Description:Growth of the green sea urchin, Strongylocentrotus droebachiensis, has become an area of increased interest in the Gulf of Maine with the explosion of the sea urchin fishery. Growth studies in this student project included a comparison of varying diets of herbivory, omnivory and carnivory; a comparison of low and high wave exposure habitats; and a mark recapture field study. Results support the conclusions of previous researches diet of the kelp Laminaria saccharina with the encrusting bryozoan, Membranipora membranacea, stimulates optimal growth. Growth in lab-fed urchins was superior to growth in natural habitats; study of habitat effects suggests a preference for high wave action.
