Evaluating soy lecithin supplementation in Nile tilapia raised in suboptimal temperatures
Soy lecithin phospholipids can be vital to improve the growth of Nile tilapia at suboptimal temperatures and offer an approach for new ingredients.
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.

The highly photosynthetic-efficient crop sorghum is a common grain and is also an aquafeed ingredient opportunity that can easily replace corn.
Health & Welfare
An assessment of seven insect meals demonstrates their high potential as protein sources to replace fishmeal in diets for L. vannamei.

A microbial-enhanced protein for juvenile Pacific white shrimp showed higher levels of hydrolysable protein and better digestibility than soybean meal.

Study examines impact of an increase in dietary NaCl on nutritional and other physiological processes, and effects on gut microbiome in Nile tilapia.
Aquafeeds
Facing shifting pricing and availability for traditional aquafeed ingredients, formulators are increasingly moving toward alternative starch and protein from plant sources like pea products.
Aquafeeds
Chlorella and other species have potential as protein sources in aquafeeds. In trials with tilapia fry raised in a recirculating system, the fish received a fishmeal-based control diet or feeds with portions of the fishmeal replaced by Chlorella.

A study of shrimp feeding demonstrated the digestibility of byproducts prepared from salmon livers, salmon milt, black cod viscera and arrowtooth heads and viscera from Alaskan fisheries processing plants.
Health & Welfare
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.
Health & Welfare
An eight-week growth trial evaluated the effects of potassium diformate on the growth performance and digestibility of Pacific white shrimp. Weight gain was not significantly affected by different levels of PDF in diets, and survival was high for all treatments.
Health & Welfare
In vitro pH-stat determination of digestibility is a promising technique for quick assessment of nutritional value and potential negative effects.
Health & Welfare
Determining the digestibility of protein and other nutrients in feed ingredients is an important step in the formulation of balanced feed.
