The Kansas Department of Wildlife, Parks, and Tourism Fisheries Section utilizes low pulse direct current electrofishing to sample blue catfish populations for fisheries management purposes. When applying low pulse direct current, the fish exhibit galvanotaxis and are drawn to the surface. The temporarily stunned fish experience galvanonarcosis which causes the fish to lie motionless where they can be easily collected with long handled dip nets. Fish are counted, length and weight measurements are taken along with any other desirable data. Fish are then released unharmed back in to the lake. This video shows very good numbers of blue catfish on the surface after low pulse direct current electrofishing at El Dorado Reservoir.
