The fallfish (Semotilus corporalis) is a species of freshwater ray-finned fish in the family Leuciscidae. The fallfish is the largest minnow species native to Eastern North America.

Description

Average specimens generally measure about {{convert|5|in|cm|abbr=on}} in length, but individuals occasionally grow to {{cvt|15|in|cm}}{{cite web |title=Fallfish, Semotilus corporalis |url=https://www.unb.ca/research/institutes/cri/links/inlandfishesnb/Species/fallfish.html |last1=Curry|first1=Allen|last2=Gautreau|first2=Mark|last3=Yamazaki|first3=Gordon|website=Inland Fishes of New Brunswick |publisher=University of New Brunswick |access-date=2 December 2022}} with exceptional specimens of more than {{convert|19|in|cm|abbr=on}} having been recorded.{{cite web|last=Kirk|first=Molly|title=Jerry Hall Takes Over as Fallfish State Record Holder|url=https://dwr.virginia.gov/blog/jerry-hall-takes-over-as-fallfish-state-record-holder/|date=15 April 2021|access-date=2 December 2022|website=Notes from the Field Blog|publisher=Virginia Department of Wildlife Resources}} Juvenile fallfish have a dark stripe that runs down the center of their body. They are a silvery shade on the top and sides of the body, but have a white shading on the belly. Breeding males develop a pinkish tone on the opercular region, although the species does not develop bright breeding colors. Spawning males build stone nests, known as a redd, which form a prominent part of the bottom on many streams throughout the northeast. Spawning is communal with both males and females joining the nest builder.{{cite web |title=Fallfish |url=https://wildlife.state.nh.us/fishing/profiles/fallfish.html |website=state.nh.us |publisher=New Hampshire Fish and Game |access-date=2 December 2022}}

Distribution and habitat

Fallfish are found in the northeastern United States and eastern Canada, where they inhabit clear streams, lakes, and ponds. They predominantly prefer swift currents, however, they can also be found in well oxygenated pools. As their name suggests they are often found at the base of waterfalls. Before the introduction of fish such as smallmouth bass, largemouth bass, and brown trout, the fallfish was the apex predator in many streams.{{cite web |last1=Pinder |first1=Mike |title=Fallfish: Little Tarpon of the Commonwealth |url=https://dwr.virginia.gov/blog/fallfish-little-tarpon-of-the-commonwealth/ |date=27 September 2016|website=Notes from the Field Blog |publisher=Virginia Department of Wildlife Resources |access-date=2 December 2022}}

Diet and predation

Juvenile and young fallfish primarily consume chironomids and zooplankton. Once they reach 100mm their diet transitions to small fish (including their own young) and prey of opportunity such as fish eggs and terrestrial insects. There is little overlap between the diets of juvenile and adult fallfish.{{cite journal |last1=Johnson|first1=James H. |last2=Nack|first2=Christopher C. |last3=Chalupnicki|first3=Marc A.|title=Predation by Fallfish (Semotilus corporalis) on Pacific Salmon Eggs in the Salmon River, New York |doi=10.1016/j.jglr.2009.08.001 |journal=Journal of Great Lakes Research |volume=35|issue=4|pages=630–633|year=2009|bibcode=2009JGLR...35..630J |s2cid=84818688 }}

Angling

Fallfish are often encountered when fishing for more desirable species, but their large size, dogged fighting style, powerful runs on light tackle, and willingness to strike make them a worthy quarry in their own right. They will readily take bait, lures, and flies, and have been known to strike lures almost as large as themselves.

The International Game Fish Association (IGFA) All Tackle World Record for fallfish is {{cvt|1.62|kg|lboz}}, caught by Jonathan McNamara in the Susquehanna River near Owego, New York, USA on April 15, 2009. The record was tied on May 6, 2022, by angler Josh D. Dolin while fishing the Cowpasture River near Williamsville, Virginia. Two heavier, more recent, record fish from this river are currently pending,{{cite web |title=Fallfish (Semotilus corporalis)|url=https://igfa.org/member-services/world-record/common-name/Fallfish |website=IGFA.com |publisher=International Game Fish Association |access-date=16 May 2025}} which will take the record to {{cvt|1.81|kg|lb|order=flip}}. Previous records come from New Hampshire and Pennsylvania.{{citation needed|date=November 2022}}

Thoreau said of its eating qualities: "it tastes of brown paper, salted."
