Abstract
Способ определения коэффициента уловистости трала, включающий нахождение частного от деления количества рыб, пойманных тралом, на их количество перед тралом, определяемое с помощью эхолота, на траловой доске, отличающийся тем, что размещают дополнительное гидроакустическое эхолоционное устройство на траловых ваерах, обеспечивающее гидроакустическое лоцирование объектов промысла перед тралом, а гидроакустическое лоцирование с траловой доски - определение положения границ зоны, в пределах которой выполняется оценка количества рыбы перед тралом. A method for determining the trawl catch coefficient, including finding the quotient of dividing the number of fish caught by the trawl by their number in front of the trawl, determined using an echo sounder, on a trawl board, characterized in that an additional sonar device is placed on the trawl warmers, providing hydroacoustic location of fishing objects in front of the trawl, and sonar locating from the trawl board — determining the position of the boundaries of the zone within which the number of fish Ed trawl.
