The discussion I had with the study's author helped me think through my strategy for fishing walleyes in deep water. Here's how I will go about it.
- target fish located in the "less deep" water (30 feet is better than 45 feet) fish progressively deeper only if necessary
- set the hook quickly to minimize removal time from deeply hooked fish
- get the fish back in the water fast (taking time for photos is likely to be harmful)
- anticipate some mortality and use these fish for eating in camp or for taking home
Fishing causes fish mortality, whether intentional or not. I hope you will consider what you can do to keep it to a minimum, no matter what species you fish.
