Abstract

Effects of Different Physiological Saline Concentrations on the Reproductive Performance of Clarias gariepinus (Burchell, 1822)

This study aimed to investigate the effect of different concentrations of physiological saline (0, 3, 6 and 9 g/l as control) on the reproductive performance of Clarias gariepinus within 7 days of induced breeding. At the end of the experiment, there were significant increases (ANOVA, p>0.05) in fertilization, hatching and survival rate with an increase in physiological saline concentration up to 6 g/l. Values were (mean ± standard deviation, SD, %) 94.3 ± 1.1, 88.8 ± 3.0 and 78.7 ± 2.3 for fertilization, hatching and survival rate respectively. The physico-chemical parameters were measured and values were within the ideal range for C. gariepinus production. Overall, the results indicated that milt prepared in 6 g/l physiological saline concentration is the most ideal for fertilization, hatching and survival of C. gariepinus larvae
