Nutrition and Fish farming

Knowledge of the nutritional requirements of farmed fish is currently less advanced than what is known for land animals, e.g. poultry, pigs, ruminants. Several factors may explain this difference: the recent domestication of most species of aquaculture interest, the diversity of fish species reared worldwide, and the difficulty to conduct experiments within an aquatic environment.
However, recent scientific efforts undertaken by both research organizations and aquaculture industries have allowed for the collection of a significant amount of data on fish nutrition. The findings have been applied by feed manufacturers and fish farmers in their attempts to change their feed’s composition without compromising livestock performance.

This section addresses issues that relate to the nutrition and feeding of different species of farmed fish. Key-definitions, tools, methods and concrete cases are meant to illustrate the bases of fish nutrition and its recent developments.
