In autumn 2002 the San Juan River Basin Recovery Implementation Program (SJRIP) began to implement an Augmentation Plan for Colorado pikeminnow (Ryden 2003). Based on research conducted in the mid-1990s, the Augmentation Plan called for stocking over 200,000 young-of-the-year (YOY) Colorado pikeminnow annually from 2002?2009. The objectives of the Augmentation Plan are to meet the Recovery Goals, which indicate the need for 800 adult Colorado pikeminnow throughout critical habitat in the San Juan River (USFWS 2002). In order to achieve an adult population of 800 fish, it has been hypothesized that Colorado pikeminnow must use the area of abundant native fish forage upstream from PNM Weir (Miller and Lamarra 2006). Therefore, the SJRIP [...]
