Study: Quieter hatcheries improve Chinook salmon return rates
A study found hatchery noise may reduce Chinook salmon survival, with quieter conditions improving return rates to spawn.

Is a ‘baby food’ bottleneck looming for aquaculture?
Global aquaculture, particularly farmed shrimp, depends on artemia for hatchery feeds. Supplies meet current needs, but growth will require alternatives.

India’s shrimp industry adapts to COVID-19 restrictions
A look at trends in various segments of the shrimp production supply chain in India – hatcheries, farms, feeds and exports – amid COVID-19 restrictions.

Efficacy of natural products and antibiotics in shrimp hatcheries
This study evaluated through in vitro analyses the antimicrobial effectiveness of natural products used for P. vannamei bacterial diseases and antibiotics against pathogenic Vibrio strains circulating in Ecuadorian hatcheries.

Stirling researchers identify viable ablation alternatives for shrimp hatcheries
A research project aimed at improving shrimp hatcheries’ welfare practices shows there is a viable alternative to a common spawn-inducing technique.

Treatment of shrimp hatchery effluents
Shrimp hatcheries are highly dependent on continuous availability of clean water and proper treatment of effluents using sedimentation and biofiltration.

A study of Zoea-2 Syndrome in hatcheries in India, part 3
In this third and final part, authors present recommendations to help reduce the incidence of Zoea-2 Syndrome, which is not caused by any known infectious agents in P. vannamei hatcheries in India.

A study of Zoea-2 Syndrome in hatcheries in India, part 2
Indian shrimp hatcheries have experienced larval mortality in the zoea-2 stage, with molt deterioration and resulting in heavy mortality. Authors considered biotic and abiotic factors. Part 2 describes results of their study.

For Great Lakes aquaculture, it’s a tale of two countries
Canada and the United States may be friendly neighbors, but when it comes to aquaculture, the bordering countries take vastly different approaches to aquaculture in the Great Lakes.

Aquaculture Exchange: Barry Costa-Pierce, UNE
University of New England Professor Barry Costa-Pierce says aquaculture is often neglected in studies examining ocean health and ecosystem and resource management. The “Ocean Prosperity Roadmap” released this summer, he said, was more of the same.

Why do we feed shrimp the way we do?
The potential shrimp aquaculture has for significant improvements in performance through improved genetics and nutrition will not be fully expressed unless appropriate feeding methods are practiced.

ASAIM addresses challenges to growth of marine fish farming in Southeast Asia
In its efforts to advance sustainable aquaculture practices and the use of soy-based feeds in Southeast Asia, the American Soybean Association International Marketing Program (USAIM) has identified several challenges.

Production priorities overshadow genetic quality at African fish hatcheries
African fish hatcheries were built to produce catfish and tilapia fingerlings, but practices that fail to maintain genetic diversity limit growth performance.
Responsibility
No-maintenance filtration for hatcheries
A properly designed fluidized-bed filtration system increases hatchery output by providing a chemically stable, high-quality water supply.
