A study at Purdue hypothesized that when provided with iodine, the thyroid would increase the production of thyroid hormones in steelhead trout.
New feed practices can reduce environmental impacts of shrimp farming, including the replacement of fishmeal and fish oil with sustainable lipid sources.
Rendered meals, or feeds with ingredients made from animal byproducts, meet many important criteria and have excellent prospects for aquaculture feeds.
A water-soluble fraction of blue mussels improved the growth of juvenile Japanese flounders by increasing feeding.
Yellowtail snappers produce small larvae that are a challenge to rear. Initial protocols have resulted in survival of only 3 percent from egg to juvenile.
Evaluating trout performance fed diets with supplemental lysine in plant protein meal, and total ammonia nitrogen and soluble phosphorus excretion.
Soybean meal is increasingly being used in aquaculture feeds due to its nutritional quality and lower cost than animal protein sources.
In a study at the University of Wales in the United Kingdom, a larval shrimp diet that included fresh marine ingredients was compared with a control diet.
High hydrostatic pressure processing can improve shelf life, quality and safety of seafood products, but microorganisms’ responses vary significantly.
Before shrimp farmers consider an on-site feed mill for aquafeed production, they should ask themselves tough questions and ponder all the risks.
