A procedure for taking in of the catch from a trawl, where you, before the trawl is put into the water, fix a fishing pump (1) in the trawl sack and take the pumping pipe (2) as well as the power transmissions (3, 4, 5) some way up from the trawl, preferably up to the mouth of the trawl sack. When the catch has to be taken in, the trawl is hauled in, just as far that you can connect the pumping pipe and the power transmissions to the installations on board the ship. The taking in of the catch can then take place in just as bad weather as that which allows fishing, because connecting the transmissions takes little time, and after the connecting, it is of minor importance, if the net sinks. Furthermore the ship is fully manoeuvrable during the pumping. A trawl for use with the procedure is provided with a fishing pump, pumping pipe and power transmission. A pump for use with the procedure and for fitting in the trawl, comprises a fishing-pump of usual construction provided with protection buckles against blows and the like. The pump is also provided with buoyancy giving bodies to compensate for the weight. Furthermore the pump is provided with a throttle-valve to prevent packing of fish and dirt in the pump during fishing. |
