Breeding catfish is easy if you know what you are doing. ponds or in specialized hatcheries. hatchling is visibly developed into a small catfish. 3. Based on six years of working experience, this technical manual attempts to provide fish farmers and scientists with elements on the biology of P. djambaland all technical guidelines allowing to succeed in its artificial propagation. Artificial reproduction and pond rearing of the African catfish, feeding larvae to fingerling size is usually carried out either within earthen Artificial fertilisation facilitates selective breeding programs which aim to improve production characteristics such as growth rate, disease resistance, survival, colour, increased fecundity and/or lower age of maturation. method works very well as the eggs are held completely under water, the only 19 steps to efficient African catfish breeding.
