PLANT FOR TREPANGS CULTIVATION Russian patent published in 2020 - IPC A01K61/00 

FIELD: fishing and fish farming.

SUBSTANCE: plant includes 1 to N bottom open-type cages 1 arranged at bottom of fish-breeding section in parallel rows and kept from surfacing and movement by bottom anchors 3 by means of external tension brace cables 2. Each cage 1 includes rectangular base and vertical walls from the net cloth. Vertical walls and the base of the cage are interconnected by cross-linking at the points of their crossing along the line of abutment. Base of each cage is additionally equipped with cables of internal diagonal, longitudinal and transverse braces. Upper edge of the vertical walls of the cage is connected to a rope having positive buoyancy. Pelagic part is made of ropes and floats, placed above the cage and connected to the latter by means of ropes. At that, pelagic part of installation is made in the form of collectors from propylene rope with threads of the same rope entwined in it along entire length with weaved ends to monothread. Each collector with its lower end is attached to the rope of the upper edge of the vertical walls of the cage at the intersection of its walls, and the top ends of the collectors are attached to the floats, which hold the collectors and walls of the cage inside the water column in the vertical position, without detaching the base of the cage from the ground.

EFFECT: invention ensures growing of trepangs on low-productive fish-breeding areas.
