Scope and content
Fish inventory studies were conducted by Walter Momot, Sam Stephenson, and the students of biology class 4221, to examine trends in abundance and population variables for key indicator fish species. Sam Stephenson was a University of Manitoba Ph.D. student working with Momot as a teaching assistant. Connie Hartviksen, LU biology research and teaching assistant, performed taxonomic verifications and notations.
Connie Hartviksen noted on February 14, 1992, the status of their inventory since 1988 had collected specimens from 120 creeks and rivers, approximately 155 lakes in Northwestern Ontario.
The LU data collection including biology 4221 class represents 150 streams, 4x 150 for river data and 640 lakes concentrated in the Great Lakes-St Lawrence Primary watershed division, 2nd and 5th secondary watershed divisions in Ontario, within those two divisions 10 tertiary watershed divisions 2AD (units; 22, 19,1,4,5,6,24,23,7,10,9,11,13), 2AE (2), 4GA(16), 5QA(units; 8,4), 5PB(units; 1, 25,5,24,22,23) 5PA(3,5,7,8), 2AA(units; 1,2,3,4), 4GB(units 5,4,3,11), 2AB (all units,5 Lake Superior tributaries, 2AC (all units except 4 and 5, 21 Lake Superior tributaries)
This collection includes correspondence between Dr. Crossman and Dr. Momot regarding the verification of rare fish species. These fish have either been introduced or adapting to an environmental stressor such as climate change. Positive identification is an important step to mapping and documenting changes to their distribution overtime.
