A new study on steelhead trout in Oregon offers genetic evidence that wild and hatchery fish are different at the DNA level, and that they can become different with surprising speed.

The research, published today in Nature Communications, found that after one generation of hatchery culture, the offspring of wild fish and first-generation hatchery fish differed in the activity of more than 700 genes…

Farmed Fish Consumption At Record High, UN Report Reveals, Guardian Uk (05-19-2014)
Humans have never eaten so much fish and other seafood, but nearly half of it is no longer caught wild but is grown in farms, says the United Nations. The rapid growth in the number of people living near coasts and fish farming’s ability to keep up with population growth has seen per capita fish consumption soar from 10kg per person in the 1960s to more than 19kg in 2012…
