Aquaculture Nutrition and Growth

Aquaculture nutrition examines how farmed fish and shellfish convert dietary components — proteins, fatty acids, and carbohydrates — into growth, and what formulations best support health across different species and life stages. As global fish meal and fish oil supplies remain constrained, researchers are working to identify plant-based proteins, microbial biomass, and alternative lipid sources that can substitute for wild-caught ingredients without compromising feed efficiency or the nutritional quality of the harvested animal. A central open question is how different species tolerate and metabolize carbohydrates, since most farmed fish have limited capacity to use them as an energy source compared to terrestrial livestock. Emerging approaches like biofloc technology, which cultivates microbial communities directly in culture water as a supplemental feed source, are also being evaluated for their potential to close nutrient loops and reduce the environmental footprint of intensive aquaculture systems.
