Can I use Yellow Croaker for fish and chips?
Generally any non-oily fish is fine for deep frying. A relatively meaty fish (though not too meaty like monkfish) with a good thick fillet is best, because this allows the batter to cook without overcooking the fish. As Yellow Croaker is not an oily fish, you should be fine to batter and deep fry it provided you have a nice thick fillet.

Traditional fish and chips usually uses cod or haddock.
