Bluehead Chub: Facts & Habitat

About Bluehead Chub

The bluehead chub (Nocomis leptocephalus) is a species of freshwater fish belonging to the family Leuciscidae, the shiners, daces and minnows. native to North America. Its name is due to its appearance, as breeding males have a blue head and develop large nuptial tubercles. Adult bluehead chubs are, on average, between 70 and 160 mm (2.8 and 6.3 in) in length. They have a robust body with uniformly large scales. The scales are present on the belly and breast. They have a pored body, a weakly falcate pectoral fin, and pharyngeal teeth. They have a large mouth, small eyes, and a terminal barbel. Other characteristics include a darkened lateral band, spot on the caudal fin, and red coloration of the fins and iris of the eyes. They have 40 lateral line scales and 8 anal rays. The bluehead chub is a freshwater fish, and lives in pools, rivers, and streams. They feed on insects and plants.

Habitat

Bluehead chubs inhabit freshwater pools, creeks, and small to medium rivers with sandy or rocky bottoms. They live in warm to cool waters that have swift currents and are usually turbid.

Reproduction and life cycle

Bluehead chubs spawn in the spring and reproduce by external fertilization in which the female releases eggs onto the bottom and the male releases milt to fertilize the eggs. The male makes a nest of gravel in a mound for the female to deposit the eggs. After fertilization, the male guards the eggs until they hatch. They mature for three years before reaching reproductive maturity.

Distribution

The bluehead chub is native to the United States and can be found in the southeastern United States. It is distributed throughout the York River system of Virginia, the Atlantic and Gulf coast drainage, and the lower Mississippi River drainage into Mississippi and Louisiana. Its range includes Virginia, West Virginia, Alabama, Mississippi, North Carolina, Florida and Louisiana. As a result of bait bucket releases by fishermen, the bluehead chub has spread to multiple drainage basins in which it is not native.

Etymology

The genus name Nocomis comes from the Native American name for "grandmother".

Diet and feeding

The FishTraits compilation records these diet categories for this species: algae or phytoplankton; aquatic or other vascular plants; detritus or unidentified plant material; invertebrates or larval fish; larger animal prey (a source category covering fish, crayfish, crabs, or frogs). These are broad categories, not a claim that every individual consumes every example in a category.

Reported feeding positions include bottom feeding and surface or water-column feeding. The compilation combines published observations; diets can vary with age, locality, and available food.

Habitat preferences

Reported habitat associations include medium to large rivers, streams and small rivers, creeks.

The source records associations with clay or silt, sand, gravel, cobble, boulders, bedrock. An association indicates reported use, rather than an exclusive requirement.

Reproduction and parental care

The compilation reports a representative maturity age of 1.5 years. Its maturity field summarizes mean, median, or modal estimates, usually for females; male estimates can be used when female data are unavailable. It is not a fixed age at which every fish first breeds.

Batch or serial spawning has been reported somewhere in the species’ range. This does not establish the same spawning pattern for every population.

Recorded spawning months are May, Jun for the source’s reporting region (VA). This is a regional calendar, not a range-wide schedule.

The reproductive-guild classification includes guarding eggs or young at a spawning substrate or nest.

Size and recorded longevity

FishTraits reports a maximum total length of 26 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.

Recorded longevity in the compilation is 2.5 years. Wild observations were preferred, but captive records were accepted where wild records were unavailable, and unspecified records were assumed wild. The value is not a guaranteed wild lifespan or an aquarium life expectancy.

Where it lives

31.7%of mapped records

Share of 9,253 GBIF observation records with a state location, across 12 states. The orange dots are USGS stream-survey sites where this species was caught.

A blank area on the dot layer usually means nobody sampled there, not that the fish is absent. Turn on “every survey site” to see where the survey looked.

Share of records by state

The USGS stream survey caught it at 1,028 of its sites, in 9 states. That survey and the GBIF records are two different counts of two different things, so the site keeps them apart.
