In 1993, sampling at Chandler Falls (RM 166.8) resulted in that year's <br />highest chub catch rate (0.092), which was only slightly greater than the most productive trend <br />site (Coal Creek = 0.075). <br />A total of nine Gila spp. were recaptured during these six trips. All were greater than 240mm <br />when first captured therefore growth was minimal (Chart and ILentsch 1997). All chubs were <br />recaptured at the their original capture location (Table 1). <br />DRAFT ~ 7 <br />,- <br />'~:4":i <br />
