Multiple-pass, capture-recapture sampling was conducted in about 88% (819 river km) of warm water reaches of the Green River Basin, Utah and Colorado, to estimate demographic parameters for juvenile (< 400 mm TL), recruit (400 to 449 mm TL), and adult (> 450 mm TL) Colorado pikeminnow Ptychocheilus lucius. Three to six sampling passes were completed in each year for the Yampa River, middle Green River, White River, Desolation-Gray Canyon, and lower Green River reaches from 2006 to 2008. Parameter estimates derived from a Huggins robust-design multi-state model suggested about a 50% increase in abundance of adult Colorado pikeminnow throughout the Green River Basin over the study period, and about a 70% increase...

Capture?recapture sampling of 819 km of streams in the Green River subbasin, Utah and Colorado, of the Colorado River basin was conducted in 2000?2003 to estimate population demographic parameters and recovery status for endangered Colorado pikeminnow Ptychocheilus lucius. Parameter estimates from a Huggins robust-design, multistratum model suggested a basinwide decline in the abundance of adult (total length, ?450 mm) Colorado pikeminnow. Reductions were most severe in the middle Green River (59%) and White River (63%), the two largest population segments. Reductions were less severe in the Yampa River (29%), Desolation?Gray Canyon (11%), and lower Green River reaches (36%). In 2001, the first year the entire subbasin...
