    Better Defining Nutritional Requirements of Fish and the Nutritive Value of Feed Ingredients: Lessons from Integration of Experimental Data from a Wide Variety of Sources por P. Bureau, Dominique

    Publicado 2011
    “…Small but meaningful improvements in the objectives, scope, and experimental design of research trials, as well as, in the quality and completeness of information reported in scientific papers could greatly improve the quality and relevance of research efforts in aquaculture nutrition.Research trials should be designed with the perspective of potential end users (e.g. feed manufacturers) in mind. Nutrient requirements trials should not ideally have fewer than six (6) graded levels of the nutrient studied and report sufficient information on the composition and digestibility of the experimental diets, and growth performance and body composition of the experimental animals. …”

    Application of Stable Isotopes in Aquaculture Nutrition Research por Focken, Ulfert

    Publicado 2008
    “…The ratio of the stable isotopes(13C/12C, 15N/14N) of the diet is transferred (with a small, but important modification) to the tissue of the fish.Therefore, the analysis of stable isotopes in fish tissues provides information on the isotopic composition of thefish’s diet. This analysis is of special interest in semi-intensive aquaculture systems, in which the growth depends onnatural food as well as on compound feed, and in which alternative methods for the study of diet composition aredifficult to apply. …”
