what is the smallest bass u can keep


It depends on the region you are fishing in...

In the Panhandle Region, Clearwater Region and Salmon regions, the limit on bass is 6 (smallmouth and largemouth) but there is no length limit specified.

In The Southwest, Magic Valley, Upper Snake and Southeast regions, the limit is 6 bass (smallmouth and largemouth) and the length limit is none under 12".
