<br />------------------- <br /> <br />SAN JUAN RIVER <br />COLORADO PIKEMINNOW POPULATION ESTIMATE <br />· PROBLEMS AND THINGS TO REMEMBER! <br /> <br />· The study from which this data came was never intended to be <br />performed as a population estimate study <br />- It was a fish community characterization study <br />- The lack of repeated, riverwide sampling in all years (1991-1995) <br />makes extrapolating this estimate to the river as a whole impossible! <br />· The dearth of adult wild fish collections from 1996-2001 has <br />precluded a more up-to-date population estimate from being <br />performed <br />- Only 3 wild pikeminnow have been collected since October 1995 <br />- 2 juveniles (363 & 432 mm TL) near Lake Powell in 1996 <br />- 1 adult, originally captured in April 1993, recaptured in 1998, 1999, <br />and 2000 (all from RM 136.6 - 119.2) <br />
