Park Species Detail: Britt, 1993: Semotilus corporalis , fallfish, (resident, native)The fallfish is found from Miramichi drainage in New Brunswick south to Virginia, with the Appalachians defining their western limit. They generally inhabit clear gravel bottomed streams and lakes. They are commonly found near cascades of falls. They are one of the largest cyprinids, reaching a size of 255 mm, with a maximum reported length of 508 mm, and can live up to 11 years. They are sexually mature between 2 to 4 years, with males being more precocious than females. In general the growth rate of males exceeds females after age 4. Fallfish are considered to be opportunistic feeders, they feed on algae, insect larvae, terrestrial insects, crustac~ans and fish. Spawning generally occurs in the spring when water temperature reaches 59 of. They spawn in the quiet waters of streams. A dominant male will build a nest by moving gravel and sand with his mouth and creating a mound which represents the nest. The dominant male then holds a central position on the nest and three to five females and other males spawn communally. Twenty or more fallfish may be associated with a single nest. Females lay as many as 15,000 eggs which become adhesive after fertilization. Eggs hatch in 138-144 hours at 63 of. Historically, fallfish have been collected in Rock Creek., Park Species Data Source: Britt et al 1993.
