Cedar River Fish Diets 20002001

Cedar River Fish Diets 20002001

InPort Dataset ID: 17857

InPort Entity ID: 36829

Counts of diet items identified in fish stomach samples using a compound microscope. Diet includes invertebrates (larvae or nymph; pupae; adult) and fish from the stream, and adjacent terrestrial invertebrates that fall into stream. Objective of collecting these data were to establish baseline data on resident fish diets before provision of fish passage at the dam in 2003. Fish passage was installed to allow Pacific salmon access to the watershed above the dam for the first time in 100 yrs. For details on sample collection and processing see Kiffney, P. M., C. J. Volk, and J. Hall. 2002. Community and ecosystem attributes of the Cedar River and tributaries before arrival of anadromous salmonids. Technical report submitted to Seattle Public Utilities.

Columns

NameSocrata field nameColumn name in sgr mountData typeDescription
Speciesscientific_namescientific_nameTextScientific name of collected fish. Fish caught by angling or electrofishing. Cottidae comprised mostly of torrent (Cottus rhotheus) sculpin with ~ 3 % riffle sculpin (C. gulosa). Rainbow trout = Oncorhynchus mykiss; cutthroat trout = O. clarkii clarkii. Trout fry were too small to be defined as cutthroat or rainbow.
