865 specimens of Galeoides decadactylus were analysed for spawning, length-growth, mortality and exploitation rates in May-October 2020, to support with management information. Gonads were macroscopically assessed and total length-frequencies analysed from growth models in FiSAT II software. Gonadosomatic Index of the assessed stock peaked in October alongside Hepatosomatic Index, and attained first sexual maturity at lengths 19.8 cm (female) and 25.7 cm (male,). Infinity length (L∞) was 43.3 cm, growth rate (K), 0.34 yr -1 ), theoretical age (t0), -0.7 years, lifespan (tmax), 8.1 years and growth exponent (b), 2.78. Total (Z), natural (M) and fishing mortality (F) rates gave 1.58 year -1 , 0.77 year -1 and 0.81 year -1 respectively, whereas the current exploitation rate (Ecurrent) was 0.51 year -1 . The optimum fishing effort (Fopt) and fishing limit (Flimit) were 0.31 year -1 and 0.51 year -1 respectively. Results implied occurrence of major spawning in October, negative allometric growth, short lifespan and high fishing pressure on the stock. Recalibration of management measures is advised.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
