FOR EACH TYPE OF FISH you must prepare in a certain way. Each species behaves different - prefers varying depth, light and temperature. Fish isn't just fish. Got to have the right equipment to handle each type.
You have to study carefully the depth - if you miss the right depth you will end up hands empty. Each species prefer a certain depth. You'll need a sonar to measure that. A couple of meters from the the bottom, a little vegetation close to the shore-throw in a metalpiece-and-hook, no pike can resist that! Or try a living bait. Different story altogether. Link the line onto a pole at shore for the night, then get in early.
Speed is everything. Put your boat running a few knots per hour. Once you hit a colony, you just need some muscle to start pulling them up. Sounds easy? Chuck in many baits at the same time and it's a lollipop every time!
What about thickness of the line? If it's too thick, the metal bait will swim unevenly from one side to the other. A line too thin will break when the pike strikes, then you'll lose the effort.
Got to know your place. Got to read your echo-sounder. Got to know your fish. Got to know your bait. Got to know where to look, and how to look. And before anything else - you got to know what you're looking for.
