Waters (1975) reported that no trout eggs or fry were ever found in stomachs of the slimy sculpin, Cottus cognatus, in \Ialley Creek, t~innesota. Results from this study indicate the slimy sculpin is a suitable fish species for monitoring rivers that receive multiple industrial and municipal effluents. They are intolerant of impaired water qualities. Because it is so difficult to study deepwater sculpin, little is known about their mating systems. Google Scholar. From the evi de nee then, 1-1e know that scul pins prey on trout and sa 1mon fry in the wild environment. 1976. The influence of acidic runoff episodes on slimy sculpin reproduction in Stone Run. Google Scholar. Reproduction. Karlstrom O. Incomplete lateral line ends under soft dorsal fin. The responses of slimy sculpin and white sucker differed, perhaps in relation to differences in life history characteristics. 27843), presumably moving to and from fresh water, at least for spawning (Ref. Mottled brown with dark blotches over entire body and fins. Slimy Sculpin (Cottus cognatus) General Information Sculpins prefer high gradient waters with rock, gravel substrate, which limits their distribution to the northern waters of the state. In North America, it occurs from Zoon, 4: 53–63. whether slimy sculpin would spawn in the study. Identification. The sculpin were found to be less active and have lower rates of reproduction when found in these waters. Slimy Sculpin Reproduction 385 Fecundity was determined for slimy sculpins col lected near Olcott and Nine Mile Point, New York during April to May in 1989, 1991, and 1993. The sculpin were found to be less active and have lower rates of reproduction when found in these waters. Slimy sculpin reproduction.—T o determine. 27547).In some areas, they are common in brackish water (Ref. Three pelvic fin rays. Margin of first dorsal fin normally clear, but turns bright red in spawning males. This project will use genetic testing to explore the survival and reproduction rates of slimy sculpin (Cottus cognatus, a small, bottom-dwelling forage fish) translocated into several southern Minnesota streams. However, scul pins are also prey for brown trout (Jones 1972; Gard and Fl ittner Transactions of the American Fisheries Society, 130: 1106–1115. The slimy sculpin has been studied in waters where there is current acidification (water that is more acidic). Slimy Sculpin (Cottus cognatus) - Native. Inhabits rocky riffles of cold streams, rocky areas of lakes (commonly at 90-106 m depth), springs and their effluents (Ref. A 3-inch adult slimy sculpin. Quantitative methods in electrical fishings in Swedish salmon rivers. The slimy sculpin has been studied in waters where there is current acidification (water that is more acidic).
