Determinism and causative factors for morphological anomalies in reared European fishes

摘要

The presence of sublethal morphological deformities represents one of the main bottleneck of the industrial finfish hatcheryproduction, resulting in major economic loss due to reduced growth and marketing ability of the final product, that has to betransformed (filets) or sold for fish flour. Furthermore, the elimination of deformed fishes from the productive cycle needsfor periodic selections at present carried out by manual sorting. This represents an additional economic cost, and a stressfor fishes.
