• f ~ 1 • Paris River Fish Monitoring Annual Report flannelmouth sucker and speckled dace. 2 - Since a spawning bar has been identified close upstream from Site 1 (M. Brouder, Arizona Game and Fish Department, personal communication) an additional sampling site should be located at there and another between the spawning bar and the present Site 1. 3 -Past seine sampling has been habitat-selective in favor ofsmooth-bottomed runs, which may • have biased the catch. Therefore, additional samples should be taken from other areas. For example, rocky areas (e.g., riffles) may be sampled by using personnel to chase fish into a seine. 4 -Velocity was only measured on one trip in 1998 due to equipment not being available. Temperature, turbidity and velocity aze known to be the factors primarily influencing habitat selection by small fishes (Arizona Game and fish Deparimeni 1996a). Therefore, these factors should be measured consistently on each trip. 5 -Use of the Paris River by adult flannelmouth suckers and speckled dace appears to be influenced by Colorado River temperature. Colorado River turbidity and dischazge may also influence fish behavior. Therefore, these variables should be recorded from the Colorado River near the mouth of the Paris River on each sampling trip. 6 -Use night sampling with a winged hoop net to capture fishes, particularly adult flannelmouth • sucker, entering the mouth of the Paris after dark.
