METHOD OF FISHING AND CATCHING MARINE INVERTEBRATES

摘要

FIELD: agriculture.;SUBSTANCE: invention may be used in the fishery of aquatic organisms positively reacting to light. Method of catching fish and marine invertebrates is to place on the perimetre of the boat of light sources parallel to the water surface for at least two levels with the possibility of rotation about the vertical and/or one of the horizontal axis and/or towards their longitudinal axis, at that the power of light sources placed on the lower level is lower than the power of light sources located on the upper level. Concentration of catch is carried out by displacement of commercial peak of the spectral characteristic of light sources located on the lower level, towards the red light and/or their alternate turning-off towards the light sources located above the gear. Preferably, the light sources of the upper level with a capacity of up to 5 kW are placed above the deck at the height of the upper tier of ship masts. At the lower level the lamps are used with capacity from 0.5 to 1.5 kW. Upon completion of the concentration with the well-known techniques the object of fishing is captured, the gear is raised, and the catch is notched.;EFFECT: provision of opportunities for regulation of the light field in a wide range at all stages of fishing, from attraction the object of fishing to its seizure by fishing gear, which contributes to the efficiency of fishing.;4 cl, 11 dwg
