Dr. Addison Lee Lawrence, a well-known shrimp aquaculture researcher who authored or co-authored many Advocate articles, passed away in October at the age of 86.
Health & Welfare
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.
Innovation & Investment
Optical scanning and associated imaging software reduces stress and increases accuracy as compared to traditional techniques for shrimp measurements.
Health & Welfare
The authors designed changes for single- and twin-screw extruders that streamlined the extrusion process to achieve higher output rates for small-diameter aquafeeds.
Health & Welfare
Single-celled proteins in bioflocs can provide protein and other nutrients in shrimp feed, but what makes them enhance growth performance in shrimp?
Aquafeeds
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.
Responsibility
In pilot-scale research, researchers found that both sequencing and membrane batch reactors removed ammonia, nitrite and suspended solids with great efficacy.
Health & Welfare
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.
Health & Welfare
Despite research challenges, ongoing work on phytase supplementation in shrimp is striving to enhance shrimp feed performance in similar ways.
Health & Welfare
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.
Aquafeeds
The value of chemical stimulants to shrimp farming will come via reproducible methods to evaluate the efficacy of chemoattractants and feeding stimulants.
Health & Welfare
Dietary lipids are necessary for the growth, survival and metabolic functions. Triglycerides are the main form in which humans ingest and accumulate fat.
Health & Welfare
Study shows that increasing the dietary lipid level affected the lipid composition of shrimp by increasing lipid deposition in hepatopancreas and muscle tissue.
Health & Welfare
Of all the issues important to shrimp nutrition, the reduction of feed cost with concomitant increased feed performance are most desirable.
Health & Welfare
Phospholipids play important roles in maintaining normal cell structure and functions and are sources of second messengers in cell signaling.
Health & Welfare
A Texas A&M study showed that temperature affects sperm quality of Pacific white shrimp, the top commercial shrimp species in the Americas.
