摘要

In most major aquafeed-based intensive aquaculture production systems there is a high reliance on nutritionally balanced complete aquafeeds. In situations where on-farm feeds are made, farmers attempt to produce a balanced feed using vitamin and mineral ers are increasingly looking for alternative sources of feeds such as trash fish, animal by-products and grain by-products, or are reverting to the use of single ingredient supplementary feeding regimes, reduced feeding frequency and ration. These types of interventions to mitigate against rising feed costs will compromise fish growth, health and welfare and could reduce fish productivity and production.
