<br />. <br /> <br />GOALS AND OBJECTIVES <br /> <br />. <br /> <br />. <br /> <br />At the beginning of this study, in 2001, crews were asked to develop an effective <br /> <br />northern pike control program from Split Mountain in Dinosaur National Monument to Sand <br /> <br />Wash (the study area will be discussed in further detail in the next section), focusing their <br /> <br />removal efforts in areas of known northern pike concentrations. The goal of this control program <br /> <br />was to sufficiently reduce the abundance of adults such that predatory and competitive impacts <br /> <br />on growth, recruitment, and survival of endangered and other native fishes were minimized. <br /> <br />The study objectives were to: <br />1. Capture and remove (lethal) adult northern pike from reaches of the middle Green <br /> <br />River. <br /> <br />. <br /> <br />. <br /> <br />I <br /> <br />Reduce the abundance of adult northern pike in the middle Green River. After <br /> <br />2003, this objective was changed to "Maintain low occurrence of adult northern <br /> <br />pike in the middle Green River." <br /> <br />3. Determine the efficacy of removal efforts. <br /> <br />4. Identify the means and levels of northern pike control necessary to minimize the <br /> <br />threat of predation/competition on endangered and other native fishes. <br /> <br />The end product included herein is an evaluation of the effectiveness of this northern pike <br /> <br />removal program. <br /> <br />2. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />11 <br />
