Embryos of perch are harvested from ponds and incubated in laboratory. Larvae are fed successfully with artemia nauplii. About two days after hatching, the gas bladder is filled with atmospheric air. Larval development study shows that larvae are not fully developped at hatching. Yolk sac entire resorption is completed at two weeks old. A week later, there are significant changes : twin cones appear in the retina which was pure cone at hatching; numerous gill lamellae are present ; the pronephros is replaced by a mesonephros with an adult kidney structure. The digestive tract simple and rectilinear at hatching, is curly and more developped with the presence of three pyloric coeca. Larval rearing tests demonstrate the necessity of a recircul...
