Aquafeeds
Consider feed quality, not just cost
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.
Responsibility
Certification programs for aquafeed manufacturing
Private aquafeed certification standards have been developed to bring trust and demonstrate responsible industry practices among aquafeed manufacturing stakeholders.
Aquafeeds
Single-cell proteins from food byproducts provide protein in aquafeed
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.
Responsibility
Oxygen demand of aquaculture feed
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.

U.S. agencies focus on fishmeal in feed
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.

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