Aquafeeds

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. 

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 (with conjugated linoleic acid) have become a recent focus of fatty acid research because of their health benefits to humans. 

Attractants are used in the aquafeed industry, where rapid identification and consumption of feed is very important in the aquatic environment. 

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. 

A feeding trial in Hawaii tested the nutritive value of extruded feeds in comparison pelleted feeds for Pacific white shrimp. 

Diet microencapsulation using a biopolymer composite wall is a novel way to protect diet ingredients against deteriorative mechanisms such as oxidation and leaching. 

There is limited information on the quality characteristics and performance of shrimp grow-out diets manufactured in the United States. 

Antinutritional factors within plant feedstuffs is a major factor that limits plant use at high dietary inclusion levels in aquafeeds. 

In the crumbling process of pelleting, whole pellets are crushed to produce starter diets used to feed different stages of shrimp in their early development. 

Shrimp postlarvae diets can be fed entirely artificial, but the best growth rates are obtained when feeds include artemia or enriched artemia. 

Synthetic and natural binders that provide increased water stability are often used without consideration of the final dry or wet pellet texture of the shrimp feed.
