Poor-quality ingredients can’t become good-quality ingredients. Quality protein is essential for the healthy growth of any omnivorous or carnivorous aquaculture species. Insect meals seem to fill this need, and their mass-scale production appears to be sustainable. 

In life cycle analysis of aquaculture, there is a danger of the entire array of embodied resources and impacts being assigned to the production facility. Producers have no control over the inefficiencies or impacts associated with feed production, but can help lessen resource use through good management practices. 

A growth trial in Canada evaluated the use of algae biomass to increase the concentration of long-chain polyunsaturated fatty acids in the tissues of rainbow trout. 

Private aquafeed certification standards have been developed to bring trust and demonstrate responsible industry practices among aquafeed manufacturing stakeholders. 

Since feed costs can contribute up to 60 percent of the expenses for an aquaculture business, it is common for farms to purchase lower-cost feeds. 

Wastes produced during food processing can be treated to generate a valuable single-cell protein ingredient for aquafeed with protein and amino acid content similar to fishmeal. 

The oxygen demand of feed represents the dissolved oxygen removed by the respiration of culture animals, microbial decomposition of uneaten feed and feces, and oxidation of ammonia nitrogen by nitrifying bacteria. 

The National Oceanic and Atmo­spheric Administration and U.S. Department of Agriculture joined forces through the NOAA-USDA Alternative Feeds Initiative to identify feed ingredients that will reduce the amount of fishmeal and fish oil in aquaculture feeds while maintaining the human health benefits of seafood. Through research on a variety of sources, promising alternatives are beginning to emerge. 

Quick heating can reduce degradation of flavor and nutrient content in aquafeeds. Microwave dryers dry a range of products uniformly.
