What effect will this late ice-over have on the Walleye fishing when we are able to get out? Will the higher oxegen levels change the fishing patterns? Will the fish be more aggressive? Will they go deeper or stay in the shallows? Will the Perch still school late February?
fish patterns... depend on a lot of different things. Most zoo plankton are attracted to phytoplankton. so with higher levels of oxygen taking place were these two micro organisms live you will find more fish. school fish or otherwise. With the lake getting as much sunlight as it is the zoo plankton and phytoplankton will be closer to the surface so that the proper amount of sunlight can be gatherd to produce photosynthesis. If the proper amout of photosynthesis is taking place the fish will be anywhere. i believe that as most days progress the phytoplankton will gradually rise depending upon the amount of sunlight. producing fish both on the bottom and just of in the morning right at dusk and the night (dawn). during the day these micro-organisms will become suspended.
I would start by setting up deep and then move into shallower water depending upon the structure your fishing. (rocks, gravel, mud, sand)
Yep...............like IxR IcE Man said, fish patterns depend on ALOT of different things. This year we may be experiencing the beginning of the impact of the invasion of the Zebra mussels to boot.
Zebra mussels being the incredible ‘bio-filters' that they are, are so efficient at competing for food, that they are cleaning up too much of the available food needed, such as plankton, small zooplankton, and algae - needed to sustain other life forms in a water body. This food, consumed by the mussels, then isn't available to feed other plants/critters which in turn, in the eco/web of life, feed other and larger plants/critters, and eventually starvation, or severe population reductions of the larger animals - SUCH AS WALLEYE, NORTHERN, MUSKIE,PERCH, SMALLMOUTH, TULLIBE and EELPOUT happens. In fact, walleye puppies, and other small fish fry and minnows eat plankton, zooplankton and insects, and small food particles that the mussels compete with them for. Larger walleye, of course, eat primarily minnows as fodder, and a few insect critters. It should be abundantly clear that if there is no food available for these minute critters, then there will be less of them, and consequently, much less food for walleye in the overall eco/food chain web.
Also, some of these smaller fish/.insects actually use water structure, and its constituents, as cover, such as turbidity, or simply put, unclear/stained or murky water. Much of this ‘stained' water is from the plankton, zooplankton and algae in the water. Once this is gone, then a host of fish can be successful at gobblin' these smaller forage fish, and eliminate the numbers available for themselves and others.
In addition to these actual eco-foodstuffs, zebra mussels also compete for some of the fish's needed elements, such as, and in some water, very importantly, calcium, and others (elements) that may not be in over/adequate abundance.
But, I think the walleye and perch will be biting better because of the clear water.
Hell, they might even be able to see the gill nets and not swim into them!!
I just hope the tribes don't get the word on "The Secret Weapon", is all. We'll be DONE!
