Date: Summer 2013
Experimental design:
Treatment (4 levels): oysters were reared in the lab in tanks which never contained crabs (0 hour), or contained crabs 2 hours, 24 hours, or 168 hours per week
Mesocosm (8 levels): the experiment included 32 tanks, 8 of which were assigned to each treatment
Replicate (3 levels): 3 oysters were sampled
