Aquaculture Nutrition and Growth

Aquaculture nutrition examines how farmed fish and shellfish convert dietary components—proteins, lipids, carbohydrates, and micronutrients—into tissue growth, guiding the formulation of feeds that keep production efficient and animals healthy. As wild-caught fish meal and fish oil become scarcer and more expensive, researchers are working to identify plant-based proteins, single-cell organisms, and insect-derived ingredients that can substitute without compromising growth rates or immune function. A central challenge is that fish vary widely in how they metabolize carbohydrates and fatty acids, so replacing conventional ingredients requires understanding species-specific biochemistry rather than applying a single formula. Active questions include how emerging feed technologies like biofloc systems alter nutrient availability, and how dietary composition interacts with gut microbiota to shape long-term fish health.
