The invention relates to methods for preventing kill of hydrobionts in the winter period at freezing of water reservoirs. The method involves arranging a net plastic cylinder in a water reservoir, the cylinder is filled with fibrous material of minimum thickness, in particular of 1-10 µm, and with a hydrophobic group on surface thereof, the cylinder is submerged for a depth larger than the maximum depth of freezing the water reservoir by 40- and raises for the same height above the ice level. |
