Fisher hunters trying to round up 300,000 runaway salmon that escaped Norwegian breeding farms into rivers

ABC News –

Fish hunters in Norway are trying to round up as many of the hundreds of thousands of salmon that have escaped breeding facilities this year as they can, and an organization is spending a pretty penny toward those efforts.

Nearly 300,000 runaway salmon have left the farms and filtered into Norwegian rivers, according to OURO, the country’s aquaculture industry association for escaped fish, which is tasked with capturing them.

Divers use harpoons to pluck the fish out of the water.

When fish kept in pens escape into connected bodies of water, it can affect wild populations as they compete for food and spawning partners, according to Seafood Watch, an information website run by the Monterey Bay Aquarium in California.

Fish farmed in non-native areas can establish themselves as an invasive species and disrupt the ecosystem.

In addition, when farmed species, which are “distinctly different from their wild cousins,” breed with wild species, the genetic makeup of the offspring may be less suited to surviving in the wild, according to Seafood Watch.
