| Notes | In 1980, Oregon State University researchers developed an acoustic harassment device to deter harbor seals from feeding at hatcheries and gill nets. This device was used to keep harbor seals away from an experimental chum salmon hatchery at Whiskey Creek. It kept most, but not all seals away: by 1984, one to three seals would feed on the salmon, despite the deterrence. In 1985, researchers ran an experiment. They forced all the seals out of Netarts Bay and set up five devices at the entrance. Due to battery and electrical problems, several of the devices were not working through much of the experiment. The experiment ran for a week and about two-thirds of the seals stayed out of the bay while the partial deterrence was functioning. |
