With nothing to do right now I was wondering what the affects of the deep snow and thick ice we have on our bites. As I started reading the mass amount of scientists different theories I kind of came to my own conclusions, the deeper the snow , the thicker the ice the slower the bite.Which is not really a big surprise to most of us who have ice fished for a while. I did find something interesting, pike have a higher tolerance as do perch, where as walleye, crappie ,blue gill and bass are more sensitive to low light conditions thus limiting their feeding and moving around so much. The way they explain it the brighter the sun the more active the fish will be, the predator fish will be more active in the evening after a long period of sun. The pan fish will be active during high sun periods. They say to ward off winter fish kill a pond or lake in the north should have depths of 25' to avoid a big kill, but the more plant life you have in the summer the better you are to a point, if the winter ice last until late march early April all that plant life starts to decay at a faster rate and burns up more oxygen. If you don't agree with me read up on it and come to your own conclusions .
