Chemoreception in the aquatic environment: A primer
As marine-ingredient replacement with plant proteins continues, it's important to supplement diets with attractants to stimulate feeding behavior.
Maximize feed efficiency through proper protein management
To control costs with feed efficiency, it is desirable to minimize the protein percentage, but reductions should not compromise shrimp performance.
Advantages of aerated microbial reuse systems with balanced C:N, part 1
An alternative waste treatment is intense microbial processing of wastes to facilitate high yields with little or no water exchange.
Control of dietary phosphorus in flounder culture
A feeding trial evaluated five dietary protein sources on growth performance and phosphorus-retention efficiency in olive flounders.
Determining physical stability of shrimp feeds
Maintaining the stability of shrimp feeds until consumption is a challenge as pellets lose dry matter due to leaching of soluble compounds.
Feed management for RAS, part 1
RAS inputs and outputs are easily quantified, but even an efficient system will appear to have higher operating costs than a traditional pond.
Feeding tray technique improves shrimp feed management in Brazil
It is common practice to broadcast feed throughout a shrimp pond with a few feeding trays to help monitor consumption and adjust ration size.
Determining optimal dietary protein level for Litopenaeus vannamei postlarvae
A report on the results of a study to determine the optimal dietary protein level for postlarvae Pacific white shrimp in a recirculating culture system.
Nutritional disorders and aquatic animal health
Dietary nutritional disorders in farmed aquatic animals can be broadly defined as diet-related imbalances due to “under-” or “over-” nutrition.
Trials show promise for spray-dried plasma protein in shrimp feeds
Spray-dried plasma protein is a high-protein feed ingredient that can lower occurrence of enteric disease when used in feed or water.
Advances in shrimp postlarval nutrition
A variety of factors – postlarval nutrition, disease treatment and control of microflora – contribute to optimal hatchery operations.
Broodstock nutrition: Effects of nutrient levels
There is limited information available concerning the optimal requirements for broodstock nutrition for most of global aquaculture production.
Phospholipids in shrimp feeds
Phospholipids are compounds that combine a water-soluble phosphate group at one end with fat soluble fatty acids at the other.
Shrimp feed management in Australia
A shrimp feed management survey indicated that Australian farmers placed a high importance on better estimations of feed demand in improving FCR.
Rendered animal byproducts: A necessity in aquafeeds for the new millennium
Of all the sources of animal protein and energy available for aquafeeds, the largest is rendered animal byproducts.
Worms: A potential feed source for cultured aquatic animals
The use of worms – insect larvae, terrestrial earthworms and aquatic oligochaetes – in fish and shrimp culture is generating interest.
