Nutritional role of natural productivity and formulated feed in semi‐intensive shrimp farming as indicated by natural stable isotopes by Gamboa Delgado, Julián

“…As in natural ecosystems, these dietary components exhibit differing isotopic signatures that vary with diet and trophic level. These isotopic differences can be used to infer the transfer of nutrients, as the isotopic values of prey items and consumers can be integrated in mass-balance mixing models, allowing the quantification of the relative contribution of multiple nutritional sources to the growth of a specific organism. …”

Recent Molecular Advances in Dietary Carbohydrate Utilization in Rainbow Trout by S. Powell, Madison

“…The goal of several current studies was to further refine our understanding of the metabolic use and adaptation to exogenous dietary carbohydrate in cultured rainbow trout.In one experiment, we assessed growth performance over a 10 week feeding trial along with post-prandial plasma glucose profiles, gene expression and enzyme activities to determine whether acclimation to a carbohydrate-rich diet is a consequence of size/age, or a result of transcriptional modulation or glucose sensing.…”
