PERFORMANCE OF FAST-START AND BURST SWIM BEHAVIOR OF SEA LAMPREY ANDNON-TARGET FISHES IN SHALLOW WATER

  The purpose of this study is to provide a proof-of-concept that wetted  ramps can serve as selective sea lamprey barriers. The hypotheses to  be tested are a) that fish with a fusiform body shape perform better  when partially submerged in terms of acceleration and maximum swim  velocity than adult sea lampreys and b) that a combination exists of  ramp angle, ramp length, water depth, and flow velocity that allows  non-target species to pass wetted ramps, but blocks adult sea lampreys.  OBJECTIVES:   1.    Compare fast-start swim performance (e.g. acceleration standardized  for mass, maximum velocity) of sea lampreys and other fish species  (test species: shiners, walleyes, suckers) in water depth ranging from  full to partial submersion (Phase I).  2.    Quantify the effect of gravity (ramp angle) and water velocity on  swim performance in the species mentioned above when burst swimming up  ramps of varying angles while partially submerged (Phase II).  Explore  which ramp combination blocks lamprey and allows passage of the other  species.  METHODS:   Migratory-stage sea lampreys and adults of three model, non-target  species (common shiner, white sucker, walleye) will be filmed with a  high-speed camera in the laboratory at Eastern Michigan University  while swimming in water of four depths (full submergence, submergence  to base of dorsal fin, 2.5 cm depth, submergence to lateral line). A  kinematic analysis will be done to compare various swim performance  parameters among species and water depth treatments. Objective I will  be tested in still water using fast-start responses, because  fast-starts are well researched and methodologically less challenging  than burst swimming in running water, yet should give a reliable basis  for cross-species swim performance comparisons. The results will be  used to test if the fusiform non-target fishes tested perform  relatively better than the anguilliform sea lampreys under conditions  of restricted water depth. Objective 2 will be tackled using a  laboratory flume with variable angles and water flows (depth and  velocity). Kinematic analysis of forced burst swimming and automated  video recordings of volitional swimming on the ramp will be carried  out to explore if a certain combination of flow and angle blocks sea  lampreys while allowing the other species to pass.
