Оценка коэффициента уловистости снюрревода датского типа с применением инструментальных методов

Based on the results of hydroacoustic surveys and data from personal experiments on the mechanics of Danish seine for the period from 2011 to estimate the catchability coefficient (CC). To measure the value of CC there were used three different approaches to calculation of the biomass in a suspective active zone of Danish seine. Analysis of the characteristics of each approach in combination with the data on the vertical distribution of fish received by hydroacoustic method allowed to determine the most likely horizon of the water column, the fish are herdered by the seine ropes to the catching zone when the ropes moving across the bottom.
