 They do it to study fish oftentimes. So they'll do it in rivers, streams, ponds, lakes. They do that to check fish, check the health of the fish, tag fish. All of that goes into when they stun a fish to relocate them. When they stun them, I have so many questions. This is so fascinating to me. When they stun them, do they just float to the top? Just hanging out? They get stunned and they stop swimming and they just float?
