Data Management


All monitoring data are collected by STFWO and are available on this web page or by contacting the data manager directly at (209) 946-6400 ext. 322 or via the following e-mail address: Jonathan_Speegle@fws.gov. Please contact us if you need any documents in another format.

Some of the more common data requests have been compiled and placed in the table below, as well as the Chipps Island survival calculations. Please note these data are preliminary and are subject to revision and correction.

Catch per unit effort (CPUE) has been calculated for all seines and trawls after 1985; however, prior to 1985, sample dimensions and volumes were not recorded. Volume for trawls were calculated as (flow meter * net face area * flow meter correction value). Volume for seines were calculated as (net length * net width * net depth)/ 2. CPUE was calculated as (catch/volume).

Face Area of Chipps Island mid-water trawl net = 18.58 m2, Mossdale and Sacramento Kodiak trawl nets = 12.54 m2, Sacramento mid-water trawl net = 5.08 m2. The correction value of the flow meters = 0.026873.

The results of our studies have been shared in various arenas: workshops, IEP newsletter articles, gray literature in the form of annual reports, testimony to the state water resources control board and peer-reviewed journal and symposium articles.
