  • Patent number: 4142754
    Abstract: A series of bag shaped nets is hung in the fish locker of a ship or barge to receive fish caught in the ocean. Each net has four suspension loops on its upper end and hanger hooks are arranged in the locker to hold the top ends of the nets open in rectangular configuration in side by side relation with no gaps between adjacent nets so that all fish dropped into the locker will fall into the nets. At a shore station the filled nets are lifted out of the locker one at a time by a crane. One form of net has an open bottom end which is closed by a pucker rope. The contents of the net are discharged by releasing the pucker rope. In a modification, the net has a closed lower end connected to one end of a suspension rope. When a filled net is to be removed from the locker on a ship the other end of the suspension rope is connected to a crane hook and a bight in the rope is passed through the four suspension loops and supported on a releasable crane hook.
