Data from “Larval and juvenile Longfin Smelt diets as a function of fish size and prey density in the San Francisco Estuary”
This publication includes the raw data from the manuscript: Lojkovic Burris, Z. P., R. D. Baxter, and C. E. Burdi. 2022. Larval and juvenile Longfin Smelt diets as a function of fish size and prey density in the San Francisco Estuary. California Fish and Wildlife Journal 108:e11. http://www.doi.org/10.51492/cfwj.108.11 Data includes the diets of larval and juvenile Longfin Smelt in the San Francisco Estuary from 2005 to 2008 in the form of diet by number, diet by weight, macroinvertebrate prey lengths, prey length-weight equations, and prey weight conversions. ## 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.

lfspreydefsandconversions Prey category definitions, taxonomic classifications, weight conversions and references. Wet weight values were used to calculate diet by weight values. For prey that did not have measured wet weight values from CDFW Diet Study fish, wet weight was calculated from published carbon weight values as Wet weight (ug)= ((carbon weight in ug C) / 0.42) / 0.13) where carbon weight is 42% of dry weight and dry weight is 13% of wet weight, which was adapted from Beers 1996. Beers, J.R. 1966. Studies on the chemical composition of the major zooplankton groups in the Sargasso Sea off Bermuda. Limnology and Oceanography 11:520-528. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
lfspreylengths Lengths of the larger prey (e.g. mysids, amphipods, fish, shrimp) found in stomachs. Note that some lengths were measured when prey were intact despite no corresponding length-weight equation (e.g. Cumaceans) to add to available knowledge of the species | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
lfspreylengthweighteqns Constant and exponent values needed to calculate length-weight relationship for large prey types (e.g. mysids and amphipods) used in the paper. Includes references where values came from and type of body length measurement that should be used to calculate length-weight relationship W = aL^b. W is the weight of the individual (g), L is the body length (mm), a is a constant, and b is an exponent. | CSV (EXTERNAL DOWNLOAD) | 09/25/26 | |
