The rice fields along the Yolo Causeway could help in rebuilding the state's dwindling salmon population.
Scientists at UC Davis say those fields, if flooded between harvests, can act as substitutes for natural spawning habitats -- which have been lost to development.
Thousands of Chinook Salmon were released into two fields in February and they had average growth rates that were the highest ever recorded in fresh water.
"We're providing a good habitat for both fish and birds on lands that really provide high-quality agriculture and some of the most important flood benefits in the state," Jacob Katz with UC Davis.
If there's an actual project the fields would be farmed in the summer and used as a temporary home for fish in the winter.
