters, South China Sea, Malaysia for the enrichment of fisheries database and relevant fishery management in the region.
