Bioelectric responses from the isolated eye of the purple shore
crab were measured by the electroretinogram with stimulation by
light from wavelengths of 250 to 800 nm, strontium-yttrium-90 beta
radiation, 17.5 keV x-radiation, and 3-cm microwaves.
Peak sensitivities to light stimulation were found at 350 and 500
nm. These peaks...
The Hemigrapsus oregonensis population at Coquille Point in
the Yaquina Bay Estuary on the Central Oregon Coast was studied
from April, 1972 through May, 1973. The population was found to be
vertically stratified from the 1 ft level to the 5 ft level. Population
densities were found to be most...
Means of improving yield and quality of cooked meat from Dungeness crab (Cancer magister) were investigated. Processing factors of cooking time, cooking medium, and condensed phosphate treatment were evaluated. The effect of condensed phosphate treatment and its interrelationship with cooking time and medium on meat was determined.
Meat yield (wet...
"Recent concerns have been raised by commercial crab interests relating to the size and character of the recreational fishery for dungeness crab in ocean waters off Oregon. In response to those concerns, in May of 1999 the Oregon Department of Fish and Wildlife's Ocean Sampling Project began counting the number...
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...
