Synthesized Dataset of Length-Weight Regression Coefficients for Delta Fish

This dataset is a compilation of length-weight regression coefficients for fish species commonly found in the freshwater tidal habitats of the San Francisco Estuary. This effort was born out of the Delta Smelt Resiliency Strategy Aquatic Weed Control Action study, which, in order to calculate fish biomass, needed to calculate individual fish weights from their measured lengths. The Aquatic Weed Control study was supported by Interagency Ecological Program through the Endangered Species Act and is included in the Interagency Ecological Program 2017-2019 workplan. Weight is estimated from length using the exponential function W=a\ L^b. These can be calculated using the linear regression of the log-transformed equation (log⁡(W)=log⁡(a)+b log(L)). This dataset provides the species-specific a and b parameters. Associated publication(s) and relevant metadata information are included. Data was obtained either via database (fishbase.us) or peer-reviewed scientific papers. ## About This Federated Record This CNRA Open Data Platform record is based on metadata federated from the Environmental Data Initiative (EDI) Data Portal. Its purpose is to improve the discoverability of the data package through the CNRA Open Data Platform. The EDI Data Portal is the repository of record for this data package. Metadata, resource links, and supporting information displayed here may not reflect the latest updates available in EDI. Resources shown here—including Full Metadata, Provenance, and Data Quality Report—are provided to help users understand and evaluate the data package and the supporting information available from EDI. For the current data package, citation, DOI, data files, metadata, provenance, data quality documentation, revision history, and other supporting information, refer to the EDI data package landing page: https://portal.edirepository.org/nis/metadataviewer?packageid=edi.508.2&key=vqSpNwnbe91Bi8trB5RY25CoPD4 Access requirements, permissions, and authorization policies for resources hosted by EDI are established and managed independently of the CNRA Open Data Platform.
