Determining ion concentrations for Litopenaeus vannamei culture in freshwater
Future increases in U.S. shrimp farming are likely to be inland, which entails the use of ground waters with an ion concentration vastly different from seawater.
Freshwater trial with Litopenaeus vannamei leads to further stocking in Panama
Panama shrimp farmers looking to boost production in the presence of White Spot Syndrome Virus have tried various strategies, including freshwater systems.
Honduras hatchery uses recirculation systems for shrimp broodstock maturation
Although three Honduras hatcheries have shrimp postlarvae maturation units, only GML of Seafarm International has achieved consistent production with recirculation.
Advanced conditioning systems for marine fish broodstock
To be successfully conditioned to spawn in captivity, most marine fish species must be exposed to temperature and light cycles that mimic their seasonal changes in nature.
Tasteless smoke: Emerging processing technology
"Tasteless smoke” – a purified extract of wood smoke with particulate matter removed – has a mystifying ring to it, but is a straightforward concept.
Dietary protein level and protein/energy ratios for optimum growth of olive flounders
Olive flounders fed a diet containing 45 percent crude protein at 4,000 kcal/kg appeared to utilize feed more efficiently than fish fed the other diets.
Genetically male vs. mixed-sex Nile tilapia performance compared in RAS
A promising strain of Nile tilapia is the genetically male tilapia that results from the mating of sex-reversed female fingerlings with normal females.
Pink shrimp hatchery production in Florida
The authors developed hatchery techniques for producing Florida’s native pink shrimp for the Crystal River Mariculture Center.
Effect of post-spawning feeding on reproduction in channel catfish
Feeding channel catfish broodstock once a week to satiation limited fish growth but resulted in optimum condition factor during the post-spawning phase.
SPF line of Penaeus chinensis shrimp under development
Institutions in China and the U.S. are establishing domesticated lines of Penaeus chinensis, a cold-tolerant species with additional positive production characteristics.
Catfish genetics and breeding
Although research on catfish genetics began in the 1960s, applications of genetic improvement in aquaculture have lagged behind other animal industries.
Catfish of tomorrow
Catfish producers and processors should actively begin the process of reconsidering production systems to drastically reduce costs and equitably share risks.
Wild versus domesticated: A TSV-resistance comparison
Taura Syndrome Virus has negatively affected Guatemala's shrimp-farming industry, reducing overall shrimp survival from 81 percent to 30 percent.
Temperature effects on shrimp survival to disease
A number of studies have demonstrated the role of a temperature-mediated component in shrimp survival to infection by White Spot Syndrome Virus.
Genetic advances with fleshy shrimp in China
The Yellow Sea Fisheries Research Institute in Qingdao, China, is producing strains of fleshy shrimp with faster growth rates and higher disease resistance.
Selective breeding essential for further productivity, sustainability in aquaculture
If selective breeding is done for several traits simultaneously, the selection response for each will be reduced, as compared to single-trait selection.
