The main objectives of our effects-driven assessment of cumulative effects were to document the baseline conditions of fish performance, the yearly variability in fish performance, and the trends in fish responses to existing or potential stres-rors over time, in order to make some assessment of the existing "accumulated environmental state" in the Moose River system. Our effects-driven approach uses an iterative assessment to define the integrated response of organisms to existing The Moose River study design involved three main components:

1) The geographic distribution of tributaries allowed an examination of longitudinal variability between sites on adjacent tributaries, upstream of major developments.

2) The existence of an undeveloped system on the Missinaibi River allowed an examination of latitudinal variability within a site as distance downstream progressed.

3) The multi-year nature of the study allowed an examination of both seasonal and annual variability in fish responses.
