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 tliese is an apparatus for 

 cnlicing the fish into a net ant! tlien (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 

 whicli the jiipi' nia\- be raised and stored 

 awa\' when it is not in use.
