Study is a model for investigations to identify critical genes for EHP survival and spread as targets for preventive and therapeutic management.
Aquafeeds
Protein hydrolysates can be used as partial substitutes for fishmeal in P. vannamei nursery diets to maintain digestive enzyme activities.
Health & Welfare
Responses to enhance cold tolerance included regulating changes in genes, metabolites and amino acid and lipid metabolism to increase energy supply.

An estimation model identifies genetic variances across mating combinations for stress resistance traits and families with heightened stress tolerance.
Aquafeeds
Black soldier fly larvae meal can effectively replace fishmeal in shrimp diets if nutrient balance and price sensitivity are properly considered.
Innovation & Investment
A genome assembly of L. vannamei provides valuable resources for future genetic research, breeding and improvement of traits for aquaculture.

Chinese ginseng can improve the immune responses of shrimp by increasing the hemocyte count and regulating intestinal digestive enzymes.
Health & Welfare
Two dietary single-cell protein sources promoted growth, immunity and digestion and improved intestinal microbiota stability in L. vannamei shrimp.
Health & Welfare
Piperine at doses of 0.1–0.4 percent can be a valuable feed additive to improve the growth, feed utilization, immunity, digestibility and disease resistance of L. vannamei.

For the best growth and highest level of in vivo antioxidant activity, the optimal level of the grape extract Nor-grape 80 is 250–500 ppm.
Aquafeeds
Brown mussel meal at inclusion levels of 1.73–2 percent is a potential additive in L. vannamei shrimp diets to promote growth and reduce FCR.
