METHOD FOR FISHING WITH CONICAL DIPNET Russian patent published in 1995 - IPC

FIELD: commercial fishing. SUBSTANCE: method involves lowering conical dipnet with fish trap bridles and suction pipe of fish pump to the catching depth, attracting hydrobionts, and catching them by reciprocating the dipnet. Said dipnet is held for a certain time period on the lower horizon. The catch is emptied at a rotation speed of fish pump impeller which is 40-60% of nominal speed. The reduction of zone of action of hydrodynamic field is compensated for by catching the hydrobionts by dipnet chambers. EFFECT: higher efficiency. 1 dwg
