Feeding strategy supports freshwater prawns without fishmeal, fish oil
Low-input culture practices for freshwater prawns can manage their growth and biological characteristics so they can be fed no fishmeal or fish oil.
Herbivorous or omnivorous fish like tilapia can be fed lower-energy and lower-protein diets because they consume higher amounts of feed than carnivores.

Live diets for reared marine larvae must be cost-effective and versatile while providing good nutrition and being easily captured and digested. Copepods offer superior nutritional value, but their rearing requires space and is laborious.
Microminerals participate in a variety of biochemical processes and must be supplied in prepared diets to support optimal growth and production efficiency.
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.
The authors conducted a study to determine how replacement of salmon meal with various animal protein meals in feed affected the growth performance of white shrimp.
Cottonseed meal is high in protein and less expensive than fishmeal and soybean meal. Cotton plants can be engineered without gossypol in their seeds.
About 30 percent of global microalgae production goes to animal feeds, with large applications in aquaculture, particularly for larval stages.
In its efforts to advance sustainable aquaculture practices and the use of soy-based feeds in Southeast Asia, the American Soybean Association International Marketing Program (USAIM) has identified several challenges.
Simple economic modeling can show that by considering aquaculture production inputs as investments rather than costs, opportunities for increased profits can be quickly identified.
Solid-state microbial fermentation for upgrading nutritional characteristics of raw plant materials is a potential pretreatment for animal feeds.
India's fish-farming industry makes limited use of modern feeds, providing potential for the feed sector to grow. Commercial feeds are predominantly used for pangasius farming, followed by a rising popularity in carp culture.
In a trial, lipid oxidation and metmyoglobin formation in the dark meat of yellowtail during chilled storage were significantly controlled by feeding mushroom extract to the fish as a supplement.
Alternative lipids have achieved varied success in ensuring adequate growth and fatty acid composition in fillets. The authors evaluated rainbow trout raised on diets containing fish oil or a blend of fish and standard or modified lipids varying in fatty acid composition.
The simplest tool for assessing phytoplankton abundance in aquaculture ponds is the Secchi disk. An electronic turbidimeter can be used to measure the amount of light scattered by a water sample.
EWOS and Canadian researchers have developed a model to measure the ecological footprints of aquafeeds using ISO-compliant lifecycle analysis methodologies.
