We use electrofishing boats to sample our bass populations around the state. Most of the sampling using occurs at night in the spring. However, there are a few lakes that are either sampled during the day in the spring (due to really turbid water) or are sampled at night in the fall. Electrofishing is conducted in streams at night in the tail waters for trout or during the day in the fall for sport fish sampling. We see all species of fish while we are out however we are normally just conducting annual bass sampling unless the trout program is sampling trout. I would have to disagree with causing the fish to turn off for two days. We see fish actively feeding while we are sampling and had people catch fish after we have been sampling in an area.
