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.
