Klamath Suckers

The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.

Factors limiting survival of juvenile endangered suckers.

Impaired water quality conditions in Upper Klamath Lake have been implicated in reduced survival of fishes and are a concern for recovery efforts.
