Onset of sexual maturation results in energy allocation towards gonad maturation rather than body growth and also in deterioration of flesh quality. Accidental farmed escapees result in unwanted ecological and genetic interactions between wild and cultured fish. The production of sterile (triploid) fish has been considered an option for reproductive control and genetic containment in Atlantic salmon and other species meeting both industrial and environmental criteria. The performance triploid salmon is currently under large-scale commercial evaluation in Norway and the product will be available on the market soon.
As in the case of other artificially produced sterile fish, little is known about the nutritional requirement of triploid salmon. Identifying the optimal conditions for production of triploids is important, as is the characterization of the functional consequences (physiological and morphological) of the procedure. Recent studies carried out in our consortium have revealed significant differences in gut morphology between diploid and triploid fish raised on the same diets and under similar conditions. Detailed information on the ontogeny of the digestive system in triploids and its characterization in terms of morphology, key enzymes’ activity and gene expression is still lacking for salmon and other important cultured species. In this project, we wilI assess the functional ontogeny and physiology of triploid salmon digestive system using a specialized diet that could be in synergy with the gut morphology of the triploid salmon.
