Plant proteins effectively replace fishmeal in shrimp feed trial
A commercial-scale shrimp feed trial demonstrated that soybean meal and corn gluten meal are effective protein alternatives to fishmeal in shrimp feeds.

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.

Phytase supplementation in aquaculture diets improves fish, shrimp growth performance
Despite research challenges, ongoing work on phytase supplementation in shrimp is striving to enhance shrimp feed performance in similar ways.

Rethinking feeding for cultured shrimp
Underfeeding can slow growth rates and overfeeding adversely affects water quality so it is critical to adjust feeding rates to meet actual demands of shrimp.

Nutrient requirements of penaeid shrimp
Penaeid shrimp need the same nutrients required by all animals, including protein, lipids, energy sources, vitamins, minerals, oxygen and water.

Nutritional considerations for Pacific white shrimp reared in inland, low-salinity waters
Numerous environmental, social and economic advantages support the expansion of euryhaline shrimp and fish production away from coastal environments.
Health & Welfare
Stocking density, nursery duration influence shrimp growth, survival during grow-out
A nursery phase is a significant management strategy for many shrimp farmers in tropical regions and is becoming standard practice in subtropical regions.

Size-grading experiments yield strong advice for tilapia hatcheries
In an experiment in which tilapia were sorted by size and reared separately, large individuals maintained their size advantage after eight weeks of culture.

Live food enrichments enhance diets for larval yellowtail snappers
Yellowtail snappers produce small larvae that are a challenge to rear. Initial protocols have resulted in survival of only 3 percent from egg to juvenile.

Growth trials replace fishmeal in red drum diets
Given the finite supply of fishmeal and other marine protein sources, alternative ingredients are needed to replace fishmeal for production diets for marine fish.

Maximize feed efficiency through proper protein management
To control costs with feed efficiency, it is desirable to minimize the protein percentage, but reductions should not compromise shrimp performance.
