Delta Juvenile Fish Monitoring Program [DJFMP]
Description / purpose
The Delta Juvenile Fish Monitoring Program (DJFMP) has monitored natural-origin and hatchery-origin juvenile Chinook Salmon (Oncorhynchus tshawytscha) and other fish species within the San Francisco Estuary (SFE) since 1976 using a combination of midwater trawls and beach seines. Since 2000, three trawl sites and at least 58 beach seine sites have been sampled weekly or biweekly within the SFE and lower Sacramento and San Joaquin Rivers. The main objectives of the DJFMP are:
1. Document the long-term abundance and distribution of juvenile Chinook Salmon in the Delta.
2. Comprehensively monitor throughout the year to document the presence of all races of juvenile Chinook Salmon.
3. Intensively monitor juvenile Chinook salmon during the fall and winter months for use in managing water project operations (Delta Cross Channel gates and water export levels) on a real-time basis.
4. Document the abundance and distribution of Steelhead.
5. Document the abundance and distribution of non-salmonid species.
