Superior and Lake Erie. However, due to the large amount of pollution in Lake Erie the spoonhead population there is dwindling. The spoonhead is also a native Montana fish that can be found in the St. Mary and Waterton river drainages of Glacier National Park. They are generally found in fast flowing rivers and deep lakes. Habitat Spoonhead sculpins are found in fast flowing streams or in deep lakes. These fish prefer habitats that contain bedrock, boulder, cobble, rubble and logs to hide from their predators such as trout and other large lake fishes . Diet Not much is known about their diet but they most likely eat aquatic insects such as stoneflies and plankton. . These fish are prey to larger game fish such as northern pike, lake trout, and burbot. They can also be prey to mammals and birds if they are living in shallow water. Reproduction The spoonhead sculpin is sexually mature at two years of age when it gets to be about 7.0-8.0 cm in length. Spawning occurs in the fall when males will go out, find, and defend territories from other males. Once a territory is established the male will drive other males away from his territory, which includes a nest site. Males will select nest sites under rocks. Then they try to attract females with the quality of their territory and have the female lay her eggs and attach them to the undersurface of the rocks in the nest site. Then he drives the females away from the nests after he has fertilized them. Males can sometimes be polygynous but this is usually correlated to the male's size and to how many eggs he can guard at one time. The male will guard the nest until the eggs hatch, this generally happens 21 days after fertilization. Female fecundity ranges from 280 to 1200 eggs and is also correlated to female size.
