Trial finds microalgal paste suitable for rotifer nutrition
Rotifers are a dominant zooplankton that are a preferred prey for larval fish and one of the live feeds most often used by fish culturists.
Role of hormones in shrimp growth, reproduction
In most decapod crustaceans the physiological processes of metamorphosis, molting and reproduction are inextricably linked and controlled by hormones.
Refrigeration affects fatty acid profile of microalgae
The use of refrigerated freshwater algal paste for production of rotifers results in live feed with adequate nutritional properties for marine larviculture.
Sodium bisulfite treatments improve shrimp appearance but require proper disposal
Dip shrimp in a 5 percent sodium bisulfite solution for 2 to 5 minutes to produce a bisulfite concentration of 30 to 50 ppm sulfur dioxide equivalent in the shrimp.
Microbound diet proves successful as replacement for artemia nauplii
After numerous modifications during experiments with the freshwater prawn (Macrobrachium rosenbergii), a successful microbound diet has been developed.
Animal density, pathogen load related factors in disease outbreaks
Consideration of the effect of animal density usually does not include the critically important contribution of pathogen concentration to the dynamics of disease outbreaks.
Bioencapsulated artemia show promise for therapeutant delivery to young fish
Research with sockeye salmon fry in Washington state demonstrates that bioencapsulated artemia can deliver therapeutic erythromycin more efficiently than pelleted feeds.
Automation for intensive fish hatcheries
In intensive fish hatcheries, successful larval rearing depends upon meeting larval metabolic demands with continuous feeding.
Genetic improvement of tilapia at commercial RAS
A study of hybrid tilapia breeding represents the minimum scale needed for achieving successful, in-house selective breeding.
Zero-exchange shrimp production: Design and modeling
Physical and chemical processes, along with the biological and economic components of shrimp production in zero-exchange culture, require models for analysis.
OceanBoy Farms: Challenges of inland, freshwater production of shrimp in Florida
OceanBoy Farms in Southern Central Florida has been a leader in establishing commercial protocols for inland, low-salinity shrimp farms.
Inland shrimp farming in Ecuador
Inland shrimp farming in Ecuador started in mid-2000, when traditional producers were at their lowest point due to the White Spot Syndrome Virus.
Water quality concerns may move up food chain
Consumer interest in water quality may prompt industry to further limit chemical use and improve biosecurity programs as an alternative to antibiotics.
Biosecurity in intensive aquaculture: Don’t build without it
Construction of an intensive aquaculture production facility without serious attention to biosecurity nearly guarantees outbreaks of infectious disease.
Freshwater trial with Litopenaeus vannamei leads to further stocking in Panama
Panama shrimp farmers looking to boost production in the presence of White Spot Syndrome Virus have tried various strategies, including freshwater systems.
Determining ion concentrations for Litopenaeus vannamei culture in freshwater
Future increases in U.S. shrimp farming are likely to be inland, which entails the use of ground waters with an ion concentration vastly different from seawater.
