HACCP risk management tool controls viral pathogens at shrimp facilities
An approach like HACCP, which integrates risk assessment, management and communication is necessary to minimize unintended consequences.
Development, implementation of shrimp health programs require integrated effort
Shrimp health management focuses on disease prevention through good nutrition, sound pond management, and stress reduction rather than disease treatment.
Objective quality assurance
Since microbiological analyses do not provide a desired degree of reliability, chemical tests have been proposed for farmed fish quality assurance.
Chloramphenicol in shrimp: Europe as food safety utopia
The detection of the antibiotic chloramphenicol in shrimp exported to Europe from Asian countries brought about a flood of reactions.
Ecuador study shows wild postlarvae use down
During the 1970s and 1980s, Ecuador's shrimp industry relied almost entirely on wild postlarvae but has since developed large hatcheries.
Zero-exchange demonstration posts good results in Nicaragua
The Nicaragua Small Shrimp Producer Assistance Program built a closed, zero water-exchange shrimp production system to demonstrate the concepts and practices.
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.
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.
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.
