Life History:
		Pit sculpins are found predominately in streams with temperatures blow 25°C and oxygen levels near saturation. These waterways include fast rocky streams, spring fed creeks, and large boulder filled rivers. Pit sculpins are usually found in swift currents in riffles or runs. In some rare cases Pit sculpins may share habitat with marbled and rough sculpins, and they are often found in association with rainbow trout, speckled dace, and Sacramento suckers. Pit sculpins feed mostly on aquatic insects throughout the day and night and may become aggressive at times. Peak feeding is typically in the early morning. Pit sculpins become sexually mature in their second year and the age-class population decreases with every passing year. The sculpins spawn in February through early May with most breeding occurring in late February and March. Male sculpins develop dark breeding colors and an orange band on their dorsal fin. They entice female fish to lay eggs within their rock cave. Male pit sculpins may fertilize the eggs of several females. The fertilized eggs stick to the substrate within the caches and eventually larval sculpins hatch, though they remain close to the cave for some time.
