Relationships Between Physiological Stress and Trace Toxic Substances in the Bay Mussel, Mytilus edulis, from San Francisco Bay, California
Martin M, Ichikawa G, Goetzl J, de los Reyes M, Stephenson MD. 1984. Relationships Between Physiological Stress and Trace Toxic Substances in the Bay Mussel, Mytilus edulis, from San Francisco Bay, California. Marine Environmental Research. 11(2):91-110
Resident populations of M. edulis from Tomales and San Francisco Bay, California, were measured for scope of growth, a physiological integration of the energy consumed by individual animals (feeding rate and assimilation efficiency) less the energy lost in metabolic processes (oxygen consumption and ammonia excretion). Scope for growth of mussels was significantly correlated with feeding rates. There was a significant decline in the scope for growth between the Golden Gate, at the bay's entrance and Redwood City in south San Francisco Bay. The scope for growth in resident M. edulis was significantly negatively correlated with increased environmental concentrations (from transplanted M. californianus body burden data) of the following trance elements and higher molecular weight chlorinated organic compounds: Cr, Cu, Hg and Ag, Al, Zn, total chlordanes, and dieldrin. Scope for growth was significantly correlated with body condition index (dry body weight/shell length).
