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.
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.

In most decapod crustaceans the physiological processes of metamorphosis, molting and reproduction are inextricably linked and controlled by hormones.
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.
The use of refrigerated freshwater algal paste for production of rotifers results in live feed with adequate nutritional properties for marine larviculture.
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.
After numerous modifications during experiments with the freshwater prawn (Macrobrachium rosenbergii), a successful microbound diet has been developed.
Consideration of the effect of animal density usually does not include the critically important contribution of pathogen concentration to the dynamics of disease outbreaks.
Research with sockeye salmon fry in Washington state demonstrates that bioencapsulated artemia can deliver therapeutic erythromycin more efficiently than pelleted feeds.
In intensive fish hatcheries, successful larval rearing depends upon meeting larval metabolic demands with continuous feeding.
A study of hybrid tilapia breeding represents the minimum scale needed for achieving successful, in-house selective breeding.
Physical and chemical processes, along with the biological and economic components of shrimp production in zero-exchange culture, require models for analysis.
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 started in mid-2000, when traditional producers were at their lowest point due to the White Spot Syndrome Virus.
Consumer interest in water quality may prompt industry to further limit chemical use and improve biosecurity programs as an alternative to antibiotics.
Construction of an intensive aquaculture production facility without serious attention to biosecurity nearly guarantees outbreaks of infectious disease.
