IDENTIFYING THE MOVEMENT RULES SEA LAMPREY USE TO NAVIGATE COMPLEX FLOWS

This two-year project will test a research framework for identifying the movement  rules sea lamprey use to navigate through heterogeneous flows and assess the  feasibility of applying this framework to sea lamprey control in the Great Lakes. The  framework has been used to improve downstream passage devices for salmonids in  the Columbia River. The project objectives are (1) To identify the movement rules sea  lamprey use to navigate through complex flows.  (2) To test how well the movement  rules recreate the movement tracks of real fish under the measurement conditions.   (3) To test the how well the movement rules predict real movement tracks for fish  under new hydrodynamic conditions.  In year 1, objectives 1 and 2 will be achieved by  (i) quantifying the movement tracks exhibited by individual sea lamprey, (ii)  quantifying and modeling of the hydrodynamic conditions experienced by the  swimming lamprey, (iii) integrating the movement track data with the hydrodynamic  model, and (iv) identifying and validating the stimulus-response (movement) rules  predicting the swimming paths. In year 2, objective 3 will be achieved by (v)  simulating movement paths expected for sea lamprey swimming in new  hydrodynamic conditions and (vi) experimentally assessing the accuracy of these  predictions.  The Great Lakes Fishery Commission views barriers and traps as viable  control alternatives to periodic, chemical treatment of streams and rivers with  lampricides and it has pledged to increase its reliance on these alternative forms of  control.  Our understanding of how sea lamprey respond to complex flows is lacking,  is recognized as an important research priority in the barrier and trapping theme  paper, and is an essential source of innovative ideas for the development of more  effective barrier, trap, and fishway designs.
