Delta Juvenile Fish Monitoring Program
The goal of the DJFMP is to document the relative abundance, distribution, and survival of juvenile salmonids and other co-occurring fishes in the lower Sacramento and San Joaquin rivers, Delta and Bay for the protection, recovery and management of naturally produced salmonids and other native species in the Central Valley of California.
The Delta Juvenile Fish Monitoring Program (DJFMP) conducts annual monitoring of juvenile fishes, participates in multi-agency research activities, and contributes to several technical and management committees within the region.
All monitoring data are collected by Lodi Fish & Wildlife Office and are available on this web page or by contacting the data manager directly at (209) 334-2968 ext. 322 or via the following e-mail address: Jonathan_Speegle@fws.gov. Please contact us if you need documents in other formats.
Some of the more common data requests, as well as the Chipps Island survival calculations, have been compiled and are shown in the table below. Please note these data are preliminary and are subject to revision and correction.
