General Description
Members of the Mooneye family are moderately sized fishes with deep, flat-sided bodies covered by large silvery scales. They resemble herrings. They have large, reflective eyes with rods only, no cones. This makes them uniquely adapted to see under low light conditions but they cannot detect colors.

Diagnostic Characteristics
Large scales. Dorsal fin situated about the same distance posteriorly as the anal fin. Well-developed teeth on jaws, roof of mouth, and tongue.

Migration
May make extensive migrations to spawn in tributary streams.

Habitat
This is a species of the Large Valley and Large Prairie Rivers ecological systems, occasionally getting up into Medium prairie rivers and reservoirs that have direct connections; adapted to turbid water. Prefers calm waters for spawning and incubation.

Food Habits
Mostly insects; crustaceans, mollusks, and small fish also.

Ecology
Young of year goldeye in middle Missouri River prefer backwater and side channel pool habitats as rearing areas.

Reproductive Characteristics
Spawns from late March through May. Sex mature at 3-4 yrs. Spawns in schools, eggs semi-buoyant. Spawned first in May in middle Missouri River.

Stewardship Responsibility

Based on the Montana Natural Heritage Program's latest predicted habitat suitability model

Total species' range in Montana 89,290 km2 (23% of Montana)
Area predicted to have
some level of suitable habitat
12,751 km2 (3% of Montana)

Stewardship responsibility for 1-square mile hexagons intersecting predicted occupied stream reaches and standing water bodies is broken down as follows

  Total Suitable Suitable (native range)
Federal 18% 18%
State 5% 5%
Local <1% <1%
Conservation Lands/Easements 2% 2%
Private/Tribal/Unknown 75% 75%

See the Habitat Suitability for Biodiversity task in Map Viewer for a more detailed look at stewardship responsibilities within a variety of local jurisdictions.
