<br />Table 5. <br /> <br />Colorado River relative catch rates for monitoring conducted within six months of stocking events. Effort for each <br />method is defined as EL (electrofishing) = hours shocked, SN (seining) = number of habitats seined, HP/FN (hoop & <br />tyke nets) = net sets of approximately 24 hours, and TR (trammel nets) = number of net sets (approximately 6 hrs each). <br /> <br /> St~cki~g...~.........Stocking Number AvgTL <br /> Stucked.........
