Glandless cottonseed meal replaces fishmeal in shrimp diet research
Cottonseed meal is high in protein and less expensive than fishmeal and soybean meal. Cotton plants can be engineered without gossypol in their seeds.

Twin screw technology for better extruded feeds
Extrusion processing can be a better alternative to produce high quality-low- polluting shrimp feeds. Extruded pellets with high water stability can be produced by controlling the Specific Mechanical Energy (SME) and without the inclusion of artificial binders. New extruders are equipped with state-of-the art SME controls that permit the adjustment of the SME to the desired range, to produce soft very hydrostable pellets.

Digestibility enhancer can offset cholesterol content in shrimp feed
Cholesterol is an essential nutrient for penaeid shrimp. Trials found that a digestibility enhancer based on natural emulsifiers was as effective as purified cholesterol in improving shrimp growth and feed conversion.

Biofloc: novel sustainable ingredient for shrimp feed
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.

Enteromorpha tested as shrimp feed ingredient
With vitamins, minerals, carotenoids and higher protein content than other species, Enteromorpha is a superior seaweed choice and a potential shrimp feed ingredient.

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.

SME controls help produce high-quality shrimp feed
Extruded pellets with high water stability can be produced without artificial binders by controlling the specific mechanical energy, or SME controls.

Physical qualities affect performance of shrimp feed
Formulated shrimp feed represents about 50 percent of production costs, but even more if the feed is wasted because of poor quality.

Trials test cottonseed meal as soybean replacement in shrimp feed
Cottonseed meal is a lower-cost protein alternative to soybean meal, but its use in commercial shrimp feeds may be limited because it contains gossypol.

Phospholipids in shrimp feeds
Phospholipids are compounds that combine a water-soluble phosphate group at one end with fat soluble fatty acids at the other.
