A recent study in Brazil tested the efficacy of nine commercial feed attractants for Litopenaeus vannamei. Condensed fish-soluble protein, an amino acid complex with digested bivalve mollusk, and whole squid protein hydrolysate stimulated the highest feeding responses.

The authors conducted a study to determine how reducing the protein content of a diet would affect the growth performance of L. vannamei reared in an experimental microbial floc culture system.
A study in Brazil indicated that mutton snappers, a high-value species that readily accepts artificial food, can grow well on diets containing high-quality plant proteins such as soy protein concentrate.
A study showed that lipid source and DHA and EPA levels in feeds can influence the growth performance and tail fatty acid profiles of L. vannamei farmed under hypersaline conditions.
A feed enrichment study showed that dietary lipid source and content of EPA and DHA in the diets of shrimp influenced the fatty acid profiles of their tails.
In a study, krill meal incorporated into shrimp diets replaced fishmeal and soy lecithin with no significant effect on shrimp performance.
Shrimp diets need amino acid composition, balance and availability. Protein digestive capacity appears related to both nutrient availability and composition in feed.
