"usually" they wont travel to far from the spawning areas,...again "usually". Ive fished lakes that they went a lot farther than one would think, and others they were stacked up no more than 50 yards away. Depends on the body of water, location could depend on bottoms composition, available forage, available cover, TYPICAL wind direction,waters clarity, ph, available shade, etc. "I beleive" post spawn some fish will stack up on structure, some will roam, and some will stay shallow. Depending on the lake could be one of these, two, or all three.
I'm sure that if you research this you will find a plethera, of opinions. Most dependable way to determine this is studying the most previlent prey's habits and understanding other predatory species present to locate a area to start with, then scan the area with electronics. For example I will use a large lake in Maine,.... most abundant bait? smelts, other predators? Pike, Lake Trout. Salmon, The smelt at this time will be hovering over very deep water in a comfy temp range, they will be tight as the lakers and salmon will be attempting to corral them and pin them to structure adjacent to said deep water. The bass will locate on the structure waiting for the smelt to be pushed right to them. "some" of the larger smallies will actually join the lakers and salmon in this act and be right under the smelts waiting for the fluttering wounded smelts to fall right into their waiting jaws. And for where does this occur? usually on the northern shores deep drops, not too far from spawning areas, but most likely on a deeper flat "near" the deepest water.
As for techniques to learn, time with the right gear in hand.,... You may pick up a "new to you" technique and use it for a week and catch nothing, or you may learn it and in a snap be successful. Depends on your perception, fishes activity, and a bit of luck. Best way is to fish with someone that's knowledged in said technique. Experience is key, and willingness to share it is even better. A good angler will know most techniques, and be good at them. What they have to offer, and what you grasp from it, will determine your "schoolings grade". If you have no such luck to fish with someone, research.,..research,... and more research will be in your future. Eventually you will get it, but it may not be just that easy. Why you ask? ,...Another example.
I live in new england, and when i started bass fishing there wasnt any publications on bass fishing up here. all were about the awesome trout streams and fly fishing. I had bassmasters and fishing facts with bassmasters targeting the southern impoundments, and fishing facts focused mostly around the great lakes area, wisconsin etc. I had to take their tips and "try" them here. Some worked but most didnt. I tried for over 10 years to learn a baitcasting reel and a jig and pig, with absolutely no success whatsoever. disgusted i gave up,..... I joined a bass club and in a few months, nailed it. Being tutored on something is a much more beneficial venture.
