FIELD: applicable in increase of natural food production in fish breeding, breeding of muskrats and waterfowls, and also for combining the functions of separate reservoirs in fish breeding. SUBSTANCE: multiple extension of bank line ensures stable supply of natural food for fishes from bank, and considerably increases the food base of muskrats and waterfowls, and improves conditions of their nesting. Construction of T-shaped mounds over the periphery of bank line above the water level and forming many sections of microreservoirs interconnected by channels with the main reservoir, increases not only extension of bank line but allows also combination of functions of various reservoirs in fish breeding. EFFECT: higher efficiency. |
