Abstract
  • Private hatchery operations continued in 1973 and 1974 on more of an ex­perimental than production basis. For 1973-brood chums, OSU increased their production at Whiskey Creek to a release of 761,000 fry and the state sold 247,500 eggs to private operators. AduIt returns to Whiskey Creek in 1973 were encouraging but did not provide clear evidence that chum hatcheries are successful. The larger return of chum in 1974 provided more conclusive evidence that the hatchery significantly contributed to adult runs. The good return of adult chum to Whiskey Creek in 1974 resulted in the sale of 1.0 million eggs each to Keta Corporation and Siuslaw Fisheries. Chum eggs were imported by the Fish Commission from Washington for experi­mentation and release at three cooperating private chum hatcheries south of Cascade Head. In 1973, most of the fish provided to one hatchery died due to interruption of their water supply. Some fry were fed at the other hatchery. Results where variable, but the experiments provided useful information and experience.
