 		"identification": "Perch family. A member of the perch family, very similar to walleye. Its best identifying marks are its spotted spiny dorsal. Its body colors are more of a dusky-brown to yellowish-olive, with large, irregular patches on its side, peppered in between with smaller dark markings and a white underside. Very slim build in comparison to walleye. Has a silvery, reflective eye similar to the walleye’s, and a mouth full of canine teeth. When handled, it flares out its gills, flattens its head and shivers as if bracing itself for the hook removal. Typically 10 to 19 inches."
