Development of edible vaccines for aquaculture
Scientists are developing edible vaccines for the animal healthcare market that can be delivered directly through corn grain.
Biosecurity and closed recirculating systems
Effective biosecurity requires environmental isolation in a closed system, like RAS, to culture cephalopod species (squid, cuttlefish and octopus).
Efficacy of probiotics in grow-out systems
An aquaculture probiotic is a bacterial supplement to manipulate microbial communities in the water and to improve growth and survival of the cultured species.
Carotenoid supplements and WSSV
The effectiveness of carotenoid supplements will depend upon the severity of infection and other stress factors that affect the condition of the shrimp.
Shrimp production and quality assurance in Thailand
Thai shrimp processors worked very hard to raise their standards in order to be competitive in the world market.
Initial evaluation of shrimp vitamin requirements in laboratory tanks without water exchange
Only a few studies have been conducted with a few species. Shrimp vitamin requirements are simply trace amounts for maintenance metabolism and growth.
Culture of Penaeus vannamei in single-phase and three-phase recirculating aquaculture systems
A series of paired production trials evaluated single-phase and three-phase recirculating systems stocked with high health postlarvae.
Recirculating and static shrimp culture systems
The static shrimp culture system did not negatively affect survival and had a positive effect on growth compared to the recirculating culture system.
Zero exchange, aerobic, heterotrophic systems: key considerations
Most environmental concerns about aquaculture practices can be addressed effectively by zero exchange, aerobic, heterotrophic culture systems.
Shrimp viruses: The urgent need for research
Shrimp viruses have been the etiological agents most responsible for devastating losses, and no country with a significant shrimp farming industry has escaped.
Risks associated with chemicals and other agents used in attempts to control White Spot Syndrome Virus
Shrimp farmers in Asia and the Americas have used chemical and biological agents to control White Spot Syndrome Virus (WSSV) disease.
Benefits of a microbially dominated intensive shrimp production system
Researchers at the Oceanic Institute studied the effects of pond water on the biology of Pacific white shrimp (Litopenaeus vannamei).
Role of bacteria on nutritional and management strategies in aquaculture systems
Bacteria play a role in the dynamics of nutrients in aquaculture production systems. This article explores the role of bacteria on nitrogen.
Value-adding begins with ‘E’
Vitamin E, or alpha-tocopherol, is crucial to fish defense against lipid-oxidising free radicals. It also has great impact on flesh quality.
Physiological role of dietary vitamin C in penaeid shrimp
Penaeid shrimp require dietary vitamin C for maximum growth and survival. In the 1970s, a vitamin C deficiency disease was described.
Proactive disease management in shrimp
Proactive shrimp disease management, or prevention, is preferable to reactive treatment. Prevention can, however, can be costlier in the short term.
