Effective ingredient specifications yield quality feeds
Aquafeed manufacturers can ensure quality by looking beyond price and with written ingredient specifications adhering to nutritional formulations.
Enteromorpha tested as shrimp feed ingredient
With vitamins, minerals, carotenoids and higher protein content than other species, Enteromorpha is a superior seaweed choice and a potential shrimp feed ingredient.
Plant proteins effectively replace fishmeal in shrimp feed trial
A commercial-scale shrimp feed trial demonstrated that soybean meal and corn gluten meal are effective protein alternatives to fishmeal in shrimp feeds.
Vacuum process supports high oil content in feed coatings
Evolving vacuum coaters can apply coatings to feed with up to 40 percent oil levels. It may soon be used to reduce inclusion levels of fat- and water-soluble vitamins in feeds.
Hydrolyzed fish: Alternative ingredient for aquafeeds
Hydrolyzed fish byproducts can serve as highly digestible feed ingredients with significant amounts of amino acids and fatty acids.
Understanding oxidation: managing ingredient, food quality
Antioxidants can be effective at controlling lipid oxidation in animal feeds and ingredients and should be added early in processing to limit free radicals.
Microwave drying expanding to aquafeed production
Quick heating can reduce degradation of flavor and nutrient content in aquafeeds. Microwave dryers dry a range of products uniformly.
Palm distillate in catfish diets enhances growth, fillet quality
Palm distillate could be an effective substitute for fish oils in catfish diets. It is is a rich source of vitamin E and natural antioxidants.
Measuring shrimp feed water stability
Analytical procedures, like measuring water stability of shrimp feed, performed at labs provide more consistent and quantitative results.
Feed efficiency indicators for responsible aquaculture
While feed conversion ratios are often used as indexes of feed efficiency, they can be misleading as ecological indicators.
Suspended solids loads vary with feeding methods
In a feeding trial, organic suspended solids loads for tray-fed shrimp were much lower than those generated by mechanical dispersion.
Proper grinding of aquaculture feed ingredients
In grinding aquaculture feed to proper particle sizes, parameters of consideration include particle size distribution and pellet density.
Rethinking feeding for cultured shrimp
Underfeeding can slow growth rates and overfeeding adversely affects water quality so it is critical to adjust feeding rates to meet actual demands of shrimp.
Lipid nutrition of farmed tilapia
The optimum dietary lipid level for tilapia ranges from 10 to 15 percent. Various vegetable oil products show promise as replacements for fish oil in feeds.
Pilot-scale recirculating rotifer culture system uses condensed microalgae
Intensive rotifer culture systems can significantly reduce the space and labor requirements for the production of rotifers in marine finfish hatcheries.
SME-controlled extrusion process enhances water stability of shrimp
Shrimp feeds manufactured through the extrusion process can be produced with target quality attributes in a shorter time, thus improving feed production efficiencies.
