| Sumario: | Due to their nutritional properties, several species of macroalgae have been used as dietary supplements for shrimps and other marine species. Since macroalgae represent a natural source of nutrients in the shrimp’s natural environment, attempts have been done to co-culture macroalgae and shrimps. The nutritional performance and digestibility of macroalgae-derived meals have been tested in formulated diets for shrimp. One of the aspects requiring further research is represented by the loss of nutritional properties occurring when the macroalgal biomass is dried out as compared when the algal biomass is ingested as live biomass. Several nutritional methodologies have been used to evaluate the performance of different ingredients used or proposed for aquaculture feeds. The use of stable isotopes as tools to assess nutritional contributions of specific ingredients to growth is one of many emerging nutritional techniques applied in aquaculture. |
