FIELD: fishing and fish breeding.
SUBSTANCE: invention relates to lake fishing and can be used in the cultivation of fish in the fish-kill and periodically fish-kill lakes. Device for aeration of water includes a fish-kill lake or a reservoir. Self-regulating mechanism contains the vertical link (1) of the pipe, in which the air diffuser (3) is located. Horizontal link (4) of the pipe is provided with the float (5), in its upper part the float is shaped as a hemisphere. One end of the horizontal link (4) of the pipe is provided with the nozzle (6), which is shaped like a ball, the shape of which is made using the confuser, with the outlet nozzle (7). Other end of the horizontal link (4) of the pipe is connected using the flexible bellows to the vertical link (1) of the pipe, in which the air diffuser (3) is located. Air diffuser (3) is connected using the hose (8) to the compressor. Horizontal link (4) of the pipe is also provided with the freight anchor (11) with the tension cable (12).
EFFECT: increased efficiency of aeration during operation in different temperature conditions.
