We report the occurrence of white sturgeon Acipenser transmontanus eggs in guts of four species of fish from the Columbia River. Three of the species—northern squawfish Ptychocheilus oregonensis , largescale sucker Catostomus macrocheilus , and prickly sentpin Cottus asper —are native to the river and one, common carp Cvprinus carpio , is exotic.
