Hyper-intensive fish farming
High density fish aggregations represent new farming challenges regarding water quality and food distribution.
Zero water exchange
L. vannamei can be raised at high densities and zero water exchange with acceptable survival, growth and yields while minimizing water-borne diseases.
Necrosis due to WSSV can mimic YHV lesions in lymphoid organ of penaeid shrimp
Since severe lymphoid organ necrosis can also appear as a result of WSSV infection, do not use this type of lesion as the sole feature to diagnose YHV.
Impact of high-performance substrate technology on intensive commercial shrimp farm
Essentially, a substrate provides a high amount of a surface area that is readily colonized by bacteria and benthic algae, which behave as a huge biofilter.
Producing marine snails for biomedical research
The marine snail opisthobranch, a.k.a. the sea hare, is used for biomedical research in neuroscience as a model for memory and learning.
Liquid oxygen systems maintain dissolved oxygen levels
Low dissolved oxygen is associated with stressful conditions for shrimp. Liquid oxygen injection systems are a potential solution.
Shrimp breeding for low-protein or vegetable-protein diets unnecessary
Most shrimp cultured today are fed diets with greater than 30 percent protein, with much of this protein obtained from fishmeal.
WSSV scare in Australia
Australia’s prawn industry has encountered its first scare over white spot syndrome virus (WSSV) following positive test results in the northern territories.
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.
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.
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.
