Two-dimensional proteomics as a tool to evaluate nutritional effects in farmed fish

Publication . Richard, Nadège; Gavaia, Paulo J.; De Vareilles, M.; Silva, Tomé S.; Cordeiro, O.; Rodrigues, Pedro; Conceição, L. E. C.

The use of proteomics in fish research is at a relatively early stage compared to terrestrial vertebrates. It has already been applied in the field of fish nutrition, enabling to point out metabolic changes occurring in response to dietary manipulations such as a variation in energy content, dietary nitrogen compostion, lipid composition or the incorporation of plant protein sources in aquafeeds.

Temperature affects skeletogenesis during Senegalese sole (Solea senegalensis, Kaup) larval development

Publication . Gavaia, Paulo J.; Dionísio, Gisela; Campos, C.; Carvalho, A. P.; Conceição, L. E. C.; Cancela, Leonor

The Senegalese sole (Solea senegalensis) is a highly valued species, with particular interest for the southern European aquaculture industry. For the last two decades this species has been transposed for industrial production, but it still presents some constraints as the high frequency of vertebral deformities observed under intensive rearing. The patterns of osteological deformities have previously been described and found to affect mostly the haemal and caudal vertebrae, but no studies have been conducted in order to identify causes for such deformities.

Effect of dietary vitamin K supplementation on skeletal development of Danio rerio

Publication . Dionísio, Gisela; Cancela, Leonor; Gavaia, Paulo J.

Nutritional imbalances affecting bone development have been implicated in the incidence of skeletal deformities, which are acknowledged to constitute one of the major constrains in the production of high quality fish. Several studies have focused on the identification of causes of deformities and associated them to factors such as rearing environment, nutrition and genetics. Among these, larval nutrition at first feeding is one of the key parameters affecting skeletogenesis during early development. Vitamin K (VK) is a liposoluble vitamin classically involved in blood coagulation, and until recently largely disregarded in aquaculture nutrition.

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.
