Electron beam treatment can inactivate pathogens in foods. E-beams could be applied to fish as a pasteurization/sterilization step without changing product temperature.
In a challenge study of catfish families identified as resistant or susceptible to enteric septicemia (ESC), immune response was activated 24 hours earlier in resistant families and bacterial levels were suppressed.
Juvenile SPF Kona-line shrimp were injected with V. penaeicida, causing significant disease, but certain bacterial concentrations allow survival long enough for additional testing.
Technical literature varies in reporting the ability of vitamins to improve fish survival and resistance to disease following infection with pathogens.
RAS technology can be applied to shrimp culture. The author developed a small-scale prototype RAS for shrimp larval culture that successfully reared monodon nauplii to PL15.
U.S. trials indicated wild-caught pampano could be feed trained and spawned in captivity via hormonal induction. Observations of fecundity, egg fertilization rates, and spawning frequency suggested that quantities of pompano seedstock could be produced over time. Although survival during test larviculture was low, the trials showed pompano larvae can be reared following standard commercial practices.
Although hepatitis E is infrequent in developed nations, additional cases may occur due to global travel patterns and importation of seafood.
Studies show that peracetic acid can reduce microorganisms on food products and effectively act against pathogenic and spoilage organisms.
The nodaviruses that can infect the nervous systems of Atlantic cod threaten further expansion of the burgeoning cod-farming industry.
Although aquaculture offers potential for the production of California halibut, several aspects of production have yet to be optimized.
A finely tuned fishing diet can improve growth and feed utilization of sea bream grown previously on diets with low levels of fishmeal and fish oil.
Hepatitis A virus (HAV) is a widespread and serious foodborne pathogen commonly associated with shellfish-vectored outbreaks.
Research at the Achotines Laboratory in Panama has been inconclusive involving probiotic treatments of first-feeding larval tuna and the rotifers they eat.
A study in Ecuador found that pellet stability and the overall physical properties of feed pellets greatly influences the consumption of shrimp feeds with varied types and proportions of binder agents.
A study found the quality and levels of sterol supplements in experimental feeds affected the growth performance of Pacific white shrimp.
The growing Pacific oyster culture industry in Australia is supported by cooperative research on genetic improvement and broodstock distribution.
