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.
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.
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.
Viral testing spurs proactive measures for Fiji’s black tiger shrimp
As Fiji considers a change in culture species from blue to black tiger shrimp, a study evaluated viruses in the country’s wild P. monodon stocks.
Loose shell syndrome causes low-level mortality in India’s black tiger shrimp
Loose Shell Syndrome is a slow killer of black tiger shrimp in India. Affected shrimp exhibit mortality and reduced survival rates and production.
Tilapia vaccines: important disease prevention, biosecurity tools
Tilapia vaccines can protect the fish against infectious diseases by providing pathogen-specific acquired immunity that prevents recurring infections.
Nucleotide supplementation may offer health benefits in cultured fish
Dietary nucleotide supplementation represents a potential means to enhance aquaculture efficiency and profitability, but gaps in current knowledge exist.
Freshwater fish culture in China
About 60 percent of China’s aquaculture production is freshwater fish. Carps top the list, although many other native and non-native species are also raised.
