Scombrotoxins, part 1
Without proper control of seafood handling and processing, high amino acid content and bacterial activity can rapidly elevate concentrations of biogenic amines like scombrotoxins.
Scombrotoxins, part 2
Since biogenic amines are a health issue in seafood, harvesters and processors should understand what conditions encourage their formation, where they form in fish, and how they are affected by bacterial flora.
E-beam treatments could improve seafood safety, shelf life
Electron beam treatment can inactivate pathogens in foods. E-beams could be applied to fish as a pasteurization/sterilization step without changing product temperature.
Early host response improves ESC resistance in channel catfish
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.
Kona-line SPF shrimp, Vibrio penaeicida candidates for bacterial challenge model
Juvenile SPF Kona-line shrimp were injected with V. penaeicida, causing significant disease, but certain bacterial concentrations allow survival long enough for additional testing.
Vitamins: Varied factors affect health, disease resistance effects in fish
Technical literature varies in reporting the ability of vitamins to improve fish survival and resistance to disease following infection with pathogens.
Prototype RAS raises larval penaeid shrimp
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.
Captive reproduction, larviculture of Florida pompano
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.
Hepatitis E an emerging foodborne illness
Although hepatitis E is infrequent in developed nations, additional cases may occur due to global travel patterns and importation of seafood.
Peracetic acid offers alternative sanitizing for seafood processors
Studies show that peracetic acid can reduce microorganisms on food products and effectively act against pathogenic and spoilage organisms.
New molecular techniques detect nodaviruses in Atlantic cod hatcheries
The nodaviruses that can infect the nervous systems of Atlantic cod threaten further expansion of the burgeoning cod-farming industry.
Green water culture of California halibut larvae
Although aquaculture offers potential for the production of California halibut, several aspects of production have yet to be optimized.
Finishing diet improves sea bream quality
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 and shellfish
Hepatitis A virus (HAV) is a widespread and serious foodborne pathogen commonly associated with shellfish-vectored outbreaks.
Achotines lab studies diets for larval, juvenile yellowfin tuna
Research at the Achotines Laboratory in Panama has been inconclusive involving probiotic treatments of first-feeding larval tuna and the rotifers they eat.
Pellet stability, hardness influence feed consumption of Pacific white shrimp
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.
