Criteria for coastwide crab condition sampling

Creator:: Snow, C. Dale, Stewart, Nelson E., Dahlstrom, Walter, Tegelberg, Herb, and Dungeness Crab Scientific Committee. Sub-Committee on Crab Condition Studies
Abstract:: “Prepared for the State/Federal Dungeness Crab Management Program.” Crabs molt every year. After they molt, their shells are soft and are not filled out with meat. It takes weeks for the crabs to fill out. The problem for fishery managers is that the timing of the crab molt varies from...

The identification of Dungeness crab from the power spectral density function of their acoustic signature

Creator:: Eghbali, Hassan J.
Abstract:: The power spectral density of the acoustic signature of Dungeness crab was calculated by the use of digital computer. The signal produced by the Dungeness crab was an analog signal. Therefore a conversion of the signal from analog to digital was necessary. This was done by sampling the acoustic signature...

Prediction of abundance of harvestable Dungeness crab (Cancer magister)

Creator:: Stefferud, Jerome Arthur
Abstract:: A method for predicting the harvest of commercial Dungeness crab (Cancer magister) one year in advance of the fishing season is described. The technique is based on the hypothesis that the relative abundance of sub-legal crabs one year is directly proportional to the harvest of legal crabs the following year....

Yaquina Bay South Jetty softshell crab problem

Creator:: Snow, C. Dale and Oregon. Fish Commission. Shellfish Investigations
Abstract:: In 1974, large numbers of Dungeness crabs migrated into tide pools near the South Jetty of Yaquina Bay and went through their annual molt. The public discovered the abundance of crabs, and found that they were easy prey during low tides. The situation prompted an emergency closure of the area...
