Which crab eats more oysters ?
European Green Crab?
Sylvia Yamada Zoology Department OSU
Crab Feeding Experiments – The European green crab is a devastating predator on
mussels, cockles, clams and oysters. But how does the per predation rate of this new invader compare with that of our native Dungeness crabs? Find out by helping Dr. Sylvia Yamada set up and monitor field experiments with commercial shellfish at Hatfield Marine Science Center. Shellfish growers need to know what to expect in the future when the green crab densities increase. You can sign up for 1- 4 internship (Z 410) or research credits (Z401) with Dr. Sylvia Yamada. (30 hours per term =1 credit.)

Sex Pheromones for Green Crab control –
The persistence of the non-native European green crab in Oregon and Washington estuaries stresses the need to develop effective control tools for this invader before their populations increase to impact native communities and shellfish beds. Sex pheromones hold great promise as such a tool. The female sex-pheromone is ready for field trials. Help Dr. Sylvia Yamada test the hypothesis that male green crabs are attracted more to pheromone-baited traps than to empty traps. Experiments will be conducted at Hatfield Marine Science Center and at Sally’s Bend in Yaquina Bay. You can sign up for 1- 4 internship (Z 410) or research credits (Z401) with Dr. Sylvia Yamada.
