My wife and I moved from Hawaii to south carolina and she was astounded to see wrasses we used as bait while fishing going for $50+ at the store. I explained that catching the fish is the easy part. But doing it so the fish is uninjured is harder. Its way easier to spear a fish or hook it than it is toncatch it in a net. Then you have to keep it alive until you can get it to a holding facility and sell it to say a distributor. They're going to hold it and ship it to a wholesaler in say LA, who is going to in turn sell it to your lfs. And every step in the chain not only has to make up for losses,but also make a profit, so there's a healthy markup at every step of the way. So that $50 fish probably netted the guy who caught it $2.
