The HCC strain rainbows stocked in 1985 had totally <br />disappeared by September 1986, with an estimated survival of O.ll% one year <br />after stocking. This was the identical survival of the HCC strain in the <br />State Bridge (SB) section of the Rio Grande, while survival of ' the HCC <br />strain in the Coller Wildlife Area (CWA) section of the Rio Grande was only <br />0.017% (Nehring 1987). <br /> <br />In September 1986, this8-km section of the upper Gunnison was stocked <br />with lO,OOO, adipose-clipped Bellaire (BELL) strain rainbows which averaged <br />l2.4 cm (4.9 in.), at stocking. In,addition, l2,500 CRR strain rainbows <br />averaging 5 cm (2'in.) were also stocked the same day. Results of the 1987 <br />electroshocking of the upper Gunniaon River stations as well as comparative <br />data from 1985 through 1987 are given in Table 9.' <br /> <br />Table 9.
