The Delta Juvenile Fish Monitoring Program (DJFMP) was established in the 1970s to monitor juvenile salmon abundance in the San Francisco Bay-Delta using trawling and beach seine nets. Since then, the DJFMP has expanded its objective and sampling efforts. Today, the DJFMP continues to document the relative abundance, distribution and survival of juvenile salmonids and other fishes in the lower Sacramento and San Joaquin rivers, Delta and San Francisco Bay for the protection, recovery and management of naturally produced salmonids and other native species in the Central Valley of California. Learn more about the DJFMP at https://www.fws.gov/project/delta-juvenile-fish-monitoring-program DJFMP writes annual technical memoranda summarizing the data that we collect and providing initial analysis. DJFMP also publishes our data annually on EDI (https://portal.edirepository.org). The code housed in this repository is associated with the technical memoranda.
Funding for DJFMP has been provided by the US Bureau of Reclamation (agreement number R24PG00035) and the California Department of Water Resources (agreement number4600015072). This repository supports annual reporting and open science requirements associated with the US Bureau of Reclamation agreement.
Program R and various packages are required to run this code. R is a free, open-source program.
