Fishing from a kayak can be fun even for a casual angler. I was a fellow kayaker when a brown trout got caught by trolling on lake Haukivesi.
Trying to get the fish out of water is not the easiest part, especially if you have an average kayak, not one designed for fishing. The front hatch was used to transfer the fish to the shore because we were close to it.
When you are not angling but paddling, you should fasten your equipment well to your kayak. Under one strap on the deck is not enough while one is busy doing something else like trying to reach chanterelles from the shore without having to leave your boat.
Another angle to fishing is trying to catch fish with your camera. While I was close to the shore, I noticed this curious perch swimming under my kayak. I put my camera on a monopod and into the water and tried to catch him swimming. How elegant moves.
