On June 11-12, 2013, Fish Biologist Anjanette Bowen of the Alpena Fish and Wildlife Conservation Office  assisted Cory Pusach and Ryan Katona from the La Crosse Fish Health Center with a fish health survey of Pendills Lake in Chippewa County, Michigan.

The lake serves as a back-up water supply for Pendills Creek National Fish Hatchery, which raises lake trout for stocking in the upper Great Lakes. Fish health sampling is important for keeping the hatchery disease and pathogen free. Samples were taken from Pendills Lake fish to determine if disease or pathogens are present in the fish community.

 

Fyke nets were used to sample fish from the lake. John Shuman from Pendills Creek NFH assisted with netting during part of the survey. Five species of fish were collected - brown bullhead, northern pike, pumpkinseed sunfish, rock bass, and yellow perch. The total catch was recorded and lengths were measured on a representative sample from each species.

Kidney and spleen samples were collected from a number of brown bullheads, pumpkinseed sunfish, rock bass, and yellow perch to detect bacterial and viral pathogens. The samples will be processed at the La Crosse Fish Health Center in Onalaska, Wisconsin and laboratory results on the pathology of the samples will be available at a later date.
