Abstract:

AbstractCannibalism is an important characteristic of African catfish that significantly reduces the number of stocked fish at harvest. This study evaluates the effect of reciprocal hybridization of Clarias batrachus and Clarias gariepinus on cannibalism and growth performance of their progenies in an indoor rearing system. The result obtained reveals excellent performance of hybrids of C. gariepinus ♂ and C. batrachus ♀ over the purebreds in terms of growth. However, the reciprocal hybrids between C. gariepinus ♀ and C. batrachus ♂ all died few hours after hatching. Cannibalism was significan

Abstract:

Growth of African catfish (Clarias garipinus) is characterized by large size heterogeneity resulting in poor growth performance and cannibalism. Strategies that limit size heterogeneity in C. gariepinus culture are therefore advocated. This study determined the effects of grading frequency on the growth performance and cannibalism of C. gariepinus in tank culture system. Three treatments designated as G0 (no grading), G2 (grading every 2 weeks) and G4 (grading every four weeks) in a Completely Randomized Design (CRD) was applied in triplicate. The tanks were stocked with 200 fingerlings each.

African catfish (Clarias gariepinus) is one type of freshwater fish that has high economic value. African catfish with intensive cultivation are hampered by the high cost of feed that is not in accordance with the selling price of African catfish. An alternative effort that can be done is the addition of probiotics to feed which is expected to reduce feed costs. Probiotics are living microorganisms in fish culture that can prevent disease, thereby increasing production and can reduce economic losses.
