Hatchery International

As one of the largest oyster hatcheries on the East Coast, work at the Horn Point Laboratory Oyster Hatchery, part of the University of Maryland Center for Environmental Science, encompasses more than oyster...

Researchers at Roger Williams University’s Center for Economic and Environmental Development (CEED) have created standardized methods for breeding and raising more than 20 marine fish species in hu...

As recirculating aquaculture systems (RAS) become more advanced, controlling carbon dioxide (CO₂) levels is necessary for both fish health and system stability. Dissolved oxygen and ammonia control have always been important in RAS; however, high CO₂ levels are increasingly recognized as a limiting factor in intensive production environments.

Fish produce CO₂ as a norm...

University of Queensland PhD candidate Jessica Hintzche has created the most detailed genetic map for barramundi showing how traits can be passed between generations.

Barramundi farmers could potentially use this research to improve genetics in their broodstock and choose the sex that give the best traits.

“It’s also a step beyond genomic selection, allowing us ...

Proliferative kidney disease (PKD) is a disease of salmonids caused by a parasite (Tetracapsula bryosalmonae). The infection mainly triggers an excessive immune response, leading to renal hyperplasia and severe anemia. Contamination occurs throughout the year. When water temperature exceeds 9 °C (Gay et al., 2001), parasite spores are released by their host, a bryozo...
