Biofloc technology offers advantages for the sustainable culture of shrimp and some species of fish.
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.
A study compared the effects of two forms of methionine supplemented at different levels in feeds for Pacific white shrimp. Test diets containing methionine bound in soy protein had less leaching of methionine than the diets containing crystalline methionine.
A study found the quality and levels of sterol supplements in experimental feeds affected the growth performance of Pacific white shrimp.
Research in culture systems without water exchange indicates that dietary protein levels have great impact on dissolved inorganic nitrogen loading.
