As the Guardian article the OP shared and @Alex’s follow-up details, it’s important to learn about the sources of fish and seafood available to us.
By and large, US fisheries are quite well managed and provide good options for those of us in this country. For anyone looking for local fish and seafood options in the US or Canada, make sure to check out your options at https://finder.localcatch.org and filter by your criteria.
I’m lucky to live in an area of the country with good options (availability of local seafood far from the coasts is understandably sparse) and privileged that I can afford to participate in a weekly delivery of fresh fish caught by local fishers. Every week, I receive info about the fishers who caught that week’s fish, their fishing methods, which port their vessel brought the fish into and background on the fishery for that species.
Since the commercial salmon fisheries off California have been closed for a few years due to concerns of overfishing, the wild-caught Alaskan salmon we get is procured from companies that process and freeze salmon caught by local SoCal fishers (and others) that sail up to Alaska for the season.
Edited to add that not all the seafood I get is wild-caught. We’ve gotten locally farmed mussels, oysters, shrimp and abalone, all sustainably farmed.
