Project: Invasive Species Management of Sacramento Pikeminnow to Support Steelhead Recovery

Description: Funding will be used to reduce predation on steelhead and increase abundance of steelhead in the Chorro Creek watershed by suppressing the invasive Sacramento pikeminnow population in Chorro Creek and Chorro Reservoir, San Luis Obispo County. Supression will have a direct benefit to steelhead by increasing juvenile survival and smolt production, which will lead to a long-term increase in the adult steelhead population. Additionally, pikeminnow control will improve the value and minimize risks of planned and ongoing habitat restoration and fish passage barrier projects which will provide habitat access.

Reference Number: 3600BQ2196016

Implemented By: Morro Bay National Estuary Program

Objective: Objectives for reducing pikeminnow in the Chorro Creek watershed will result in: 1) By Year 2024, the ratio of steelhead to pikeminnow (all ages) will be less than or equal to 1:1 in re-sampled habitat units. 2) By Year 2024 less than 20 sub-adult/adult pikeminnow that are greater than 200 mm standard length (SL) will be observed annually in snorkel surveys.
