In all bodies of water, it is only a small portion of all habitat that supports nearly all of the fish that live there.

Some schools of thought even imply that nearly 90% of fish coexist in less than 10% of the entire surface area of ​​lakes and rivers. 

What to look for?

Several studies have shown that fish are naturally attracted to structures of all kinds. If a body of water were shaped like a bathtub, specimens of most species would wander just about anywhere. However, as soon as there is something that modifies the architectural composition, such as a point of rock or sand, the perimeter of an island, an underwater island, steep rocks, a pile of submerged rocks, etc. it attracts fish like magnets. They can hide there to hunt or not, camouflage themselves to feel safe, etc. Even the floral elaboration of the herbaria is an excellent hiding place. In fact, anything that breaks up the monotony of a flat bottom with no environmental frills will attract fish.

Things to Consider

As Antidote defines it so well, photosynthesis is “a synthesis of carbohydrates by plants and certain bacteria that use sunlight as an energy source”. It is also responsible for part of the formation of oxygen in water.

The air in our atmosphere contains 20 % oxygen or 200,000 ppm (parts per million ). In a body of water, under satisfactory conditions, there will be a dissolved oxygen concentration of more or less 10 ppm. When the days get shorter and there are fewer hours of sunshine, the natural production of dissolved oxygen decreases. 

I now let you imagine what happens after a few months of darkness under the ice. Plants gradually die and dissolved oxygen levels drop. In addition to being numbed by cold water, predators become even less vigorous when the ppm drops.


The great thing about nature is that not all plants die simultaneously. Some plant species survive much longer than others, while producing oxygen. 

When you drill a hole with your auger, if there are aquatic plants in decomposition, slightly odoriferous, which go up in the orifice, you will have well and truly understood that they no longer produce oxygen.

I have often suggested to you, in my writings, to target the flats with green grasses, still alive. You may now better understand why. One of the good ice fishing strategies is to position your tackle near a structure with living grass and try your luck all along its drop. You will thus be able to exploit the most comfortable and popular sites for the various species you are targeting.
