As part of the development of rearing procedures at the first commercial marine fish hatchery in Venezuela, a study induced spawning of lane snappers and evaluated the survival of larvae fed rotifers, two microalgae species and enriched artemia.
A whole genome sequence allows the identification of candidate genes responsible for production and performance traits for a given species. Ongoing genome projects include programs for Atlantic salmon, Atlantic cod, Pacific oysters, tilapia, catfish and shrimp.
The amount of fishmeal and fish oil used in aquaculture has remained static, while output from aquaculture has increased.
Microbial surveys of hatchery operations at Oceanic Institute found a strong correlation between hatchery success and cultivable bacteria levels in the water supplied to the larval-rearing systems.
Coloration in crustaceans is affected by a combination of factors: diet, environment and genetics. The genes required for coloration are not present in any other animal, but crustaceans use them to create a variety of colors and shell patterns.
Spiny lobsters have a long, complex life cycle. Growing them through larval stages is a particular challenge. Spiny lobster culture is currently centered in Vietnam, where the industry depends on wild-caught animals for stocking and trash fish for feeding.
Due to the inherent complexities of field testing, definitive laboratory-based test methods can better quantify probiotic benefits.
The transfer of resistance from an aquaculture pathogen into a human enteric bacterium has been demonstrated in research and may be happening in the real-world environment.
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.
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.
Improving the methodology of antimicrobial resistance testing and related controls, and the implementation of laboratory ring tests could lead to more reliable information.
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.
The levels of harmful Vibrio bacteria – a pathogen that multiplies at higher temperatures – in raw oysters depend largely on post-harvest handling.
The authors induced out-of-season spawning in pike perch reared under natural and artificial temperature and illumination regimes.
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.
The authors conducted a study to investigate the prevalence of IHHNV in P. vannamei within the context of a family-based genetic selection program.
