One time, I went out in the White River with the Biologists @ Arkansas Game & Fish Dpet. It was at night like, 11:30 pm. They have big john boat with generator for the lights, and they have shocker wands that are in the water. Me and my buddy rode on the front deck (plywood spot to stand on) we had big nets. The Biologist would hit the shockers around the rocks and trees under water...these big ass German Brown Trout would slowly float to the top. They were still like 30 seconds. So while they are stunned we net them and the biologist grabs them, measures and trims a fin to mark the ones we have caught.
We hauled in over 1000 fish in like 4 hours. Of course they were released. the thing is, it was hard work, but very exciting. I saw trout from 2 lbs to 25 lbs that night. It was a very cool night. We were tired as hell. I mean scooping fish with a long handle net at that rate...it was a definate workout.
It was amazing. One night I definately needed a camera but did not have one.
