Managing pre-harvest off-flavors in pond-raised catfish
Although causes of pre-harvest off-flavors in catfish differ due to climate, water quality and pond hydrology, blue-green algae is a common culprit.
Gene-based markers could aid selective breeding
Stress hormone axes could be used as markers for selective breeding. Researchers see a negative correlation between weight gain and cortisol response to acute stress.
Blue shrimp quarantined in New Caledonia genetic variability program
To improve the sustainability of their breeding programs, shrimp producers in New Caledonia established a program with certified SPF blue shrimp.
UNC-Wilmington conducts research on black sea bass
Studies at UNC-Wilmington found that growth and survival of black sea bass larvae were improved through supplementation of DHA and ARA in live feed.
Quality parameters in farmed Atlantic salmon
Studies have identified changes in the quality parameters of farmed Atlantic salmon and wild salmon that reflect changes in the animals’ life cycles, diets and environments.
Seafood allergies: Control, prevention key to workplace management
Occupational seafood allergies can manifest as asthma, rhinitis, conjunctivitis, urticaria, and dermatitis. Anaphylactic reactions have also been reported.
Fishmeal replacements: Rendered protein meals effective
Research indicates that rendered protein meals could replace significant amounts of fishmeal in diets for shrimp and several cultured fish species without reducing weight gain.
Clay particles an alternative water treatment in marine fish larvae tanks
Clay particles present an alternative to water treatments with microalgae or algae paste in the culture water of marine fish larvae.
Low-salinity fish production technology can cut costs, aid biosecurity
Virginia Tech Aquaculture Research Group collaborated with MariCal to examine commercial feasibility of raising cobia in RAS under low-salinity conditions.
Feed preparation for white sea bass, totoaba broodstock
Hubbs-SeaWorld Research Institute and Universidad Autónoma de Baja California are working to produce improved broodstock diets for white sea bass and totoaba.
Marine fish stocking studies demonstrate species adaptability, environmental quality
Stocking marine fish in coastal impoundments in Florida, USA, has demonstrated improved habitat quality and given hatchery fish a transition to open water.
Domestication of Pacific white shrimp revolutionizes aquaculture
The development of specific pathogen-free Pacific white shrimp and breeding led to rapid adoption of the domesticated shrimp throughout the Western Hemisphere and Asia.
Genetic improvement in Brazil
Breeding efforts at Aquatec Genearch Aquacultura in Brazil have centered on specific pathogen-free white shrimp lines imported from the United States.
Atlantic cod genomics and broodstock development project
The Atlantic Cod Genomics and Broodstock Development Project has expanded the gene-related resources for the species in Canada.
Shrimp breeding in Australia
Experiences with newly domesticated shrimp species in Australia underscore the importance of understanding the species' biological requirements.
Persistent biofilms problematic in aquaculture, food processing
Resistant to antibacterial agents and heat, biofilms are difficult to remove from food-processing surfaces and may result in persistent pathogen populations.
