摘      要：This study describes for the first time the reproductive biology of the coastal trevally(Carangoides coeruleopinnatus)(Ruppel,1830)caught from Terengganu waters,*** sample collection from April 2019 to March 2020 was done at Pulau Kambing fish landing port in Terengganu,Malaysia.A total of 687 individuals comprise of 362 males(52.69%)ranged from 6.3 cm to 26.6 cm(mean±SD:13.2±3.84 cm)and 325 females(47.31%)ranged from 9.0 cm to 26.4 cm(mean±SD:13.9±3.34 cm)were *** sex ratio significantly deviated in favor of males(1:0.90)(χ^(2)=1.99).However,there are significant differences between sexes over months in June(χ^(2)=10.89),July(χ^(2)=11.91),August(χ^(2)=6.10)and September(χ^(2)=4.41).The monthly variation of the gonadosomatic index(IG)peaked between February and April for males and females,indicating its spawning *** interpretation between condition factor(K)and hepatosomatic index(IH)showed that the energy mobilization from the body assists the gonad *** batch fecundity of 42 mature females ranged from 15.7 cm to 21.4 cm,and mass was 142.6 g-333.0 g giving 20,438 to 121,829 *** length at first maturity of males and females were 12.45 cm and 15.78 cm,*** male reached earlier maturity than the *** study increases the understanding of reproductive aspects of *** for future formulation of rules and regulations for suitable fishery management in Terengganu waters.
