That, and also aggressive overfishing.

A large part of traditional Swedish food is based on herring: Sill, pickled herring, is present on all the major holiday meals - Midsummer, Christmas and Easter.

There’s also the infamous Surströmming, fermented herring, of which there has been a shortage for several years now. While a small minority of the population, mostly older northerners, eat Surströmming, the loss of this tradition would be quite sad.

This is the best summary I could come up with:

Finns have been fishing for herring for generations, but new reduced EU quotas are threatening the traditional livelihoods of coastal communities.

Rising temperatures and falling salinity - itself due to increased rainfall and reduced inflow of water from the Atlantic Ocean - are threatening many species that are struggling to adapt.

“The more the Baltic Sea becomes a lake, the more harmful the situation will be for marine species,” explains Jukka Pönni, a researcher at the Finnish Natural Resources Institute (LUKE).

In the 1980s, the cod population reached record levels, but it has collapsed in the space of a few decades, to such an extent that the European Union has had to impose an emergency ban on its fishing in 2020.

“I eat herring every week,” Markku Karjalainen told AFP from the market square in the centre of Helsinki, which was teeming with people on an autumn weekday.

“The European fisheries policy dictated by Brussels should be completely overhauled”, insists the octogenarian, “and the tradition of the fishermen should be respected”.

No herring is a legit threat to old people in the Baltics. It’s one of those nasty national dishes that older generation would start take global warming seriously lol
