The Ecology of Chione Cancellata
Abstract:Chione cancellata occurs intertidally and sublittorally. It is mature at a length of about fifteen millimeters and an age of one year. There is little growth after four years. Chione spawns twice a year, in the winter and summer. Shell growth is positively correlated with temperature in immatures, but is depressed in summer in adults. The annual productivity is about 83 per cent of the standing crop, and half the productivity is in the form of spawn. A rich intertidal community produces a dry weight of tissue of 7.9 gm per square meter per year. An account of habitat and behavior is given.
