Abstract

The Mottled Sculpin Cottus bairdii is found in cool to cold streams, creeks and rivers of northern North America (Page and Burr 1991). Sculpin are a benthic fish, living on the bottoms of the streams and rivers that they occupy. They reach 125 to 200 mm in total length when mature and can grow to 31mm-36mm by autumn of their first year of life (Ludwig and Normen 1969). Very little research has been conducted on the age and growth of C. bairdii and no comparative studies have been done examining the influence of elevation in their growth rates.
