Nutrient and light availability control food webs and fish larvae in the Peruvian upwelling system
Abstract Upwelling ecosystems sustain some of the world's most productive fisheries by supplying deep‐water nutrients to the sunlit ocean surface. Yet, how spatiotemporal variability in nutrient‐upwelling and light availability regulates trophic transfer to fish remains poorly understood. We investigated these dynamics in a 36‐d mesocosm experiment off

This study aimed to evaluate the effects of replacing fish meal with poultry viscera meal (PVM) in diets for juvenile Arapaima gigas, assessing growth performance, hematological parameters, fillet composition, and gut and liver histology. Five isonitrogenous (450.20 g kg−1 crude protein [PRO]) and isocaloric (20.02 MJ kg−1 gross energy) diets were ...
