Probably; I’m very suspicious of this stuff in my area because we have a lot of polluted waterways (with signs in three languages warning people not to eat the stuff) that always have people fishing in them. I understand fishing for sport, but too many of them are keeping their catch - and sometimes too much for one family to eat for a long time. I watch them using saltwater tackle for rivers, and realize they aren’t in it for sport...
I used to catch carp when I was younger (a nice fight), but you get sick of losing your rigs on shopping carts, tires & such (this is NJ).
A friend of mine went to the fish market in Tokyo- it’s the largest fish market in the world- you’d think it would have a fishy smell but it doesn’t at all. The Japanese know how to handle fish and how to keep the place clean. He said the market smells fresh.
