Detritus-Based Food Webs: Exploitation by Juvenile Chum Salmon (Oncorhynchus keta).
Harpacticoid copepods are the principal food of chum salmon during the first critical weeks of estuarine life. Heterotrophic food sources are preferentially ingested by harpacticoids. A commercially valuable fisheries resource, usually considered to be planktivorous, is related to a detritus-based, benthically derived food web.
