O.I. study confirms fishmeal quality in feed effects growth performance
The quality of fishmeal used as a dietary ingredient can influence the feed utilization and growth of the aquaculture species.
New ingredients for shrimp feeds, Part 1
New ingredients and processes are figuring prominently in the production of more-nutritious and better-balanced “specialty" shrimp feeds.
Are on-site feed mills right for shrimp farmers? Part 2
Ingredients are the major cost in the operation of a feed mill, so feasibility analyses should include real ingredient costs as well as manufacturing costs.
Report reviews feed practices in shrimp aquaculture
New feed practices can reduce environmental impacts of shrimp farming, including the replacement of fishmeal and fish oil with sustainable lipid sources.
Rendered meals workable feed ingredients for Pacific white shrimp
Rendered meals, or feeds with ingredients made from animal byproducts, meet many important criteria and have excellent prospects for aquaculture feeds.
Blue mussel extracts stimulate flounder feeding
A water-soluble fraction of blue mussels improved the growth of juvenile Japanese flounders by increasing feeding.
Live food enrichments enhance diets for larval yellowtail snappers
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.
Dietary lysine in plant protein diets improves rainbow trout performance, water quality
Evaluating trout performance fed diets with supplemental lysine in plant protein meal, and total ammonia nitrogen and soluble phosphorus excretion.
Incorporation of local soybean meal in diets for black tiger postlarvae
Soybean meal is increasingly being used in aquaculture feeds due to its nutritional quality and lower cost than animal protein sources.
Tests study fresh marine ingredients in shrimp larval diets
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.
Are on-site feed mills right for shrimp farmers? Part 1
Before shrimp farmers consider an on-site feed mill for aquafeed production, they should ask themselves tough questions and ponder all the risks.
CLA-enriched diets improve health benefits of catfish fillets
CLA-enriched diets (with conjugated linoleic acid) have become a recent focus of fatty acid research because of their health benefits to humans.
Attractants: The basics
Attractants are used in the aquafeed industry, where rapid identification and consumption of feed is very important in the aquatic environment.
Fishmeal, fish oil replacements in sea bream, sea bass diets need nutritional compensation
Fishmeal and fish oil replacements present a challenge for the aquafeed industry. The range of alternative protein and fat sources is limited, given multiple considerations.
Trial finds extruded feeds superior to steamed pellets
A feeding trial in Hawaii tested the nutritive value of extruded feeds in comparison pelleted feeds for Pacific white shrimp.
Microencapsulated, composite-wall diets compare well to commercial feeds for shrimp larvae
Diet microencapsulation using a biopolymer composite wall is a novel way to protect diet ingredients against deteriorative mechanisms such as oxidation and leaching.
