Study identifies white spot variants in Sinaloa, Mexico
Mexico's government, shrimp industry and academic community are working to develop strategies to attenuate the effects of white spot virus in Sinaloa. They confirmed eight genotypes.
Fatty acids in feeds improve growth, lipid profiles of white shrimp farmed at high salinity
A study showed that lipid source and DHA and EPA levels in feeds can influence the growth performance and tail fatty acid profiles of L. vannamei farmed under hypersaline conditions.
Flaws in reporting antimicrobial resistance
Improving the methodology of antimicrobial resistance testing and related controls, and the implementation of laboratory ring tests could lead to more reliable information.
Proactive disease management counters ISA, IMN
Although many companies avoid the costs associated with setting up proactive disease management infrastructure, failure to do so can result in losses that far outweigh the costs.
Vibrio contamination in raw oysters controlled by post-harvest treatments
The levels of harmful Vibrio bacteria – a pathogen that multiplies at higher temperatures – in raw oysters depend largely on post-harvest handling.
Out-of-season spawning for pike perch
The authors induced out-of-season spawning in pike perch reared under natural and artificial temperature and illumination regimes.
Aquaculture in Armenia
Fish farms in Armenia have developed a diversified product base that includes value-added, ready-to-eat foods for export, as well as live and processed fish for domestic markets.
Testing may help increase IHHNV tolerance in Pacific white shrimp
The authors conducted a study to investigate the prevalence of IHHNV in P. vannamei within the context of a family-based genetic selection program.
Delousing salmon in large net pens
In research for Norway’s salmon farmers, the authors documented effective bath treatments against sea lice infestations in large net pens using skirts or tarpaulins to define the treatment area.
Trout farming in South Africa
Trout farming is a well-established industry that assists in providing services and technology to developing aquaculture sectors in South Africa.
New Norwegian RAS farm produces salmon smolts
The Fjordsmolt RAS farm applies a relatively simple, low-cost design to produce millions of salmon smolts per year in fiberglass tanks.
Evolutionary history of Taura Syndrome Virus
Based on a phylogenetic analysis with the BEAST program, the authors determined the evolutionary relationships among 83 Taura syndrome virus isolates.
Probiotics and disease control in aquaculture
The use of probiotics in aquaculture is steadily gaining momentum, supplementing or replacing the use of antimicrobial compounds in disease control.
Artificial incubation, hormonal sex reversal promoted tilapia boom
The tilapia production boom results from technology that combines artificial egg incubation and monosex fry production using hormonal sex reversal.
X-ray irradiation: Technology improves safety of live oysters
Various techniques have been proposed to reduce Vibrio bacteria in live and processed oysters. In studies, X-ray treatments successfully reduced Vibrio populations.
Tilapia fingerlings from varied systems deliver similar grow-out performance
Results of a 120-day study showed that Nile tilapia fingerlings produced in incubation units, hapas or ponds exhibited similar grow-out performance.
