Using of fish optomotor reaction for fisheries efficiency increasing
Possibilities of fish behavior reactions use for increasing of traditional fishing gears efficiency and for creation of new methods of fishery are discussed, in particular optomotor reactions, as the most significant for fish life. Thereupon the data on background illumination by the Sun, the Moon, and starry sky are presented for different depths and times of night, by author's measurements and cited data, as well as the original data on intensity of bioluminescence provoked by moving net cloth. Imperative visual orientation of pelagic fish toward moving fishing gears at any time of day and night is concluded. New promising devices and means of fish catching with using of optomotor reactions are offered.
