Migration barriers protect indigenous brown trout (Salmo trutta) populations from introgression with stocked hatchery fish
Brown trout populations in the Belgian rivers Scheldt and Meuse have been intensively stocked in the past decades, often with material of uncertain origin. Moreover, the species habitat has become increasingly fragmented, preventing gene flow between neighboring populations. We assessed how this impacted genetic diversity and population structure by analyzing 12 wild populations (total n=309) and ...

Hatcheries, fish farms and such in the aquaculture industry require clean water to maintain a high survival rate while rearing aquatic animals. Contaminated water increases the risk of infection which in turn can compromise production. A common way to disinfect water is by generating ozone on-site with an ozone generator, which is commonly inside an ozone generator room. For human safety, the ...

Expanding marine protected areas to restore fisheries
After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...
