Biofloc technology options for aquaculture
Biofloc technology offers advantages for the sustainable culture of shrimp and some species of fish.
Intelligence
Addison Lawrence, dedicated shrimp aquaculture researcher, remembered
Dr. Addison Lee Lawrence, a well-known shrimp aquaculture researcher who authored or co-authored many Advocate articles, passed away in October at the age of 86.
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.

Methionine supplement form affects feed leaching, but not shrimp growth
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.
Health & Welfare
Effects of sterol supplements on shrimp growth, survival
A study found the quality and levels of sterol supplements in experimental feeds affected the growth performance of Pacific white shrimp.

Nitrogen management for shrimp nutrition in low water-exchange production systems
Research in culture systems without water exchange indicates that dietary protein levels have great impact on dissolved inorganic nitrogen loading.
Responsibility
Shrimp production systems with low/no water exchange
Research in a culture system without water exchange indicated that biological performance of postlarvae was similar.
Health & Welfare
Carotenoid supplements and WSSV
The effectiveness of carotenoid supplements will depend upon the severity of infection and other stress factors that affect the condition of the shrimp.
Health & Welfare
Initial evaluation of shrimp vitamin requirements in laboratory tanks without water exchange
Only a few studies have been conducted with a few species. Shrimp vitamin requirements are simply trace amounts for maintenance metabolism and growth.
Health & Welfare
Recirculating and static shrimp culture systems
The static shrimp culture system did not negatively affect survival and had a positive effect on growth compared to the recirculating culture system.
