Organisms living in marine waters are numerous and varied. Examiningtheir biological signaIs could he/p to evaluate and protect their health and that of their environment. This publication focuses on this topic, answering the fo/lowing questions: What are the measurable biological signaIs in marine organisms? Do they reflect the state of health of individuals, populations or ecosystems? Can they provide information about the specificity and level of chemical pollution? Are measurement results From bioassays useful in predicting and limiting ecological dysfunctions? ln conclusion, an integrated, operational approach is proposed to carry out environmental assessments which take biological and spatiotemporal diversity in marine waters into account.
