Three multi-year data collection efforts were made: 1991?1994, 1998?2000, and 2003?2005. Primary objectives included capturing and marking Colorado pikeminnow > 250 mm long from throughout the study area, developing estimates of population abundance and survival rate and assessing trends in recruitment.
