Late-Holocene Dungeness crab (Cancer magister) harvest at an Oregon coast estuary
Coastal peoples worldwide harvested and consumed a wide variety of shellfish. Most archaeological analyses of shellfish remains tend to focus on bivalves such as clams and mussels while other shellfish such as gastropods, barnacles, and crabs have received much less attention. Here we examine the use of Dungeness crabs (Cancer magister) at a late-Holocene village on Netarts Bay, northern Oregon...
متن کاملEstablishing tolerable dungeness crab (Cancer magister) and razor clam (Siliqua patula) domoic acid contaminant levels.
Domoic acid has been found in razor clams (Siliqua patula) and dungeness crabs (Cancer magister) in Washington State and elsewhere on the West Coast of the United States. Due to toxic effects associated with domoic acid exposure, an effort has been made to establish tolerable domoic acid levels in crabs and clams obtained from commercial harvest and sale and from individual recreational harvest...
متن کاملRegeneration and molting effects on a proprioceptor organ in the Dungeness crab, Cancer magister.
Decapoda Crustacea molt in order to grow; some species, such as the Dungeness crab Cancer magister, achieve a very large size. Does sensory neuron hyperplasia in internal proprioceptors accompany this growth? To determine this, neurons in propodite-dactylopodite (PD) chordotonal organs were counted in first walking legs of juvenile (5th through 9th instar) and adult (10th through 13th instar) C...
متن کاملComparison of enzyme activities linked to acid–base regulation in a deep-sea and a sublittoral decapod crab species
When compared to the sublittoral Dungeness crab Cancer magister, the deep-sea Tanner crab Chionoecetes tanneri exhibited lower activities of enzymes involved in some of the processes essential for efficient acid–base regulation. Tissue enzymatic activities were compared between Dungeness crabs held in normoxia and Tanner crabs held in hypoxia—both treatments mimicking typical habitat oxygen lev...
متن کاملDynamic Mechanical Properties of Passive Single Cardiac Fibers from the Crab Cancer Magister
I determined the dynamic mechanical properties of single relaxed cardiac fibers from the Dungeness crab Cancer magister. Single fibers were mechanically isolated, chemically skinned and subjected to small-amplitude sinusoidal length perturbations over a wide range of strain rates and sarcomere lengths to characterize their viscoelastic behavior. The observed mechanical properties, together with...
