Mottled sculpin are widespread in North America, with a broadly disjunct range. (Becker, 1983; Froese, 2008), Mottled sculpin are found in gravel bottoms and sandy riffles of small headwaters, streams, and small rivers or in rocky shoreline areas of lakes, including the Great Lakes. The type of bottom may be less important than the presence of cover, which can be gravel, stones, or submerged vegetation. For queries involving invertebrates, contact Amy Benson.

They take refuge during the day under rocks or vegetation. 227 pp. They have round snouts and are cryptically colored, with brown to black mottling on their backs, sides, and fins and whitish bellies. reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body. (Becker, 1983), Mottled sculpin egg development depends on water temperature, at temperatures of 11 to 13 degrees Celsius eggs hatched in 17 days. There is a disjunct population in Missouri and a large western population in the northern Rocky Mountain states, from British … There is a small black spot on the first part of the first dorsal fin, which helps to distinguish them from round gobies, and a larger spot on the back of the first dorsal fin. They may also help trout populations through their predation on stoneflies, which each trout eggs and young. The mottled sculpin (Cottus bairdi) lives primarily in shallow, cold water throughout Yellowstone, but it is also found in the Yellowstone River above the Lower Falls and in Yellowstone Lake. Some have regarded them as serious predators of trout eggs, but research suggests that their predation on trout eggs is usually on drifting eggs that won't develop anyway. Mottled sculpin are very important intermediate predators in native aquatic ecosystems. Etnier, D.A., and W.C. Starnes. (Becker, 1983). North Carolina Wildlife Resources Commission. They do not have obvious scales, although they have a line of small prickle-like scales below their lateral line, which is incomplete and ends just under the second dorsal fin. (Becker, 1983), Mottled sculpin populations are not considered threatened currently. Lea and J.D. The fish was introduced accidently into Colorado by the Colorado Division of Wildlife (Zuckerman and Behnke 1986); the pathway of introduction is unknown for North Carolina. They shake their heads, raise their gills, and undulate their bodies to get the attention of females. The Animal Diversity Web team is excited to announce ADW Pocket Guides! Mottled sculpin are very important intermediate predators in native aquatic ecosystems. The vertebrates of Arizona, part 2. animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature, fertilization takes place outside the female's body. Also found in springs and their effluents and rocky shores of lakes (Ref. University of Arizona Press, Tucson, AZ. (On-line). While considered to have a wide range of habitat preferences, the presence of mottled sculpins is a sign of good water quality. Tanya Dewey (author), Animal Diversity Web.

In eastern North America it occurs in the Arctic, Atlantic, and Mississippi River basins from Labrador and northern Quebec west to western Manitoba, and south to the Roanoke River drainage, Virginia, and the Tennessee River drainage, northern Georgia and … (1987) found mottled sculpin to have an estimated home range of 12.9 m. Greenberg and Holtzman (1987) found the maximum home range of the banded sculpin Cottus carolinae to be 47 m2. Columbia Mottled Sculpins inhabit river pools in rocky areas below riffles where they disperse to no more than a few hundred metres, only to move back into faster current during the reproductive season. Mottled sculpin are more active at night, feeding in more open areas. Native Range: This species has a broad distribution, with disjunct eastern and western populations. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. Synapomorphy of the Bilateria. 2004. Menhinick (1991) listed this species as probably introduced to the Broad River drainage.

Sexual maturity is reached at adult sizes of 59.2 mm in males and 53.1 mm in females, sizes that can be reached within a year of hatching. Mottled sculpin have been demonstrated to have a positive effect on trout populations through preying on stoneflies, which prey on trout young and eggs, and because they are important prey for large trout. However, introduced round gobies may dramatically effect mottled sculpin populations through predation and competition. The mottled sculpin is distributed discontinuously throughout much of North America, from Savannah, Mobile and Tennessee River drainages in Georgia and Alabama, north to Canada, and disjunct populations in Missouri, Arkansas, Utah, and New Mexico (Lee et al 1981). They are also commonly found in streams in the Rocky Mountains along with many streams found throughout the Midwest United States. The male's head and fins then become jet black and his body becomes pale.

(Becker, 1983; Froese, 2008), Mottled sculpin are small, stout fish with relatively flattened bodies. Therefore, we propose to compare factors influencing colonization of mottled sculpin (Cottus bairdii) and mountain sucker (C. platyrhynchus) in the Wyoming Range. They may also help trout populations through their predation on stoneflies, which each trout eggs and young. There is a disjunct population in Missouri and a large western population in the northern Rocky Mountain states, from British Columbia and Alberta south to southern Nevada and northern New Mexico. Their generic name, Cottus, is from an old European name for sculpin. The color and band on their dorsal fin is probably also involved in courtship, as it only appears during the breeding season. not only impact the species involved, but can also have a wide range of direct and indirect effects that resonate throughout the community. Mottled sculpin have been reported as prey by brook trout, brown trout, northern pike, common mergansers, and water snakes. They prey on small aquatic animals, mostly invertebrates, and form an important prey base for larger fish, such as brook trout and northern pike. 1979. offspring are produced in more than one group (litters, clutches, etc.) Eggs hatch in about 17 days and young depart from the nest about 14 days after that.

Bait bucket release in the Colorado River in Arizona, California, and Nevada. Mottled Sculpin lives in cooler streams in riffles or in rubble-bottom areas in lakes. Once inside the nest cavity, the female turns upside down so that she can release her eggs onto the cavity ceiling. 2004). movements of a hard surface that are produced by animals as signals to others. Healthy populations of mottled sculpin are used as an indicator of healthy trout populations, which are very important gamefish. Mottled sculpin may compete directly with round gobies, an invasive species in the Great Lakes. Mottled sculpin are found in gravel bottoms and sandy riffles of small headwaters, streams, and small rivers or in rocky shoreline areas of lakes, including the Great Lakes. (Becker, 1983), Mottled sculpin eat mainly aquatic insect larvae, such as mayfly nymphs, caddisfly larvae, stonefly larvae and midges, but also eat small crustaceans, such as amphipods, copepods, and ostracods, they also eat leeches, smaller fish, fish eggs, and some aquatic plant material and algae. Freshwater sculpins rarely exceed 7 inches in length, while the majority are considerably smaller, and they inhabit virtually every kind of habitat in which you’d also find trout, salmon, and smallmouth bass: from rocky, cool headwater streams, to lakes, to rocky areas of slower, meandering lowland rivers.
