Improving The Effectiveness Of Portable Sea Lamprey Traps

The purpose of this two year project is to develop modifications to   portable traps that will   improve their effectiveness at trapping sea lampreys.  At the outset   we will make detailed   observations of the behavior of spawning-phase sea lampreys in   relation to the portable trap   design that is currently in wide use in the Great Lakes basin;   rectangular in shape with wire   mesh walls, entrance funnels at both ends and "fingers" at the trap   entrances designed to   allow inward passage only.  We will make the behavioral observations   in a sea lamprey   spawning stream with a portable trap located parallel to the   downstream face of a sea   lamprey barrier, the most common site for deployment.  From these   observations we will   develop modifications to the trap for testing in an indoor flume   facility at the University of   Guelph which simulates the conditions found at a sea lamprey barrier   (year 1), followed by   more extensive testing in a sea lamprey stream (Year 2).  Our first   priority will be to develop   modifications that increase trap effectiveness and are practical for   retrofitting to existing   traps.  Our second priority will be to investigate the roles of trap   lighting and "attractant"   water flow in improving trap effectiveness.
