Quantitative, molecular genetic selection for shrimp disease resistance
The aquaculture industry has developed management strategies to strengthen shrimp disease resistance, like diagnostic systems and biosecurity.
Norwegian researchers develop sea lice tracking model
An operational salmon lice model calculates sea lice infestation pressure all along the Norwegian coast in near real-time, based on a hydrodynamical ocean model and a salmon lice particle tracking model.
Moon phases influence snook spawning, egg quality
Snook are indigenous to coastal waters from Florida, USA, to Brazil. Mote Marine Laboratory has spawned snook for stock enhancement research.
AquaMaof cultivating a ‘new generation’ of fish farmers
Israel-based AquaMaof has seen its RAS technology rolled out to 10 facilities around the world, with more still in the pipeline.
Hydrogen peroxide treatments improve catfish embryo survival
Without hydrogen peroxide treatments, pathogens like fungi and bacteria can overtake the egg mass and significantly reduce channel catfish embryo survival.
Robotic vehicle applications in aquaculture
Small autonomous vehicles provide an environmentally friendly approach to labor-intensive methods used to maintain production and water quality.
In-pond raceway systems introduced in Pakistan
In-pond raceway systems have potential to improve farmed fish production in Pakistan. Production of grass carps, rohu carps and tilapia is being tested.
SPF-defined pathogen-free status of shrimp limited
Specific pathogen-free status depends on the presence or absence of specific pathogens. This status depends on the level of biosecurity for the shrimp.
Pink shrimp hatchery production in Florida
The authors developed hatchery techniques for producing Florida’s native pink shrimp for the Crystal River Mariculture Center.
Genetically male vs. mixed-sex Nile tilapia performance compared in RAS
A promising strain of Nile tilapia is the genetically male tilapia that results from the mating of sex-reversed female fingerlings with normal females.
Bioencapsulated artemia show promise for therapeutant delivery to young fish
Research with sockeye salmon fry in Washington state demonstrates that bioencapsulated artemia can deliver therapeutic erythromycin more efficiently than pelleted feeds.
Cholesterol: Indispensable but not irreplaceable in shrimp feeds
Penaeid shrimp are unable to bio-synthesize cholesterol, which is widely accepted as an essential nutrient for these crustaceans.
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.
L. vannamei trials in Indonesia improve productivity
In L. vannamei trials in Indonesia, results confirmed that somewhat lower protein levels in feed had no effect on production performance.
Sustainable and profitable shrimp farming in Saudi Arabia
A team of engineers and specialists has built an intensive shrimp farm in Saudi Arabia, proving sustainability doesn’t have to adversely affect profitability.
WSSV scare in Australia
Australia’s prawn industry has encountered its first scare over white spot syndrome virus (WSSV) following positive test results in the northern territories.
Advantages of aerated microbial reuse systems with balanced C:N, part 1
An alternative waste treatment is intense microbial processing of wastes to facilitate high yields with little or no water exchange.
Reducing nitrogen waste: An integrated approach
In shrimp farming it is critical to ensure that residual nitrogen waste is minimized or eliminated prior to discharge into receiving waters.
