METHODOLOGY <br />,.-' <br />• t`~ <br />Adult . I• , ~ <br />~G~ r~ <br />The results incorporate pertinent data from the ISMP with specific study efforts. Sampling for <br />adult fish was completed using two techniques, electrofishing and trammel netting. Electrofishing <br />was conducted along the shorelines and in any flooded habitat available (most commonly tributary <br />or wash mouths). The electrofishing ~ boat was a 16' aluminum jon boat. The eiectrofishing <br />field was created with a pulsed DC current (typically 300 V; 5-7 amps; 20-40 mgHtz) generated <br />with an onboard AC generator converted through a Coffelt VVP-15. Electrofishing was <br />conducted in three reaches: `~ke~eAe~s from Swasey rapid (RM 131.8) to the town of <br />Green River, Ut.

Light trap <br />entry slit sizes varied from 2mm to 6mm, however most traps were 4mm. Light traps were usually <br />set in the late afternoon or early evening, and traps were picked up as close to sunrise as possible. <br />DRAFT 6 <br />
