Hornyhead Chub Research Paper
Hornyhead chub
By: Nathan Ashton
Scientific Name: Nocomis biguttatus
Other Names: Redtail chub, Hornyhead chub
Size
Average Length: 11 centimeters (4.33 inches)
Maximum Length: 26 centimeters (10.23 inches)
(1 inch = 2.54 centimeters)
Average Weight: 21.2g
Habitat
Country Occurrence: Canada, United states
Hornyhead chub live in riffle/pool sections of small streams to medium sized rivers. Hornyhead Chub are sometimes found in dark-water streams, they are mainly found in clear-water streams though. Young Hornyhead chub use vegetation extensively for cover. This species is commonly found in water depths of 2 – 6 feet (60 – 181 cm)
Food
Hornyhead chub hunt when
Young Horneyhead Chub mainly eat water
fleas, small-crustaceans, small insect larvae, and algae. The adults include a lot more plant matter and algae along with larger aquatic insects, crayfish, snails, and small fish.
Predators
As far as we know, no one has studied predation of this fish. Others have suggested northern pike, rock bass, and smallmouth bass eat them. Humans do not usually consume this species, but it is frequently used as bait.
Reproduction
Sexual maturity is typically attained at 2 or 3 years of age. The hornyhead chub is part of a larger group of chubs that build dome-shaped nests of stones for spawning, usually from April until June, but extending into July in parts of Minnesota. A mile (1.6 km) section of stream can have several hundred nests. The male builds the nest after finding a suitable site. Describe in detail a three-step process of nest building, which is similar among Nocomis species. The 3 things Hornyhead chub´s do to build a nest are excavating (Digging)a concavity, forming a platform, and building a mound.
