1 1 1 1 year; Table 10). Stocking activity from available vendor records was included in the stocking information provided above if a spatial location for individual stocking events could be determined. In general, importation records have not been intended to track locations where fish stocking occurs. The records often indicated "statewide" in the "destination" column. Given the large number of nonnative species with unknown destinations, we thought it important to outline the variety of species being imported into Colorado (Table 12). The most frequently imported species were consistent with stocking activity known to occur in western Colorado. Black crappie, bluegill, channel catfish, fathead minnow, largemouth bass, and grass carp each composed 8-12% of the importation events, accounting for the majority of fish species imported. Hybrid striped bass, smallmouth bass, walleye and yellow perch were the next most frequently imported species at 4.5 to 6% of all impartation events. All other species composed fewer than 2% of total imports. Private lake licenses for the years 1997-2001 were most frequently issued for stocking triploid grass carp, bass species and fathead minnow (Figures 14a-f). Commercial lake licenses were rare (Figure 15), consisting only of 3 locations from 1997-2001. The limitations of the lake license database for our purposes were that we had little information on existing licenses (issued earlier than 1997) or what stocking activity occurred in these waters. It is possible that we in fact were in possession of records of stocking activity under these licenses, but there was no consistent code or other information linking the databases in such a way as to track actual stocking activity. Further, private lake licenses are issued as lifetime licenses, allowing functionally a one time reporting of stocking activity when the licenses are obtained. Commercial lake licenses require annual renewal. No detailed information was available for denied permits. Lori Martin (CDOW, Grand Junction) indicated that denials were rare, and she was unsure whether or not any detailed, denied permit records were commonly retained by the CDOW. In the private fish stocking permit database we had in which permitted stocking is described, there were six permits listed as denied for the year 2000 in western Colorado (Table 13). The reasons given for denial included screening requirements and fish species that were not permissible for the stocking site indicated on the permit. The CDOW's nonnative, nonsahnonid fish stocking records for public ponds and reservoirs in western Colorado from 1997-2001 is provided in Table 11. The CDOW stocked bluegill, channel catfish, black crappie, triploid grass carp, and largemouth bass below the 6,500- feet elevation contour. Additionally, bluegill and largemouth bass were stocked in the 100-year floodplain and only bluegills were stocked within the 50-year floodplain. The CDOW only stocked waters with permissible species that were adequately isolated from riverine critical habitat areas in accordance with the Stocking Procedures (CDOW et al. 1996). 15
