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

Abstract

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

The Use of Pine Apple Juice in the Elimination of Egg Stickiness in Catfish (Clarias gariepinus), Reared in a Hatchery, Sebeta, Ethiopia

“…Thus, at larvae and fry stages, low survival rates and poor growth performance are the major challenges in catfish production in Ethiopia. This is most probably related to egg stickiness, which needs to be reduced before eggs can be incubated successfully [3][4][5][6][7].…”
