(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. the area in which the animal is naturally found, the region in which it is endemic. Possible predator on young trout and eggs (Miller 1952). It is being provided to meet the need for timely best science. In a dense population of sculpin in Montana, home range sizes were estimated at less than 50 meters and the longest movements were 180 meters. Most members of the Sculpin family are Northern Hemisphere saltwater fishes, but some species have adapted to living in fresh water. The mottled sculpin may be found in the northern one-fourth of Illinois. For queries involving invertebrates, contact Amy Benson. having more than one female as a mate at one time, breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. Spawning males are dark, often with an orangish edge to the first dorsal fin (p. 350).” Taxonomic Relationships: As Moyle (2002) states “Riffle sculpin … A field guide to freshwater fishes of North America north of Mexico. The mottled sculpin spawns in spring. The Animal Diversity Web team is excited to announce ADW Pocket Guides!

The type of bottom may be less important than the presence of cover, which can be gravel, stones, or submerged vegetation. Our objectives are to: Determine if mottled sculpin and mountain sucker are capable of colonizing sites post-disturbance; Evaluate factors affecting colonization for both species The buffalo sculpin has limited capability to change its color and shading to best match its surroundings. Their natural habitat range is from Northern Canada down to the Mobile and Tennessee River drainage systems. (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. 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. Table 1. Select from premium Sculpin of the highest quality. They may occur at densities of up to 5 per square meter. California Fish and Game 38:7-42. Mottled sculpin are very important intermediate predators in native aquatic ecosystems. (Froese, 2008), Average recorded lifespan in mottled sculpin is 2 years. Once inside the nest cavity, the female turns upside down so that she can release her eggs onto the cavity ceiling. 1993. Moyle (2002) does not mention this species from California. Mottled sculpin are very important intermediate predators in native aquatic ecosystems. They prefer areas with gravel or rocky bottoms with swift waters. Occasionally in lakes, reservoirs, or springs in rocky substrate. Males then remain in the nest cavities until the eggs hatch and the young fish leave the nest a few weeks after hatching. (Becker, 1983), Based on courtship behaviors, visual and tactile cues are likely to be used by mottled sculpin in communication. They can be found at up to 16 meters depth. Therefore, we propose to compare factors influencing colonization of mottled sculpin (Cottus bairdii) and mountain sucker (C. platyrhynchus) in the Wyoming Range. Miller, R.R.

National Science Foundation 1993; Moyle 2002). Adults occur in rubble and gravel riffles, less often in sand-gravel runs of headwaters, creeks and small rivers. The mottled sculpin thrives in clean headwaters, the sources and origins of our streams and rivers, and is listed as a species in the greatest need of conservation on the Illinois Wildlife Action Plan. Minckley, W.L. The male prepares a nest under a rock and stays with the eggs and young until they leave the nest. Found in central and eastern Canada as far west as Manitoba, and in Labrador. Healthy mottled sculpin populations are used as an indicator of healthy trout populations because they are important prey of trout. The color and band on their dorsal fin is probably also involved in courtship, as it only appears during the breeding season. 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. North Carolina Wildlife Resources Commission. It is often found in cold-water habitats, such as streams that receive water from springs. They are benthic ambush predators, consuming primarily aquatic insect larvae (e.g., flies and midges), crustaceans, small fishes, and fish eggs (Etnier and Starnes 1993). Their generic name, Cottus, is from an old European name for sculpin. The mottled sculpin, Cottus bairdii, is known to inhabit a large geographical range in North America. Mottled Sculpins are generally found in gravel or rocky rubble substrates in swift waters of headwaters, creeks, and small rivers.

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). 1998, 10294).Feed mainly on aquatic insect larvae, but also on crustaceans, annelids, fishes, fish eggs, and plant material (Ref. However, introduced round gobies may dramatically effect mottled sculpin populations through predation and competition. Disclaimer: They eat aquatic insects, plant material, and even other sculpins, and are in turn eaten by other fish species. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). Mottled sculpin are hosts for the larvae of some native clam species, including cylindrical papershells and slippershell mussels. "fishbase.org" Males attract females to their nests, where the females remain for a few days and lay their eggs. 1998).

Houghton Mifflin Company, Boston, MA. Becker, G. 1983. (Becker, 1983), Male mottled sculpin use courtship movements to attract females to their nest cavities. Largest size I've seen is about … 1979. Outside of the breeding season mottled sculpin are not aggressive and can often be seen near or next to each other. They begin breeding at about two years of age. 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 male's head and fins then become jet black and his body becomes pale. 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. Original spelling end with ii (Nelson et al. reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body. They may also help trout populations through their predation on stoneflies, which each trout eggs and young. having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect. Eggs hatch in about 17 days and young depart from the nest about 14 days after that. Contact us if you are using data from this site for a publication to make sure the data are being used appropriately and for potential co-authorship if warranted. In Michigan trout streams, one of the main predators ofbenthic invertebrates is the mottled sculpin (Cottus bairdi) whose diet and selective predation may.influence benthic invertebrate community structure. Fish culture in fisheries management. Also found in springs and their effluents and rocky shores of lakes (Ref. Taxon Information Mottled sculpin have a lateral line system that helps them to perceive water movements and pressure changes. The male accompanies the female into the cavity and arranges himself next to her. They prey on small aquatic animals, mostly invertebrates, and form an important prey base for larger fish, such as brook trout and northern pike. 1998, 10294).Spawn in the spring (Ref. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. In contrast, Starnes (personal communication) believes that records of this species in the Broad drainage in North Carolina may have been the result of stream capture from the French Broad and is thus native. Mottled sculpin have been reported as prey by brook trout, brown trout, northern pike, common mergansers, and water snakes. Mottled sculpin are found in areas with fast water movement, their flattened body shape helps them to take refuge from fast currents among the rocks and debris along the bottom. Females reach maturity when as small as 55mm long, but most individuals become mature when about 75 mm long. (Becker, 1983; Froese, 2008), Mottled sculpin are small, stout fish with relatively flattened bodies. (Becker, 1983), Mottled sculpin populations are not considered threatened currently. 1952.
