Dietary effects of fish oil, soy lecithin on shrimp in clear and greenwater systems
A 56-day trial conducted in greenhouse-enclosed clearwater and greenwater systems compared tissue variations among shrimp fed varied dietary levels of fish oil and soy lecithin.

Spotted sea trout studies identify nutrition requirements, benefit of exercise
The authors performed nutrition studies to determine a maximized efficiency of yield in spotted sea trout. Fry were “forced” to swim against a steady current to gauge the effectiveness of increased exercise.

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.

Chemoattraction of low-molecular-weight compounds in shrimp feeds
The methodology used in a Texas Agricultural Experiment Station study provided a useful tool for evaluating the attractiveness of individual ingredients in prepared shrimp feeds.

Chemoattraction in aquatic feed management
The value of chemical stimulants to shrimp farming will come via reproducible methods to evaluate the efficacy of chemoattractants and feeding stimulants.

Protein-energy ratio research in penaeid shrimp
Of all the issues important to shrimp nutrition, the reduction of feed cost with concomitant increased feed performance are most desirable.
