Advantages of aerated microbial reuse systems with balanced C:N, part 3
Aerated microbial reuse systems recycle nutrients in the form of organic detritus, which consists of aggregates of organic particles coated with a film of bacteria.
Lipid nutrition of Litopenaeus vannamei
Phospholipids and cholesterol are essential lipids for shrimp yet knowledge of dietary requirements during the juvenile stage is still limited.
Color of indoor tanks can affect stress and performance
Several studies now suggest the color of indoor aquaculture tanks should also be considered for improved animal health and performance in indoor systems.
Mesocosm systems for semi-intensive larval rearing of marine fish
In marine fish hatcheries, a mesocosm is a tank or pond in which a natural phytoplankton or zooplankton bloom is developed prior to stocking yolk-sac larvae.
Probiotic bacteria repress viral diseases in aquaculture
Probiotic bacteria may inhibit the migration of viruses among cultured fishes and strengthen their immune systems.
Irradiation: Expanding seafood’s safety arsenal
Irradiation is exposing food to controlled levels of ionizing radiation, killing microorganisms without changing texture, flavor or nutritional value.
High yields in Panama pilot trial on WSSV-infected farm
Results of this trial show it's possible to reestablish L. vannamei production in a WSSV-infected region, even with a continued viral source on the same farm.
Breeding shrimp for fast growth and virus resistance
Recent successes have proven that breeding shrimp for fast growth and virus resistance is both feasible and highly effective.
Shrimp hatcheries and the environment
As shrimp hatcheries continue replacing wild postlarvae, it is important to examine other areas of their operation that relate to the environment.
Improving shrimp stocks with microsatellites
Libraries have been produced from Pacific white shrimp containing many thousands of microsatellites, a source of potential markers for use in diverse applications.
General prophylaxis and quarantine of marine brood fish
Prophylaxis and quarantine are mandatory steps prior to maturation, spawning, larval rearing and fingerling production in a marine fish hatchery.
Sludge: An obstacle to shrimp health
Excess nutrients from poor feeding regimes result in accumulated sludge on the bottoms of shrimp ponds, harming the environment and animal health.
Raceway nursery production increases shrimp survival and yields in Ecuador
The use of intensive raceway nursery systems to produce juvenile shrimp under biosecure conditions is an important WSSV management tool.
Zero-exchange shrimp production: Success in WSSV-infected Panama
Results showed it is possible to grow shrimp in areas of Panama where WSSV is endemic, using biosecure, intensive systems.
Benefits of diagnostic monitoring
Diagnostic monitoring alone will not stop infectious diseases – effective vaccines and good husbandry and sanitary practices are also needed.
Shrimp immunity and disease control
Some lesser-understoood shrimp immune functions may become tools for improved disease control in the future.
