I was hanging out looking to vulture roe off a group of Chinese fishermen. They were explaining how they make fish cakes from the fish and any reasonable fish is fine as they, from what I understood, puree the fish and add wine and something (language barrier) to give it consistency. They were very friendly and gave me the roe from their doe. They were bottom bouncing, but they were releasing everything they snagged outside of the mouth.
Hearing an explanation why these degraded fish were retained was interesting. Thumbs up to them for releasing all the snagged fish.
