Moxostoma hubbsi

Copper redhorse is a ray-finned fish in the family Catostomidae (order Cypriniformes) — Moxostoma hubbsi, recorded as Endangered.

Status
Endangered
Scientific name
Moxostoma hubbsi
Taxonomy
Cypriniformes · Catostomidae · Moxostoma

Appearance

The operculum's gill rakers are medium in size and widely spaced, and there's 18-19 of them. The copper redhorse only has 1 dorsal fin that has 13- 14 rays. The caudal fin is abdominal, wide, is rounded and has 9-10 rays.

The species ranges from 40.64 to 45.72 cm (16 to 18 in). It is compressed laterally, with the back forming a huge arch that forms a humpback shape.

Range and habitat

The copper redhorse occurs primarily in medium-sized rivers where water temperatures exceed 20 °C in summer. Spawning occurs in riffle areas where the current is moderate to slow and the depth ranges between 0.75 and 2 m, over fine to coarse gravel and cobble substrate. To date, there are only two known spawning grounds (Chambly archipelago and the channel downstream from the Saint-Ours dam) and a nursery area (Saint-Marc-sur-Richelieu) has been identified in the Richelieu River.

In crisis

Confirmed populations currently exist in the St. The population is aging and recruitment is extremely low. The total number of mature individuals appears to be several thousand at the most.

Copper redhorse is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
