    Center Comments to the California Department of Fish and Game

    July 24, 2006 Ryan Broderick, Director California Department of Fish and Game 1416 Ninth Street, 12th Floor Sacramento, CA 95814 RE: Improving efficiency of California’s fish hatchery system Dear Director Broderick: On behalf of the Pacific Rivers Council and Center for Biological Diversity, we are writing to express our concerns about the state’s fish hatchery and stocking system and to recommend needed changes that will ensure that the system does not negatively impact California’s native biological diversity. This letter is an update to our letter of August 31, 2005. With this letter, we are enclosing many of the scientific studies we relied on in developing this letter. Fish hatcheries and the stocking of fish into lakes and streams cause numerous measurable, significant environmental effects on California ecosystems. Based on these impacts, numerous policy changes are needed to ensure that the Department of Fish and Game’s (“DFG”) operation of the state’s hatchery and stocking program do not adversely affect California’s environment. Further, as currently operated, the state’s hatchery and stocking program do not comply with the California Environmental Quality Act, Administrative Procedures Act, California Endangered Species Act, and federal Endangered Species Act. The impacts to California’s environment, and needed policy changes to bring the state’s hatchery and stocking program into compliance with applicable state and federal laws, are described below. I. FISH STOCKING NEGATIVELY IMPACTS CALIFORNIA’S NATIVE SALMONIDS, INCLUDING THREATENED AND ENDANGERED SPECIES Introduced salmonids negatively impact native salmonids in a variety of ways. Moyle, et. al. (1996) notes that “Introduction of non-native fish species has also been the single biggest factor associated with fish declines in the Sierra Nevada.” Moyle also notes that introduced species are contributing to the decline of 18 species of native Sierra Nevada fish species, and are a major factor in the decline of eight of those species.

The preferred option will maintain the current boardwalk configuration in the basin, and make improvements to the trail from the main park road. The geothermal basin and the trail to it are closed this year, for work on the trail. According park spokeswoman Karen Haner, the necessary approvals for the work are expected in May, but due to snow at the park work won’t start then. The first step will be replacing the boardwalks with new structures designed to handle winter snow loads and the acidic conditions in the basin. They would be modular and could be moved as necessitated by the changes of the thermal features. The preferred alternative calls for enlarging the viewing platforms in the basin at both the Big Boiler and Pyrite Pool.
