Peamouth
Mylocheilus caurinus
Peamouth, also called peamouth chub, is a freshwater fish that Idaho Fish and Game lists as native to Idaho and places in the minnow family, Cyprinidae. Despite the agency's historical common-name synonym “redmouth sucker”, it is not classified there as a member of the sucker family. Brownlee Reservoir has a species-specific observation from 1994. This historical record does not establish current abundance, seasonal availability or permission to fish.
Brownlee Reservoir provides the reviewed still-water occurrence record. The source does not identify an individual bank, launch or capture depth.

Outland Atlas links Peamouth to water records in Idaho. These associations may reflect documented presence, seasonal runs, or historical stocking, not angler catch reports or current abundance. Read the linked water guides and source notes for evidence dates and reaches.
Peamouth Fishing Regulations & Limits
A recorded association does not establish that targeting or retaining Peamouth is permitted. Confirm current species protections, seasonal and emergency closures, reach-specific rules, gear restrictions, bag and size limits with the responsible fisheries authority before fishing. A fishing license does not override these restrictions. Outland Atlas's regulation records may be incomplete; missing rules do not mean unrestricted fishing.

Equipment planning for Peamouth
We have not selected a species-specific affiliate setup for this guide. First establish whether targeting is permitted at your destination; no tackle recommendation should be inferred from a species record.
A closed season prohibits targeting, even with release. Follow the water-specific rules linked in this guide.
- Check permitted methods, bait and hook restrictions before choosing tackle. Match rod, line and lure ratings to the lawful method and conditions, rather than buying by species name alone.
- Plan weather protection, drinking water and a way to call for help. For boat trips, confirm required flotation and safety equipment with the responsible boating authority.
- Read the habitat and water-specific source notes in this guide, then confirm an appropriate lawful method with the local fisheries authority before choosing equipment. Do not assume a general freshwater combo suits every species or water.
This is an editorial planning checklist, not hands-on product testing. Use equipment you already own when suitable. The gear directory contains affiliate links; any product suggestions below have their own disclosure. Retailer region, availability and Canadian shipping are not guaranteed.
