Australian test studies potential of probiotics in oyster hatcheries
At oyster hatcheries around the world, prevention and control of infectious bacterial diseases has involved the use antibiotics and disinfectants.
High-pressure processing offers varied applications
High-pressure processing can destroy or inactivate microbial cells in seafood to improve shelf life, quality and food safety.
Temperature, salinity affect egg survival, hatching rate in bullseye puffers
In Mexico, there is interest in the culture of various finfish species, including bullseye puffers, a commercially important fish with aquaculture potential.
Yucca extract reduces ammonia concentrations in Mexico shrimp trial
The authors evaluated the effects of a yucca extract on water quality and the production parameters of Pacific white shrimp.
Diet size affects shrimp feeding behavior, growth performance
To understand shrimp feeding behavior, the Oceanic Institute investigated feed delivery systems and responses to experimental diets.
Microsatellites: Applications in aquaculture
Microsatellites are useful for molecular tagging of individuals and molecular dissection of complex traits such as growth, temperature tolerance and disease resistance.
SPF fleshy prawns show potential for genetic improvement
In a recent effort to produce specific pathogen-free (SPF) stocks of the fleshy prawn, researchers from two U.S. institutions collaborated.
Functional genomics studies explore shrimp responses to viral pathogens
The aim of functional genomics on innate antiviral immunity in marine shrimp is to characterize the genes involved in the response to WSSV and other viruses.
Selective breeding raises WSSV resistance in fleshy prawns
With the fleshy prawn (Fenneropenaeus chinensis), family selection appears to be a promising prospect that could enhance WSSV resistance.
Improved salmonid quality through selective breeding
Salmonid farming efficiency and profitability can be increased by improving the ability of fish to incorporate carotenoids from feed into their flesh.
Iodinated feed reduces stress in steelhead trout
A study at Purdue hypothesized that when provided with iodine, the thyroid would increase the production of thyroid hormones in steelhead trout.
High-pressure processing variably affects similar microorganisms
High hydrostatic pressure processing can improve shelf life, quality and safety of seafood products, but microorganisms’ responses vary significantly.
Inland prawn farming trial in Australia
The development of inland prawn farming using low-salinity groundwater may allow Australia’s prawn farmers to expand beyond the coastal fringe.
Brown muscle syndrome in shrimp
Idiopathic muscle necrosis or IMN causes “brown muscle syndrome” in black tiger prawns in Thailand, as well as other penaeid shrimp.
Influencing sex ratios in Nile tilapia
Environmental factors can influence the sex ratios of fishes, and this knowledge could be useful to develop all-male Nile tilapia stocks without hormones.
Cooperative efforts drive marine finfish aquaculture development in Asia-Pacific
A regional workshop in Malaysia was the starting point for an initiative to promote cooperation in marine fish aquaculture in the Asia-Pacific region.
