Determinism and causative factors for morphological anomalies in reared European fishes

Publication . Boglione, C.; Fontagné, Stéphanie; Gavaia, Paulo J.; Gisbert, Enric; Kjorsvik, E.; Koumoundouros, Giorgos; Moren, M.; Moutou, K. A.; Witten, Paul

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

Dietary lipid quality regulates bone composition and metabolism in gilthead seabream (Sparus aurata) juveniles

Publication . Dias, J.; Rodrigues, V.; Colen, Rita; Rosa, Joana; Viegas, Michael; Cardeira Da Silva, João; Cancela, Leonor; Gavaia, Paulo J.; Laizé, Vincent

Replacement of significant amounts of marine fish oils by vegetable oils is a major trend in the aquaculture feed industry. However, knowledge on the mechanisms underlying the nutritional regulation of bone metabolism is extremely scarce in fish. We speculate that changes in the dietary ratio of fatty acids may modulate tissue eicosanoids production and affect bone formation in fastgrowing gilthead seabream, an important fish species for aquaculture in the Mediterranean region.
