The stocking of nonnative fishes into lakes of Lassen Volcanic National Park (LVNP) was discontinued in the late 1970s and many lakes have since returned to a fishless condition. Due to a lack of comprehensive surveys, however, present fish distributions were largely unknown as were impacts of fish predation on native biota. Here we present results of a study examining the distribution of introduced fishes and their ongoing effects on littoral macroinvertebrate and zooplankton assemblages among larger (>2 m deep), natural lakes and ponds likely to have been stocked in the past.

This "condition report" provides a summary of resources in the Thunder Bay National Marine Sanctuary (sanctuary)1, pressures on those resources, current conditions and trends, and management responses to the pressures that threaten the integrity of sanctuary resources. Specifically, the document includes information on the status and trends of water quality, habitat, living resources and maritime archaeological resources, and the human activities that affect them. It presents responses to a set of questions posed to all sanctuaries (Appendix A). Resource status of Thunder Bay is rated on a scale from good to poor, and the timelines used for comparison vary from topic to topic. Trends in the status of resources are also reported, and are generally based on observed changes in status over the past five years, unless otherwise specified.

This report documents the data and methods of estimation used in estimating the economic impact of commercial fishing catch from all four National Marine Sanctuaries in California on local county economies in terms of harvest revenue received by fishermen and the associated economic impacts, including multiplier impacts, on total output, value added, income and the number of full- and part-time jobs.
