Swept volume trawl efficiency for two different trawls were determined to
be 28 and 60%, respectively by comparing the volume densities of capelin
determined by echointegrator, with catch size and swept volume of the trawl.
Escape of capelin through different parts of the trawl was examined by
attatching small meshed bags at different positions of the trawl.
