You should consider yourself lucky, its a very good picture. You can even count the spines on the dorsal and anal fins. Thats key in IDing many fish. In college I learned how to ID dead fish only. My prof. said color does not matter with fish identification. External features like fins, mouth, eyes, scales...thats how you gotta ID a fish. Take bluegill for example, most people look for the blue on the gills...its not there when dead. What is there is a dark spot on the soft dorsal.
