Perkinsville into a wide, alluvial valley (Camp Verde) before <br />entering a narrow, low gradient river valley ca. $0 km long, <br />downstream to Horseshoe Lake. Oak Creek, and to a lesser extent <br />West Clear and Wet Beaver creeks, are largely modified in lower <br />portions by diversions, gravel pits, and housing developments <br />which exceed natural riverine conditions. <br />Methods <br />Stocking of razorback sucker was by USl'WS and AGFD personnel <br />and equipment. The Salt and Gila rivers and tributaries were <br />stocked with fry and fingerling suckers reared at Dexter National <br />Fish Hatchery. Verde River stockings were of fingerlings reared <br />at Page Springs Hatchery (PSH) from Dexter produced fry. <br />Stocking strategies for fish size, number, location, method, and <br />time of year are discussed by Brooks et al. (In prep.). <br />Monitoring surveys were conducted in the Gila, Salt, and <br />Verde rivers and tributaries in proximity to razorback <br />introduction sites. Collections were by seines, hoop, gill and <br />trammel nets and electrofishers (backpack, raft, or boat). In <br />March 1985, netting and electrofishing surveys were conducted on <br />mainstem downstream reservoirs in attempts to collect pre- <br />spawning adults stocked as fry and fingerlings early in the <br />program (Brooks et al. In prep.). Near shore aggregation on <br />gravel/cobble bars, indicative of pre-spawn staging in Lake <br />Mohave razorback suckers (Minckley 1983), would presumably make <br />collections of adult razorback more likely. ~ <br />-3- <br />
