DEVICE PREVENTING FISH FROM LEAVING TRAWL |
摘要 |
FIELD: agricultural industry; physics. ^ SUBSTANCE: device used for preventing fish from leaving the trawl consists of equal groups of acoustic-and-optic emitters of sound and light pulse signals, and echo-sounding fish control sensors in the trawl cross sections, which are discretely located along the trawl envelope from its mouth to the trawl bag. Echo-sounding sensors are installed after the appropriate acoustic-pulse emitters relative to trawl mouth, and acoustic-optic emitters are made so that they can form acoustic and optic areas directed at an angle to longitudinal trawl axis in the direction of trawl bag. ^ EFFECT: improving fish trawling productivity. ^ 1 dwg |
