The Idaho species list, explained
How many Idaho fish have a page?
27 game fish from the IDFG Fishing Planner list; the five federally listed fish share one page.
Which IDFG source sets these Idaho bag limits?
The region blocks of Idaho Fishing Seasons and Rules, 2025-2027, as printed on IDFG Fishing Planner water pages.
Do limits change by region?
Yes; Idaho sets bag limits per IDFG region, so each species page prints every region it appears in.
Can I keep a bull trout?
No. 6 of the region blocks printed read bull trout catch-and-release, and USFWS lists bull trout as threatened.
Can I keep a sturgeon?
No. Sturgeon are catch-and-release in Idaho, and the Kootenai River white sturgeon is federally endangered.
Are steelhead and salmon covered?
Their pages name the waters IDFG lists and the permit rules in IDAPA 13.01.11; seasons are set by separate Commission proclamations.
Are state records listed?
Where a record list was readable, each species page prints the weight, water and date, never the angler.
A fish I target is missing; why?
It needs a place on the IDFG game fish list first.
