Spawning, length-growth, mortality and exploitation rate of galeoides decadactylus exploited from the artisanal fisheries of Sierra Leone

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 macroscopically assessed total length-frequencies from growth models FiSAT II software. Gonadosomatic Index the stock peaked October alongside Hepatosomatic Index, attained first sexual maturity at lengths 19.8 cm (female) 25.7 (male,). Infinity length (L∞) was 43.3 cm, rate (K), 0.34 yr-1), theoretical age (t0), -0.7 years, lifespan (tmax), 8.1 years exponent (b), 2.78. Total (Z), natural (M) fishing (F) gave 1.58 year-1, 0.77 year-1 0.81 respectively, whereas current (Ecurrent) 0.51 year-1. The optimum effort (Fopt) limit (Flimit) 0.31 respectively. Results implied occurrence major spawning October, negative allometric growth, short high pressure on stock. Recalibration measures is advised.
