Many <br />hatchery-raised stocked fish will not survive in the wild, underscoring the need to continue <br />making habitat improvements - such as building fish passageways, improving stream flows, and <br />restOling wetland habitat - initiated by the Recovery Program. Biologists believe these habitat <br />improvements are essential to the success of stocking effOlts and to recovery of endangered <br />Colorado River basin fish. <br /> <br />6 <br />
