Spotted BassDescription Anglers often confuse spotted/Kentucky bass with largemouth or smallmouth bass. It resembles both species, especially the largemouth, but the spotted bass is a lesser-known member of the black bass group of the sunfish family. Spotted bass have an elongated but moderately thick body, which enables fast swimming at short distances. Coloration is olive-green to brown on the back and upper sides and white on the lower sides and belly. There is a series of interconnected, diamond-shaped splotches along the lateral line that form a horizontal stripe from the eye to the tail fin. Below this stripe tiny spots form thin horizontal lines across the lower side and belly. There are two connected dorsal fins, the first with tiny spines and the second with soft rays. Eyes are an orangish-brown coloration and, at times, take on a red appearance. Two easy ways to tell the spotted and largemouth bass apart is that spotted bass have a sandpaper-like tooth patch on the tongue that largemouth bass lack, and the jaw of the spotted bass does not extend behind the eye, as it does on the largemouth bass. A spotted bass’ lips are often more abrasive than a largemouth’s, which anglers will notice when “lipping” the fish. Where They Live Spotted bass prefer clear, cool water, though they can survive in slower, warmer, and muddier waters than smallmouth bass. Compared to largemouth bass, their habitat requirements are more limited. Spotted bass are generally found in deeper waters than largemouth bass, and often congregate in schools along drop-offs, bluffs and brush piles at depths of 30 feet or more. They are also found along steep rocky banks, channel bends and rock dikes, preferably with some type of cover such as downed trees or rock piles. The ideal temperature for spotted bass is between 70 and 79 F and they can tolerate temperatures much lower and slightly higher. Because of their need for cool water, spotted bass cannot survive in farm ponds and other small impoundments where water temperatures can exceed 90 F. What They Eat Young spotted bass feed entirely on plankton, switching to insects and small invertebrates as they near adulthood. Adult spotted bass feed heavily upon crayfish, when available, followed by small fish, insects and insect larvae, frogs, worms, and grubs. Due to their preference for crayfish, spotted bass feed more often at or near the bottom, although they are know to chase large schools of shad and other baitfish near the surface or suspended well off the bottom. Like their largemouth and smallmouth relatives, spotted bass are ambush feeders, often hiding in or around cover until a vulnerable crayfish or prey fish swims by. To capture prey, spotted bass open their jaws, flare their gills and create a vacuum effect that sucks in the food source before it is swallowed whole. When They Spawn Spotted bass spawn mainly in river tributaries with gravel or mud bottoms and along rocky edges. They spawn in spring when water temperatures are between 63 and 68 F. Males make nests in colonies in mud or gravel bottoms by fanning silt away from their chosen nesting site with rapid movement of their tail fin. Nests have been recorded at relatively deep levels in some clear southern reservoirs (21 feet) and at very shallow levels in streams (10 inches). .
