 Catching Fish by Suction

The vacuum cleaner principle applied to fishing on a wholesale scale

���A suction pipe is connected with a funnel-shaped net and a centrifugal pump, by means of which the fish are drawn up and deposited in a container on board the boat

��THE fish of the deep arc gelling wiser, if one can take the numerous devices in- vented for their capture as a criterion. Nets used by fishermen for centuries arc apparentK' being discarded in fa\or of more recent fisliing in\cnlions. ne of the most recent of these is an apparatus for cnlicing the fish into a net ant! then (hMwing them up through a pijie to a coiUaiiier on deck. C. P. L)roz, of .\ilvcrsun, Holland, is the inventor.

The apparatus comprises a suction pijie connected with a centrifugal ]iuinp, a source of light suih as an enclosed eleclric lamp placed in front of the suction o|)ening, and a funnel-shaped net so arranged as to guifli,' the fish to the suction opening. The

��fish, seeing the light, enter the net, ap- jiroach the suction opening and are drawn through the pipe and dcli\'crcd to a container on deck.

Steel hoops brace the net and strengthen it so that it retains its sha|)e in sjiiie of the action of the wa\'es.

The, net is secured at its rear end lo the suctioTi |ii|)e and at its front end to a frame pixotalK' susi:)endetl from the boat, so that the net can be removed from the pipe and raised together with the frame to the position shown by the dotted lines in the <lrawing.

There is a recess made in the boat into which the jiipi' nia\- be raised and stored awa\' when it is not in use.
