What kind of fish is good for stew?

Crucian carp, catfish.

As for the whole fish, crucian carp is the best in soup, and it is difficult to compare with other fish. The only ones that can fight it out are puffer fish and other poisonous fish, but the price risk is there. . . Silver carp heads can be used to make soup, but other parts are really useless and are generally used for pickling and storage. The fish (yellow duck fish) is second only to the crucian carp and puffer fish. The soup tastes good, but the meat is less and tighter, and it cannot be melted at all.
