 Non-Native Fish Strategic Plan

Background: Attachment G bullet number 5 to the document entitled “Invasive Fish Species Below 

Glen Canyon Dam: A Strategic Plan to Prevent, Detect and Respond” states that the Smallmouth 

Bass Ad Hoc Group (SBAHG) should convene on an annual basis prior to the Budget Ad Hoc Group

(BAHG) Triennial Work Plan (TWP) discussions to discuss the agenda topic shown above. Bullet 

number 5 further states that the SBAHG may also review and recommend updates to the plan, as 

necessary. This agenda item is meant to allow TWG members, sitting simultaneously as the SBAHG, 

to continue a discussion about this topic that began at the February Adaptive Management Work 

Group meeting and will occur at future BAHG meetings. Agencies who are involved in 

implementing invasive fish management actions will be requested to provide updates on those 

actions.
