Description

Abstract: Crab fishing with a helicopter rather than a boat was introduced into Oregon early in 1977. The new innovation was met with suspicion and alarm by some. Some boat crabbers and observers claimed that the resource was being damaged because small crabs were being "rained" across the water and beach, that the wind blast from the rotor was harmful, and that crabs returned to the water in the pots were killed. Subsequent observations and experiments failed to verify these claims. It was also claimed that prolonged flight at high speeds would cause delayed mortalities in crabs that were returned to the water. A study was done November 3-December 1 to provide insight into that claim. The results of the study are covered in this report.
