Régime alimentaire et pourcentage de survie chez la larve de sole (solea solea l.)

The first metamorphoses during rearing of flounder larvae were obtained at the beginning of the century, in France, by Fabre-Domergue and Bietrix (1905). Sixty years later, their experiments were taken over by Fluchter (1965-1972) in Germany, and Shelbourne (1968) in Great-Britain. The first one focused on the laboratory study of the impact of the water quality on the rearing success, and the latter, on the development of industrial hatcheries. Both obtained metamorphosis with survival rates varying from one egg laying to the other and reaching 80 % in the best batches. They explain these variations through genetic differences or pathological phenomena.
