| The authors present the necessary to sort catfish and sea bream fries in order to limit cannibalism, to constitute homogeneous groups. In the same time they studied different sorters (bars sorter, grating sorter and the conception of an experimental sorter) and their effects on the juveniles (behaviour). Introduction: In hatchery, early sorting of Sea Bass or Sea Bream fry after weaning can become necessary for several reasons: a) To obtain homogeneous batches thus simplifying growing management by better controlling: - Specific water flow for precise ranges of size or weight, - Food distribution granularity, - Daily feeding rate. b) To limit cannibalism which can become high when population dispersion is spread out. This dispersion greatly increases... |
