CONSTRUCTION OF ALLOPELAGIC TRAWL BOARD OF IMPROVED EFFICIENCY, OBTAINED USING MATERIALS AND METHODS OF UNIVERSAL ACCESSIBILITY Russian patent published in 2013 - IPC A01K73/45 

FIELD: agriculture.

SUBSTANCE: trawl board has front and rear edges, at least one main deflector housing and at least one slat. At least a part of the trawl board has a profile in which at least one slat has a front edge located in front of the rear edge of at least one main deflector housing. In the first version, at least one slat is located at an internal angle formed by converging of the first imaginary straight line connecting the shortest distance between the front and the rear edges, at least one slat and the second imaginary straight line connecting the front and the rear edges selected from the group consisting of front and rear edges, at least one main deflector housing, and the front and the rear edges of the trawl board. In the second version, each of at least two slats is located at an internal angle formed by converging of the first imaginary straight line connecting the shortest distance between the front and the rear edges of each of at least two slats, and the second imaginary straight line connecting the front and the rear edges selected from the group consisting of the edges of one main deflector housing and the edge of the trawl board.

EFFECT: method enables to increase the efficiency of trawling.
