Abstract Details

2016, Master of Science, University of Toledo, Biology (Ecology).
Tributaries support diverse spawning habitats for three of the four major sub-stocks of Lake Erie walleye (Sander vitreus). Despite a long history of anthropogenic degradation and the extirpation of other potamodromous species, the Maumee River continues to support one of the largest fish migrations in the Laurentian Great Lakes. To determine if spawning habitat availability and quality could limit production of Maumee River walleye, the longitudinal distribution and relative abundance of walleye eggs deposited in a 34 km stretch of river were assessed. Eggs were collected using a diaphragm pump at ten sites in 2014 and eight sites in 2015 from mid-March to early May. In both years, a sharp decline in mean relative abundances from downstream spawning sites than upstream sites at river kilometer 30 suggest that spawning habitat connectivity in the Maumee River is lower than was previously known, and may be limiting production from the system.
