Includes bibliographical references. "Mortality of Lake Ontario lake trout eggs appears to have a higher sensitivity to physical shock than other stocks in laboratory tests. How these differences relate to survival in the wild is unclear. Bottom currents are one factor that may induce shock causing egg mortality. These were monitored at a lake trout spawning reef off Stoney Creek in Lake Ontario from September to December, 1999 to determine the duration and magnitude of high currents that could lead to physical shock"--Abstract.
