FIELD: fish artificial breeding.
SUBSTANCE: invention relates to the artificial breeding of fish and can be used for the reproduction of stocks of brook trout. Spawning mounds are arranged by hand, three-layered at a distance from each other in spring streams. The first layer is made of river gravel, the second layer is made of light fascines, which form a nest for laying and incubating brook trout eggs. The third layer of the hillock is made of large river pebbles, while light fascines are made in the form of a bundle of ripe reeds with a diameter of 7-10 cm. Caviar is laid in the nest of each hillock using a transparent plastic 1.5-liter bottle with a cut-off bottom, finely perforated sides and a wide neck.
EFFECT: increased efficiency of artificially arranged brook trout spawning grounds.
