FIELD: commercial fishery.
SUBSTANCE: method involves choosing space; setting fishing equipment; hauling-in fishing equipment and determining catching object, with vertical, bottom and vertical fishing longlines sequentially connected with one another being used as catching equipment; using buoy ropes of bottom longline as ridge for vertical longlines; attaching hooks along the entire length of bottom buoy ropes at 1.0-1.5 m pitch; determining catching objects by visible dimensional features; determining habitat horizon from formula: H=L·cos α, where H is habitat depth from water surface; L is distance from water surface to each of said hooks fixed on vertical longlines; α is angle defined between depth vertical in catching equipment setting region and buoy rope of vertical longline.
EFFECT: increased precision in determining distribution of fish fauna in bathyal zone, epi-, meso- and bathypelagial zone.
