AFRICAN CATFISH In the African catfish hatching system, the fertilised eggs, obtained from the selected broodstock, will be placed and hatched. Each floating egg tray, one in each tank, should be stocked with 100 grams of fertilised eggs. This will result in a total stocking density of 400 eggs per cycle. The fertilised eggs are then evenly spread over the sieves of the floating egg trays and hatch in around 24 hours (when water temperature is around 29 degrees Celsius). The larvae will fall through the mesh of the egg trays while the non-hatched eggs will stay behind. Treating the eggs with...
