Fish hole / Oxygen-Supplying Bucket

Fish hole
Fish hole

When the winter comes and the lake ices over, fishes would die from oxygen deficiency, especially in high-altitude areas. Many fishermen will regularly chisel holes on the ice to save the fishes.
This oxygen-adding bucket can be placed in the lake before the icing up. This double-layered column floats with attached weight at bottom.
The ice reaching 10cm thick allows people to walk upon. Under this circumstance, the inner bucket filled with ice can be twisted out, thus letting in oxygen to the water. Meanwhile, the hole facilitates fish feeding and even fishing.
