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.
Proper grinding of aquaculture feed ingredients
In grinding aquaculture feed to proper particle sizes, parameters of consideration include particle size distribution and pellet density.
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.
Leaching impacts amino acid profiles of commercial shrimp feeds
The authors recently conducted a study to determine the amino acids content of commercial shrimp feeds the effects of leaching for six of them.
Artemia replacement diets for penaeid shrimp
At shrimp hatcheries, artemia replacement diets are used to replace live artemia, but complete replacement in commercial conditions remains a challenge.
SME controls help produce high-quality shrimp feed
Extruded pellets with high water stability can be produced without artificial binders by controlling the specific mechanical energy, or SME controls.
Vegetable-based trout feed boasts lower waste loads
New standards tighten the regulatory requirements for U.S. aquaculture producers regarding solid and dissolved pollutant loading in effluents.
Feeding strategies vary for shrimp producers
Shrimp are farmed globally in a wide range of production systems and fed under diverse feeding strategies throughout their life cycles.
Freshwater prawn feed management
Scale of operation and production rates dictate freshwater prawn feed management. Although labor-intensive, monitoring consumption with feed trays increases efficiency.
A closer look at preconditioning: Mixing, residence time
During the aquafeed manufacturing process, preconditioning increases the moisture content and temperature of feed meal particles.
CSIRO studies dry feeds for juvenile spiny lobsters
The Commonwealth Scientific and Industrial Research Organisation has researched pelleted dry feeds are palatable to juvenile tropical spiny lobsters.
Chemoattraction in aquatic feed management
The value of chemical stimulants to shrimp farming will come via reproducible methods to evaluate the efficacy of chemoattractants and feeding stimulants.
Antioxidants manage effects of oxidation on feeds, feed ingredients
Managing aquafeed quality from production of feed ingredients through manufacture, grow-out and processing is key in consistent, high-quality production.
Extrusion processing of aquatic feeds, Part 2
In the aquaculture industry, extruders have been used to produce a great variety of products, but today most of these feeds fall into the sinking or floating categories.
