I actually just got back from a trip to northern wiscosin for a yearly ritual of crappies and smallies. The key to crappie at least on this large 800+ acre lake that I fish is to be mobile and mobile in technique also. During our 6 days of fishing we caught crappie anywhere from 3-20 ft. of water. Crappies are mobile fish by nature especially at this point of the year and all. Right now most fish will be coming off the spawn. However just a week or two back one could find fish in all different stages of the spawn, pre, post and transition all on one same body of water. Even once crappies spawn they dont go into any one set pattern for the remainder of the open water fishing season. Many people believe this. I once did myself. Once I began "searching" for crappies my success has increased UNBELIEVABLY. I too once assumed that just because it was July and 95 degress and a water temp of 79 degrees that crappies would be suspended over deeper water flats. While this will be the case on many a day I cant tell you how many times after not having luck over the deeper flat instead of assuming that they "just weren't biting that day", moving into the shallows wether mud flats or structure areas has proven to be really successful. Time of day also plays out to be an unpredictable factor and not always in the ways the pro's profess. For example last week while fishing I locted crappie on a shallow underwater structure one morning in 6 ft. of water. Fishing was tremendous and a limit for the day was taken in short time. The very next morning I returned to this spot and found only two crappie for the taking. What changed, nothing. Water temp, weather condition, phase of the spawn all consitent from the day before. Rather than assuming that they just weren't biting. I decided to move off the shallows, past the breakline and check a deeper water hole in 20 ft. of water. Now remember its 8 a.m. Most crappie literature would suggest that early mornings the fish would be shallow and near structure. After anchoring up on this deeper water hole I began to catch fish, one after another as fast as I could. What happened, You tell me???? The point is dont get locked into any one mind set. I think that this is the biggest mistake most fishermen make. Its what I call the "they just weren't biting" excuse. However what they are forgetting is that "they just werent biting where you were at the time". I do not profess to be an expert by any means, I can only offer that mobility and searching for fish has proven to be succesful for me. As far as techiques. Crappies will be taken on any thing from live bait minnows, waxies and crawlers to jigs of varying weight worked at varying speed. The one method that I like is the slip bobber. Slip bobber rigging keeps you mobile and allows you to work deeper or shallow water without much time changing your rigging.
Good fishing, tight lines and take a kid fishing when ever you have a chance. It will be one of the greatest experiences of your life!!!!
