A study was conducted to determine if walleye dermal sarcoma could be experimentally transmitted by waterborne exposure of tumor‐free walleyes Stizostedion vitreum to tumor‐positive walleyes by cohabitation. Uninfected walleyes were placed in a common raceway with tumor‐positive fish for either 5 or 15 d. Direct contact between the two groups of fish was prevented by two screen barriers. The exposed fish were then maintained in the laboratory for a total of 20 weeks. Walleye dermal sarcoma developed in 89% and 71% of the fish exposed for 5 and 15 d, respectively. There was no significant difference ( P > 0.05) in incidence of tumors between the two groups of fish exposed for different lengths of time.
