Commercial-scale RAS trial yields record shrimp production
A super-intensive, commercial-scale RAS trial with Pacific white shrimp at Oceanic Institute achieved record production at a low cost and with low stocking densities.
Pathogenic Vibrios in shellfish
It is important to understand the distribution of pathogenic bacteria in the marine environment to predict potential health concerns transmitted by seafood.
Screening probiotic bacteria for Atlantic cod larvae
The addition of probiotic bacteria to marine larvae can reduce pathogenic bacteria and subsequent infection by establishing a protective flora on the mucosal surfaces of the larvae.
Olive flounder culture in South Korea
The Republic of Korea is by far the top global producer of olive flounder raised mainly in flow-through systems at land-based facilities on the coast.
Probiotics found ineffective against Vibrio harveyi in limited-exchange shrimp pond survey
In a study, three probiotics applied to shrimp pond water throughout a culture period were not effective in preventing Vibrio harveyi outbreaks.
Gene-based markers could aid selective breeding
Stress hormone axes could be used as markers for selective breeding. Researchers see a negative correlation between weight gain and cortisol response to acute stress.
Managing pre-harvest off-flavors in pond-raised catfish
Although causes of pre-harvest off-flavors in catfish differ due to climate, water quality and pond hydrology, blue-green algae is a common culprit.
Blue shrimp quarantined in New Caledonia genetic variability program
To improve the sustainability of their breeding programs, shrimp producers in New Caledonia established a program with certified SPF blue shrimp.
UNC-Wilmington conducts research on black sea bass
Studies at UNC-Wilmington found that growth and survival of black sea bass larvae were improved through supplementation of DHA and ARA in live feed.
Quality parameters in farmed Atlantic salmon
Studies have identified changes in the quality parameters of farmed Atlantic salmon and wild salmon that reflect changes in the animals’ life cycles, diets and environments.
Seafood allergies: Control, prevention key to workplace management
Occupational seafood allergies can manifest as asthma, rhinitis, conjunctivitis, urticaria, and dermatitis. Anaphylactic reactions have also been reported.
Fishmeal replacements: Rendered protein meals effective
Research indicates that rendered protein meals could replace significant amounts of fishmeal in diets for shrimp and several cultured fish species without reducing weight gain.
Clay particles an alternative water treatment in marine fish larvae tanks
Clay particles present an alternative to water treatments with microalgae or algae paste in the culture water of marine fish larvae.
Low-salinity fish production technology can cut costs, aid biosecurity
Virginia Tech Aquaculture Research Group collaborated with MariCal to examine commercial feasibility of raising cobia in RAS under low-salinity conditions.
Feed preparation for white sea bass, totoaba broodstock
Hubbs-SeaWorld Research Institute and Universidad Autónoma de Baja California are working to produce improved broodstock diets for white sea bass and totoaba.
Marine fish stocking studies demonstrate species adaptability, environmental quality
Stocking marine fish in coastal impoundments in Florida, USA, has demonstrated improved habitat quality and given hatchery fish a transition to open water.
