Spangler, G.R., and J.J. Collins, 1980. Response of Lake Whitefish (Coregonus clupeaformis) to the Control of Sea Lamprey (Petromyzon marinus) in Lake Huron, University of Minnesota Reprinted from Canadian Journal of Fisheries and Aquatic Sciences (1980) 37(11): 2039-2046 Response of Lake Whitefish (Coregonus clupeaformis) to the Control of Sea Lamprey (Petromyzon marinus) in Lake HuronChanges in population parameters of three stocks of whitefish (Coregonus clupeaformis) in Lake Huron following control of sea lamprey (Petromyzon marinus) have varied between the major basins of the lake. In the North Channel and main basin, whitefish survival rates in creased significantly, from values of 23 to 37% and 16 to 24%, respectively. In both areas the abundance of lamprey declined while whitefish increased. In Georgian Bay, whitefish populations did not reflect changes attributable to lamprey control, possibly because of low lamprey abundance. During the control period, whitefish survival rates declined from 57 to 39%, abundance declined and growth rates increased. Entire Paper |
