SUPPLEMENTARY INFORMATION:

ESA-Listed Species Covered in This Notice

This notice is relevant to the following ESA-listed species: endangered Sacramento River winter-run Chinook salmon ( Oncorhynchus tshawytscha) evolutionarily significant unit (ESU), threatened Central Valley spring-run Chinook salmon ( O. tshawytscha) ESU, threatened California Central Valley steelhead ( O. mykiss) Distinct Population Segment (DPS), and threatened southern DPS of North American green sturgeon ( Acipenser medirostris).

Permit 18181-4R

Notice was published in the Federal Register (86 FR 44696) on August 13, 2021, that a permit application had been submitted by CDFW to enhance the propagation and survival of species listed under the ESA. Under Permit 18181-4R, CDFW proposes to carry out rescues, research, and monitoring activities in California's Central Valley. Monitoring will provide information on the timing, composition, and relative abundance of Central Valley Chinook salmon and steelhead populations. Data collected over several years is expected to improve the overall understanding of the status of the species and aid in the recovery and protection of the anadromous fish populations in the Sacramento River Basin.

Permit 21477-2R

Notice was published in the Federal Register (87 FR 52751) on August 29, 2022, that a permit application had been submitted by FISHBIO to enhance the propagation and survival of species listed under the ESA. Under Permit 21477-2R, FISHBIO will continue to implement a nonnative predator research and pilot fish removal program in the Stanislaus River. The program aims to investigate whether removal is an effective strategy to improve overall conditions for native fish, specifically the survival of juvenile salmonids.

In compliance with the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.), a final determination has been made that the activities proposed are categorically excluded from the requirement to prepare an environmental assessment or environmental impact statement.

Authority

Scientific research permits are issued in accordance with section 10(a)(1)(A) of the ESA (16 U.S.C. 1531 et. seq) and regulations governing listed fish and wildlife permits (50 CFR 222-226). NMFS issues permits based on finding that such permits: (1) are applied for in good faith; (2) if granted and exercised, would not operate to the disadvantage of the listed species that are the subject of the permit; and (3) are consistent with the purposes and policy of section 2 of the ESA. The authority to take listed species is subject to conditions set forth in the permits.
