Red abalone morphology
Red abalone-breeding programs need to consider total weight rather than shell length when broodstock animals are selected.
Black tiger domestication, selective breeding advance in Australia
Using clear-water tank systems, CSIRO and a collaborating farm have advanced the domestication of black tiger stocks in Australia.
Nucleotide supplementation improves survival, production of white shrimp, tilapia in trials
Several trials in Ecuador and Thailand showed that nucleotide supplementation in feed can improve growth and survival in shrimp and tilapia production.
Protein digestive capacity correlated with nutrient presence, availability in shrimp feeds
Shrimp diets need amino acid composition, balance and availability. Protein digestive capacity appears related to both nutrient availability and composition in feed.
Oyster farming in South Australia
Oyster farming in South Australia has become a highly productive and sustainable venture. A quality-control program, new grading systems and government support can help increase oyster exports.
Opportunities for rendered animal proteins in aquaculture feeds
Rendered animal proteins present viable alternatives to fishmeal in aquafeeds. High digestible protein and energy contents make them cost-efficient in low-fishmeal formulations.
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.
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.
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.
