Fish Guidance and Exclusion Barrier

Abstract

One embodiment of a fish guidance and exclusion barrier having an upper reticulated section ( 10 ) imbricated by a lower reticulated section ( 12 ) which communicates with the upper section. The upper and lower sections are attached in an above water position to a floating device ( 24 ) with the lower section being suspended from the floating device utilizing funicular leads ( 22 ). The funicular leads are affixed to the floating device with latch type connectors ( 20 ) attached to loop type mounts ( 18 ) and to the lower sections with latch type connectors attached through grommets ( 16 ). Other embodiments are described and shown.

1 . A fish guidance and exclusion barrier device means to divert or prevent the downstream progression of fish and or debris within a body of water comprising: A plurality of suspended reticulated means to allow the flow of water beyond said means and prevent the passage of fish or debris beyond said means. Said screen or reticulated means as described above may extend below the surface of the water for a predetermined length. 
     
     
         2 . The barrier of  claim 1  wherein said reticulated means consists of upper and lower sections. 
     
     
         3 . The barrier of  claim 1  wherein a plurality of barriers may be suspended longitudinally across a pre-determined span. 
     
     
         4 . The barrier of  claim 3  wherein a plurality of longitudinally suspended barriers may be affixed end to end means to provide a continuous barrier for a predetermined length. 
     
     
         5 . The barrier of  claim 1  wherein said upper and lower sections may be attached to a floating device 
     
     
         6 . The barrier of  claim 5  wherein the attachment means of said upper and lower sections is positioned in an above water location.
