    Endangered Species

    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

    Mountain Lakes Guide: Absaroka, Beartooth & Crazies

    2021 MOUNTAIN LAKES GUIDE Silver Lake ABSAROKA - BEARTOOTH & CRAZY MOUNTAINS Fellow Angler: This booklet is intended to pass on information collected over many years about the fishery of the Absaroka-Beartooth high country lakes. Since Pat Marcuson began surveying these lakes in 1967, many individuals have hefted a heavy pack and worked the high country for Fish, Wildlife and Parks. They have brought back the raw data and personal observations necessary to formulate management schemes for the 300+ lakes in this area containing fish. While the information presented here is not intended as a guide for hiking/camping or fishing techniques, it should help wilderness users to better plan their trips according to individual preferences and abilities. Fish species present in the Absaroka-Beartooth lakes include Yellowstone cutthroat trout, brook trout, rainbow trout, golden trout, arctic grayling, and variations of cutthroat/rainbow/golden trout hybrids. These lake fisheries generally fall into two categories: self-sustaining and stocked. Self-sustaining lakes have enough spawning habitat to allow fish to restock themselves year after year. These often contain so many fish that while fishing can be fast, the average fish size will be small. The average size and number of fish present change very little from year to year in most of these lakes. Lakes without spawning potential must be planted regularly to sustain a fishery. Standard stocking in the Beartooths is 50-100 Yellowstone cutthroat trout fingerlings per acre every eight years. Special situations may call for different species, numbers, or frequency of plants. For instance, lakes with heavy fishing pressure tend to be stocked more often and at higher densities.

    Frequently Asked Questions Proposed Rule to Remove Borax Lake Chub from the Federal List of Threatened and Endangered Species

    Frequently Asked Questions Proposed Rule to Remove Borax Lake Chub from the Federal List of Threatened and Endangered Species What action is being taken by the U.S. Fish and Wildlife Service? The Service is proposing to remove Borax Lake chub (Siphateles boraxobius) from the list of threatened and endangered species (delist) under the Endangered Species Act. What type of fish are these? The Borax Lake chub is a small minnow in the Family Cyprinidae, found only in Borax Lake of Harney County, Oregon. It is an opportunistic omnivore, eating both plants and animals. The diets of juveniles and adults are similar and include aquatic and terrestrial insects, algae, mollusks and mollusk eggs, aquatic worms, fish scales, spiders, and seeds. Males, and some females, reach reproductive maturity within one year. Spawning primarily occurs in the spring but can occur year-around. The reproductive behavior and length of incubation is unknown. Where is this fish found? The only place in the world where Borax Lake chub lives is Borax Lake. Borax Lake lies in the Alvord Basin, part of the larger Great Basin, which was dominated by a much larger Alvord Lake approximately 10,000 years ago. As Alvord Lake receded, native fishes became restricted to remaining springs, lakes, and creeks. Individuals from Alvord Lake’s ancestral chub became isolated in the geothermal springs of Borax Lake and over time the isolation and unique environmental conditions resulted in adaptations that differentiated the fish into the species now recognized as Borax Lake chub. Borax Lake is a 10.2 acre geothermally heated alkaline spring-fed lake in southeastern Oregon.
