Improvement of methods for estimation of catchability for trawl survey systems with use of hydroacoustic means (on example of walleye pollock in the Okhotsk Sea)

In commercial fishery, catching properties of fishing gears are developed mostly for effective catch of fish, rather than for precise measurement of fish distribution density in water, so a problem of catchability exists and this parameter should be determined for each fishing gear. Various methods...
