These silver salmon are believed to be the first three-year-old adults of this species to ascend the Sac- ramento to spawn. Biologists say there is no doubt they are the first mature fish to return from an experimental plant of 42,000 yearling silvers in Mill Creek in March 1956. Work- ers at the Fremont Weir hopefully dubbed them "Adam" and "Eve" before tagging them and permit- ting them to resume their upstream journey, states an August 16, 1957, pl:'ess release from California's Department of Fish and Game. The Sacramento River, an excellent king salmon stream, has never had a sil- ver salmon run. The experimental plant was made in the hope of establishing such a run. Silvers now enter coastal streams both north and south of the Golden Gate, but (except for one recorded stray in 1942) never entered the Sacramento until last fall. At that time, on the basis of counts at Fremont Weir and upstream recover- ies, fishery technicians estimated a run of 3,200 precocious salmon, all males, in the Sacramento River. Two small two-year-old females, returning from the March 1956 plant were artifically spawned, one at the Nimbus and the other at the Cole- man Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabil
