Marginalized fish is a bit more expensive. Marginalized fish, also known as flounder, is a large family that includes several species, so it varies in price, with some being cheap and others being very expensive. Cheap ones cost less than $10 a pound, while expensive ones can reach about $100.

Crowfish are a bit cheaper, costing around $20-$30, and may be a bit cheaper during the season when they are available in large quantities and if they are closer to where they are caught. Crowfish is a particularly tasty sea fish, which used to be wrapped in dumplings to make sashimi and fried fish, but it's not very well preserved, and the meat will be crumbled when the fish is not fresh. When fishermen catch wild opium fish, they will first cut the tail to open the blood, so that it can be preserved for a longer period of time.
