Farmed Salmon Caught in Rivers Across Northwest Iceland

Escaped farmed salmon may be swimming in at least eight salmon fishing rivers in Northwest Iceland and the Westfjords. Farmed salmon pose a threat to the survival of wild salmon in Iceland. Two holes were found on a salmon farm net in Patreksfjörður in the Westfjords earlier this month. Authorities are conducting DNA analysis to determine whether fish caught in the rivers came from the Patreksfjörður farm.

Risk of genetic mixing

“Just in the last few days the reports have been pouring in and we seem to have at least eight confirmed cases, in eight different fishing areas, and that is a serious matter. And it remains to be confirmed through samples and research if or where these farmed salmon are from, but these are experienced anglers and guides who have handled these fish and it seems quite clear that this is the case,” Gunnar Örn Petersen, the CEO of The Federation of Icelandic River Owners (Landssamband veiðifélaga) told RÚV.

Gunnar says the salmon that have been caught are similar in size to those that were in the salmon farm in Patreksfjörður, though they could be fry that escaped from the sea pen in Arnarfjörður in 2021. He called the situation the environmental disaster that the federation has warned of since open-net fish farms began operating in Iceland.

“Whether we are talking about the diseases or massive death [of fish in the farms] or salmon lice beyond all limits and now it seems to be happening right here in front of your eyes that genetic mixing is happening. And genetic mixing is irreversible damage that no countermeasures can prevent and that we can’t reverse. It is therefore clear that open-net sea farming will be the final blow for Icelandic salmon stocks if the government doesn’t take the reins.” As many as 3,500 salmon may have escaped from the Patreksfjörður farm, which is owned by company Arctic Sea Farm.

Escaped salmon not unexpected, says fisheries spokesperson

Heiðrún Lind Marteinsdóttir, CEO of Fisheries Iceland, stated that escaped salmon in Icelandic rivers were “not unexpected. The fact that salmon enter a salmon fishing river does not mean genetic mixing,” she argued. “The fact that salmon mixes with wild salmon in some cases does not mean that the wild population is endangered. This has to be a sustained significant situation not just for a year but for decades,” she stated in a Kastljós interview.

Heiðrún says that the risk assessment of genetic mix states that the percentage of farmed salmon in Icelandic rivers can go up to 4% without endangering the wild salmon populations. According to Heiðrún, the percentage across Iceland is currently 0.09%. Gunnar Örn argued that the percentage of farmed salmon in some smaller rivers has, however, reached 4%, “and of course, we believe that those salmon stocks are also important.”
