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.
Research in a culture system without water exchange indicated that biological performance of postlarvae was similar.
The effectiveness of carotenoid supplements will depend upon the severity of infection and other stress factors that affect the condition of the shrimp.
Only a few studies have been conducted with a few species. Shrimp vitamin requirements are simply trace amounts for maintenance metabolism and growth.
The static shrimp culture system did not negatively affect survival and had a positive effect on growth compared to the recirculating culture system.
