Lake trout hatch rates using adults collected in 2019 from Northern Refuge, Lake Michigan

Data includes hatch, unfertilized, underdeveloped, and larval mortality count data of lake trout (Salvelinus namaycush) eggs fertilized from adult gametes collected within Northern Refuge reefs in Lake Michigan conducted by the U.S. Geological Survey Great Lakes Science Center during Fall 2019 gill net survey. Adult lake trout were collected using gill net (4.5, 5.5, and 6.0 inch) panels. Gametes were removed and fertilized in the field and then incubated at the Great Lakes Science Center Aquatic Research Laboratory in Ann Arbor, MI. Results are reported as date, collection reef, latitude, longitude, tray number, reef panel, and counts (unfertilized, dead or unsuccessful hatch, hatched, and larval mortality).
