Aquaculture Feeds and Nutrition

Fish, both farmed and wild, require a balanced mix of essential nutrients, amino acids, fatty acids and energy. Traditionally, fish feeds have contained a high percentage of fishmeal and fish oil because the balance of nutrients most closely resemble the requirements of fish. However, partial or total replacement of fishmeal and fish oil in feeds is becoming the norm. Feeds eliminating these ingredients have been used experimentally to feed farmed Atlantic Salmon, Rainbow Trout, Red Sea Bream, Grouper, White Sea Bass, and Cobia. Fish in these studies show similar growth and survival to those fed on feeds containing fish meal and fish oil.
