C. River The catch per effort of channel catfish by electrofishing the White River by date and reach is shown in Table D-1. The highest catches occurred in the summer of 1994. During 1994 sample periods, river flow conditions were low and channel catfish were concentrated, channel catfish stunned by the electrical field were more visible to netters on the electrofishing boat than when flows were higher, and the channel catfish seemed to taxi fairly well to a low voltage field that could be used with the water conductivity. Unfortunately, the low flows made much of the river unnavigable so the sample reaches were fairly short. The second best catches occurred in the summer of 1993. Again flows were low. Also more channel catfish may inhabit the White River in Colorado during summer than eazlier in the yeaz. The average catch per effort of channel catfish for 1993 and -1994 from electrofishing the upper reach was 13 fish/hour and 3.5 fish/km, compared to 13 fish/hour and 3.9 fish/km for the lower reach (Table D-1). From this data it appears the channel catfish populations in both reaches are similar sized. Baited hoop nets had very low catch rates of 0.01-0.19 channel catfish per hour. Although different baits were used, none appeared to work better than others. One wild channel catfish was recaptured during river sampling downstream from Kenney Reservoir. This fish was originally captured July 1993 in a baited hoop net in the lower reach, and was recaptured the following day in another baited hoop net placed about 0.4 km downstream from the original capture site. The first hoop net was still fishing when the channel catfish was recaptured downstream. On the last day of-field work, September 3, 1993, 16 channel catfish were taken from a baited hoop net in the lower reach and transplanted to the upper end of Kenney Reservoir. These fish ranged in length between 311-551 mm TL and were mazked with individually numbered Floy tags. The purpose of this transplant was to increase the number of individually marked reservoir channel catfish for growth evaluation in the future. Only one of these fish was ever recaptured. It was caught by a fisherman the following spring (1994) about 1.6 km upstream from the reservoir in the White River. The angler did not report a length or weight from the fish so growth could not be determined. In 1995, one other channel catfish was taken from the White River above the reservoir. This was a stocked fish. It was collected by electrofishing the river about 11 km upstream from Kenney Reservoir. 12
