Green River relative catch rates for monitoring conducted within six months of stocking events. Effort for each method
is defined as EL (electro fishing) = hours shocked, SN (seining) = number of habitats seined, HPIFN (hoop & fyke nets)
= net nights of approximately 24 hours and TR (trammel nets) = number of net sets (approximately 6 hrs each).

1 Origin of catches after the spring of 1999 monitoring represent estimations based on stocked size classes, the actual cohort of origin could not
be determined for fish stocked after the spring of 1999 monitoring. The use of coded wire tags and non-lethal sampling only reveal that
recaptured fish are hatchery-reared.
2 CPUE = Catch per unit effort
3 Relative catch rate (RCR) is calculated as ((CPUE)/#Stocked)* I 000
