Cell-free filtrates from tumors
collected from adult walleyes during the spring spawning run
were used in the initial attempt at experimental transmission
of walleye dermal sarcoma to young-of-the-year (age 0+) walleyes.
The fish were maintained in the laboratory in water at 10C. Fish
received an intramusacular injection of cell-free tumor filtrate
into he hypaxial muscle. Tumors were not observed grossly, but
were observed in fish following histological evaluation of skin
biopsies.
