Abstract
    Mussels were transplanted to four sites along a pollution gradient in Narragansett Bay. After one month, mussels were sampled from each station and their physiological responses (oxygen consumption, feeding rate, absorption efficiency and ammonia excretion) were measured under controlled laboratory conditions. The physiological stress indices, scope for growth, oxygen to nitrogen ratio and growth efficiency were calculated. There was a significant decline in the performance and physiological condition of mussels from south to north along Narragansett Bay, and this was associated with increasing pollution.
