Sexual growth dimorphism in penaeid shrimp
Sexual growth dimorphism occurs in cultured aquatic species like tilapia, catfish and salmon, and has also been reported for cultured crustaceans.
Lipid profiles in farmed fish
Studies comparing the differences between farmed and wild fish lipid profiles have been conducted, but there is no standard format for reporting.
Amino acid balance affects protein levels in catfish feeds
Catfish feeds used in trials at LSU were formulated to possess an amino acid balance similar to that of the channel catfish body.
Phosphates and shrimp
Commercial experience and research have demonstrated that phosphates can enhance sensory quality and increase consumer appeal for shrimp. Through over 10 years of research with shrimp from around the world, the Aquatic Food Products Lab at the University of Florida in Gainesville, Florida, USA has shown that consumers prefer shrimp properly treated with phosphates. However, processors must have a clear understanding that misuse of these ingredients can result in poor appearance, poor texture, and consumer rejection.
Harvesting head-on shrimp
EU markets have special requirements for head-on shrimp. Organoleptic criteria are evaluated, including firmness of shell and head, malformations and color.
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.
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.
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.
