Fish and its resources has been an integral component of food security in many countries across the world, this is not limited to only coastal areas but also encompasses inland water bodies (Ahamed, Akter, Hasan, & Chakma, 2024). Human nutritional requirements depends also largely upon the resources obtained from fish such as lipids, high quality proteins (Nazeef, Ja’afaru, Ka, & Kabiru, 2021), and numerous minerals such as iodine and phosphorous (Ahamed et al., 2024).
The population dynamic parameters of Auchenoglanis occidentalis from Dadin-Kowa reservoir were studied. Population dynamic parameters such as growth, mortality and recruitment patterns were analyzed using length frequency data over 12-month period employing FiSAT II software. Findings revealed that LWR (b - constant) = 2.88, K = 0.72 -yr., L∞ = 40.91 cm and Tmax = 3.57 years and Ɵ’ = 3.14. Mortality indices revealed that natural mortality (M = 1.39), fishing mortality (F = 0.22) and exploitation ratio (E = 0.14), Lc/L∞ = 0.48, Emax = 0.64, while Lopt = 26.4 cm. Uni-modal recruitment peak observed with Lm = 27.3 cm. Restocking program is suitable to ensure its continuous existence as it seems to have low population.
