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.
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.
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.
First commercial lobster culture module established in Norway
A new scalable modular concept for lobster culture developed in Norway relies on automation to perform most production procedures.
Reengineering Dipasena
A revitalization of the huge integrated Dipasena Citra Darmaja farm complex is directing individual farmers to raise white shrimp using biosecure protocols in a modular culture approach.
Self-recruiting species diversify polyculture systems
Even in commercial systems, management of self-recruiting species within diverse polycultures can reduce risk and produce valuable byproducts.
Semen cryopreservation research seeks higher fertility rates in rainbow trout
A USDA/ARS program is studying semen cryopreservation with rainbow trout to insure that genetic diversity from multiple populations and the genetic legacy of selectively bred populations are protected.
Shrimp behavior may affect culture performance at super-intensive stocking densities
Results from two studies at Oceanic Institute indicated that shrimp behavior may compromise growth at super-intensive stocking densities.
Russian study examines behavior of red king crab postlarvae
The release of cultured red king crab juveniles into the ocean presents a possible way to enhance stocks. Research in Russia found that early crab postlarvae did not feed, but swim actively.
