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.
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.
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.
Effects of sterol supplements on shrimp growth, survival
A study found the quality and levels of sterol supplements in experimental feeds affected the growth performance of Pacific white shrimp.
Genetic improvement of Pacific oysters in Australia
The growing Pacific oyster culture industry in Australia is supported by cooperative research on genetic improvement and broodstock distribution.
Added carbohydrates aid production in extensive culture
Tank and pond trials in India confirmed that the addition of carbohydrates to extensive shrimp ponds helped increase yield and reduce inorganic nitrogen.
Selective breeding for shrimp: Adapting to multiple pathogens, intensive culture
Through selective breeding, genetic improvement programs can develop shrimp lines that exhibit commercially desirable traits like fast growth, disease resistance and overall hardiness.
Chemoattraction of low-molecular-weight compounds in shrimp feeds
The methodology used in a Texas Agricultural Experiment Station study provided a useful tool for evaluating the attractiveness of individual ingredients in prepared shrimp feeds.
Tracing origins, diversity loss in captive shrimp
Genetic diversity loss occurs in any stock of shrimp allowed to inbreed at random. Intentional inbreeding for performance traits accelerates rate of loss.
Potential of genetic selection for shrimp carcass, meat traits
Studies show variability for shrimp carcass and meat quality traits, especially fat quality. Selection for growth may lead to increase in yield.
Genetic improvement in aquaculture
Genetic improvements are designed to modify plants or animals for greater production performance in such targeted areas as growth or disease resistance.
Experimental microdiets for California halibut larvae
The successful replacement of live prey with microdiets for marine fish larvae is an important step in establishing effective aquaculture for the species.
