if modified, might adversely affect use of confirmed spawning or nursery <br />areas; and <br />2. The genetic integrity of wild populations must be protected when using <br />hatchery-reared experimental animals. <br />There are obviously other stipulations that could be added, including a need <br />to develop adequate follow~up, and to provide for maintenance of any such <br />habitat developed. Also, protection of existing sensitive areas (USFWS 1987) <br />should be more fully discussed. As the program develops, hopefully these <br />issues will be more fully evaluated. <br />Stocking of Rare Fish Species <br />Stocking of Colorado squawfish for recovery has not been attempted for the <br />Green River basin because of the naturally reproducing population there. Some <br />stocking has occurred in 'nney Reservoir, an impoundment on the White River, <br />a tributary to the Green, but this was an experimental attempt to establish a <br />sport fishery. Colorado squawfish also have been stocked in other locations, <br />including the Upper Main Stem Colorado, and in sites located in the lower <br />Colorado River Basin. <br />Colorado squawfish were introduced in the Upper Main Stem Colorado River as <br />a population augmentation measure. This includes 1,474 6 year old Colorado <br />squawfish stocked in 1980 (Valdez et al 1982), ranging in size from 230-3709 <br />~,..~' <br />mm TL, and tagged with a Carlin dangler tag. A total of 17 of these fish have <br />29 <br />
