MULTIPLE CONGENITAL SPLENIC CYSTS IN WILD TROUT

Two wild brown trout (Salmo trutta) removed from a small pool in the River Clyde, Scotland, had gross abnormalities of the splenic tissue. Histopathology showed that they both possessed multiple splenic cysts, which in view of the close similarities in the scale readings of the two fish, and the rarity of the condition, suggested that both were from the same spawning, and that the cysts were congenital.
