Biofloc: novel sustainable ingredient for shrimp feed
Recent research is demonstrating that biofloc-based proteins are suitable replacements for fishmeal in aquaculture diets. Since bioflocs can be produced while treating aquaculture effluents, a waste product can be converted into a valuable resource.

Methionine-, sulfur-containing amino acids: Limiting nutrients in commercial formulations?
Trials indicated that in order to determine methionine and TSAA requirements for shrimp, methionine must be added to research feeds in either a chelated or covalently bound form.

Advances in triglyceride, fatty acid nutrition in penaeid shrimp
Dietary lipids are necessary for the growth, survival and metabolic functions. Triglycerides are the main form in which humans ingest and accumulate fat.

Study assesses fatty acid requirements, lipid levels of juvenile Pacific white shrimp
Study shows that increasing the dietary lipid level affected the lipid composition of shrimp by increasing lipid deposition in hepatopancreas and muscle tissue.
