Advances in yellowtail larval rearing
The University of the Canary Islands in Spain is researching yellowtail broodstock management and larval rearing to promote aquaculture diversification in Europe.
Brunei project develops technology for large black tiger shrimp production, part 4
Nutrition research run in conjunction with the breeding program ensures that cost-effective feeds are optimized for shrimp performance for a five-year project undertaken in Brunei Darussalam to develop advanced technology for production of large black tiger shrimp.
Oceanic institute achieves breakthroughs in culture technology for yellow tang
The culture of yellow tang represents a considerable economic opportunity and critical conservation strategy in coral reef ecosystem protection. The Oceanic Institute is working to establish aquaculture techniques to reduce the capture of wild fish.
Children’s hospital Boston makes zebrafish feeding regime breakthrough
Zebrafish offer a living model system for research in a wide variety of scientific disciplines. The Aquatic Resources Program at Children’s Hospital Boston recently identified an alternative feeding method that requires less labor.
Finishing diet strikes balance between feeding costs, tilapia fillet quality
In a study, tilapia were fed fish oil- or vegetable oil-based diets for five months, then switched to a fish oil finishing diet for three months. Growth and feeding efficiencies were not significantly compromised.
Realizing economic benefits from selective breeding
Although not universally practiced, the potential benefits of selective breeding in aquaculture outweigh all other options for improving animal performance. The genetic potential of aquaculture animals is plastic and can be improved over a relatively short timeframe.
Malaysia shrimp project scales up for production in biosecure biofloc modules
A large-scale integrated shrimp aquaculture park (iSHARP) project in Malaysia is approaching completion of its first phase. Biosecurity is a priority at iSHARP. The design of each unit allows individual modules or ponds to be “locked down” to prevent disease from spreading.
Dietary organic acids improve gut health, disease resistance in olive flounder
A study evaluated the effects of two organic acid blends on performance, gut health and disease resistance in olive flounder. The dietary organic acids were effective in lowering total gut bacterial counts, gut Vibrio counts and in conferring resistance against Edwardsiella tarda.
Phytogenic feed additives improve performance, antioxidants in rainbow trout
A study conducted to investigate the effects of encapsulated and non-encapsulated phytogenics derived from plants on the performance and antioxidant status of farmed rainbow trout.
Ich parasite serves as vector to transmit bacteria to fish
The authors used Ichthyophthirius multifiliis (ich) and fluorescent-tagged Edwardsiella ictaluri to examine whether parasites vector bacteria into fish.
Consumers’ salmon perceptions relate to consumption frequency
Consumer perceptions regarding seafood influence consumers’ willingness to consider and purchase fish as a viable protein choice.
Evaluating hybrid catfish egg quality
A significant correlation was established between ovarian fluid pH of stripped eggs and subsequent hatch of hybrid catfish eggs.
Arapaima a candidate for intensive freshwater culture
Arapaima, also known as pirarucu or paiche, offers appealing flesh color and texture, low fat content and high levels of protein and fatty acids.
Japanese eel aquaculture in Korea
After a decade of research, Korea has produced individual glass eels for Japanese eel aquaculture. Despite dependence upon the wild seed, Japanese eel aquaculture production has been growing significantly and comprises over 27 percent of Korea’s freshwater aquaculture.
Learning from tradition: Integrated aquaculture
Development of integrated aquaculture systems could assist in improving environmental quality and changing public perceptions of aquaculture.
Trial finds biomass harvest of cobia unaffected by stocking density in RAS
The establishment of land-based recirculating systems for cobia could expand production of the species. The authors, who demonstrated cobia are well suited for culture in tanks, conducted a study to compare the performance of cobia reared at different densities.
