Temperature effects on the early life history stages of the walleye (Stizostedion vitreum vitreum) and sauger (Stizostedion canadense) were examined. Walleye eggs and fry were exposed to six temperatures (6-21C) for effects on fertilization, incubation, and fry survival. Mature sauger were held and eggs were fertilized at four temperatures (9-18C). Both species were incubated at 6-21C. Sauger fry survival was also tested at 6-21C. Optimum fertilization temperatures were 6-12C for walleye and 9-15C for sauger. Optimum incubation temperatures were 12-15C for both walleye and sauger. A sharp drop or rise in temperature had no great effect on walleye fry and juvenile survival except when the upper lethal or lower lethal temperature was approached. Optimum temperature for juvenile walleye and sauger growth was 22C.
