Evaluation of potential sources of sauger Sander canadensis for reintroduction into Lake Erie | Semantic Scholar

Comparison of seasonal migrations, habitat use, and diets of saugers and walleyes in the middle Missouri River of Montana suggests that the competition potential between these species is high.

Sauger reproduction and early life history have been studied to determine factors affecting year-class strength in Lewis and Clark Lake, a 28,000-acre reservoir on the South Dakota-Nebraska border, and adult year- class strength was inversely related to water level fluctuations over the spawning grounds.

A framework developed to assess the feasibility of one type of translocation—reintroduction was applied to the potential reintroduction of threatened bull trout Salvelinus confluentus into the Clackamas River, Oregon.

Lake sturgeon from 27 spawning locations were analyzed using 12 microsatellite loci and consistent genetic breaks were observed among three clusters of spawning populations: Hudson Bay–northern Lake Superior, (2) southernLake Superior, and (3) the rest of the Great Lakes.

Improved regulation of exploitation and present efforts by United States and Canadian government agencies to improve Great Lakes water quality, are expected to improve the success for long-term maintenance of percids in Lake Erie.

Results showed an increase in genetic diversity and a twofold decrease in the extent of genetic differentiation among stocked populations when compared to unstocked, and suggest that under certain scenarios, the genetic impacts of stocking could be of short duration.

Walleye (Stizostedion vitreum) from two northern Minnesota spawning stations simultaneously stocked as fry into five southern Minnesota lakes had different survival rates, and natural-origin walleye that descended from previous stockings significantly increased in percent of all sampled walleyes over the study.

Recovery of native sauger stocks will require a complete cessation of harvest, recovery of the natural hydrograph, recovered of sediment transport, recoveryof snags and organic matter dynamics, and re·connection of cut·off side channel morphology.
