It's true. I grew up in a town with 500 fishing boats in Denmark. Today, there are about 30 left, and fishing is no longer an important aspect. I think it has major consequences for the whole community.
I would like to refer to Alert Bay, which was a first nation town that was totally dependent on fisheries, if we look back. I heard estimates that there used to be 10,000 years of fishing experience in that community. Today, there are about 500 years of fishing experience, which means 10-15 people are left who have experience in fishing. That's why I say the small communities are dying. The experience is being lost, and with it a way of life.
