Effects of burial on the heart cockle Clinocardium nuttallii and the Dungeness crab Cancer magister

Burial experiments with dredge spoil sand were performed in the laboratory using the heart cockle Clinocardium nuttalli and the Dungeness crab Cancer magister. All cockles buried by 5 cm or less re-established siphon contact with water in less than 24 h. Under 10 cm of sand, less than 50% reached the surface in 24 h while none did so under 20 cm of sand. All crabs reached the surface in less than 24 h after burial by 10 cm or less of sand, while none did so under 20 cm.

Purpose

The present laboratory study compared the effects of burial by different depths of dredged sand on two benthic animals, the relatively sedentary heart cockle Clinocardium nuttallii (Conrad) and the mobile Dungeness crab Cancer magister Dana. Such data may be useful as criteria when regulations concerning ocean disposal are formulated (IMCO etc., 1975).
