Regeneration and molting effects on a proprioceptor organ in the Dungeness crab, Cancer magister.

Evaluating the population genetic structure of Dungeness crab (Cancer magister) off the Oregon coast

Establishing 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...

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...

Does feeding limit cardiovascular modulation in the Dungeness crab Cancer magister during hypoxia?

Decapod crustaceans inhabit aquatic environments that are frequently subjected to changes in oxygen content. The physiological mechanisms that allow them to cope with periodic episodes of hypoxia have been well documented. Most crustaceans exhibit a bradycardia coupled with diversion of haemolymph from digestive organs towards ventral structures. However, all these experiments were conducted on...

Comparison 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...
