FIELD: commercial fishing; continuous method of fishing. ^ SUBSTANCE: proposed device has funnel with bell-like end with suction zone created by water flow and narrow end connected with fish intake hose. Device is furnished with load unit and lamps to create light field attracting fish to inlet hole of funnel. Funnel is made profiled in meridional section with inner streamlined surface, with inlet diameter at bell-like end providing position of suction zone border close to inlet hole. Lamps creating light field are displaced in direction of flow behind suction zone and they partly project into funnel space. Outer part of lamps is covered with cases non-transparent for light. ^ EFFECT: improved characteristics of hydrodynamic and light fields which increases efficiency of fishing. ^ 4 dwg |
