It's the risks and reaping the rewards concept. To catch a fish or increase your chances of catching the fish, you have to target structures and covers. So it goes that you will snag here and there and risk losing your lure, or catching the fish that will snag you into structure.
Last week, night fishing I was using a slip bobber set up and set it up close just behind some rocks in the current break. Sure enough had a bite and it immediately snagged. Problem was the fish snagged the sinker portion just perfect. Well I pulled and the line had to give and there goes my expensive nite lite bobber. I watch it just float down the river in the cover of darkness and the red light eventually drfted around the river bend and out of sight.
Now a week later, I went fishing again and caught a walleye off of some sucker cutbait for catfishing. It wasn't until much later after the sunrose high and bright, did I notice there was a long snell sticking out from it's mouth with an attached swivel that vaguely looked familiar to the one from my slip bobber set up the week before. I looked down it's mouth and clearly saw a gut hook. I used the pliers and got the hook out and sure enough the hook looks just like the hooks I use. Looking at this set up, it just dawned upon me, it was from the my slip bobber set up that snagged the week before.
Lure recovery in some fashion is always a bonus. In this cast just some terminal tackle.
