Description :
The structure of fish stocks in the pelagic areas of Paanajärvi, a deep northern lake in a natural state, was characterized by means of echo surveys and test fishing in 1992-1994. The pelagic fish densities were in general relatively large, their size distribution resembling more that of pelagic areas in practically unfished natural lakes than that of exploited lakes. The structure of the pelagic fish assemblage in Paanajärvi stresses the importance of nature conservation as means of evaluating gradual changes in the environment caused by human activities.
