Challenges associated with carrying out a meta-analysis of essential amine acid requirements fish

摘要

High cost of fishmeal, the volatility in the price of agricultural commodities and the stagnant price of aquaculture products are constraining aquafeed manufacturers to pay very close attention to the cost-effectiveness of their feeds. Nutritionists are required to formulate to lower or narrower essential nutrient specifications in order to minimise feed cost. At the same time, these feeds must sustain high growth, feed efficiency, health and product quality of the animals at the farm. Nutritionistsalso are relying on an increasingly diverse portfolio of 'economical' protein sources, with different amino acid profiles. Thus, formulating cost-effective aqua-feeds requires increasingly precise information on essential amino acid (EAA) requirements ofaquaculture species.
