Project Goal:

By comparing and contrasting hydrologic conditions and aquatic food web dynamics across the spectrum of existing wetland habitat types (i.e., river channel, managed wetlands, farm fields and bypasses), the project will: 1) improve understanding of aquatic food web productivity in the Sacramento Valley and 2) assess the potential for these diverse aquatic habitats, including the hundreds of thousands of acres of floodplain farmland and managed wetlands, to contribute food resources to the river ecosystem, bolster in-river and Delta food webs, and help support recovery of endangered fish populations.


5,000 acres of farmland under improved management to exporting fish food and an estimated 12,000 lbs of zooplankton fish food added to the Sacramento River.

Project Description

Re-integrating floodplain food resources to feed the river ecosystem. In 2017, CalTrout launched the Fish Food on Floodplain Farm Fields (Fish Food) project with goals to better understand aquatic food web productivity on managed floodplains, and to work with farmers and water suppliers to pioneer new practices aimed at reintegrating floodplain food sources back into the greater Sacramento Valley aquatic ecosystem in the hopes that it will recover fish and wildlife populations. In simple terms, we are putting the fish food made on the floodplain back into the river where it belongs and where it will help rebuild robust populations of native fish.

CalTrout's Fish Food on Floodplain Farm Fields is using innovative solutions to reintegrate food from the floodplain back to the river. The program works with farmers and water suppliers to pioneer new practices to help recover fish and wildlife populations in the greater Sacramento Valley.

In its second year, the FFFFF initiative conducted its first landscape-scale effort to reactivate floodplain food webs by flooding over 5,000 acres of rice fields in the Sacramento Valley. Capitalizing on our research showing that floodplains produce food resources 150 times greater than in the river, we worked with our partners to grow food on the flooded farm fields and transfer those resources back to the river where fish can access them.

This science-based approach to managing California's resources demonstrates that with innovative management practices, there is potential to boost the depleted food resources in Central Valley rivers and help recover endangered fish populations.
