MongilloMongillo Washington Department of FISH AND WILDLIFE Fish Management Program Freshwater Resource Division Washington State Status Report for the Pygmy Whitefish by Molly Hallock and Paul E. Mongillo Washington Department of Fish and Wildlife Fish Management Program 600 Capitol Way North Olympia, Washington 98501-1091 September 1998 The Washington Department of Fish and Wildlife maintains a list of endangered, threatened and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011, Appendix A). In 1990, the Washington Fish and Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297, Appendix B). The procedures include how species listing will be initiated, criteria for listing and de-listing, public review and recovery and management of listed species. The first step in the process is to develop a preliminary species status report. The report includes a review of information relevant to the species’ status in Washington and addresses factors affecting its status including, but not limited to: historic, current, and future species population trends, natural history including ecological relationships, historic and current habitat trends, population demographics and their relationship to long term sustainability, and historic and current species management activities. The procedures then provide for a 90-day public review opportunity for interested parties to submit new scientific data relevant to the status report, classification recommendation, and any State Environmental Policy Act findings. During the 90-day review period, the Department holds statewide public meetings to answer questions and take comments.

David | Nicholls State University, Department of Biological Sciences, Thibodaux, LA While sometimes difficult to admit, perspectives of European and white males have overwhelmingly dominated fisheries science and management in the USA. This dynamic is exemplified by bias against “rough fish”— a pejorative ascribing low- to- zero value for countless native fishes. One product of this bias is that biologists have ironically worked against conservation of diverse fishes for over a century, and these problems persist today.

  • Acipenser Brevirostrum
    AR-405 BIOLOGICAL ASSESSMENT OF SHORTNOSE STURGEON Acipenser brevirostrum Prepared by the Shortnose Sturgeon Status Review Team for the National Marine Fisheries Service National Oceanic and Atmospheric Administration November 1, 2010 Acknowledgements i The biological review of shortnose sturgeon was conducted by a team of scientists from state and Federal natural resource agencies that manage and conduct research on shortnose sturgeon along their range of the United States east coast. This review was dependent on the expertise of this status review team and from information obtained from scientific literature and data provided by various other state and Federal agencies and individuals. In addition to the biologists who contributed to this report (noted below), the Shortnose Stugeon Status Review Team would like to acknowledge the contributions of Mary Colligan, Julie Crocker, Michael Dadswell, Kim Damon-Randall, Michael Erwin, Amanda Frick, Jeff Guyon, Robert Hoffman, Kristen Koyama, Christine Lipsky, Sarah Laporte, Sean McDermott, Steve Mierzykowski, Wesley Patrick, Pat Scida, Tim Sheehan, and Mary Tshikaya. The Status Review Team would also like to thank the peer reviewers, Dr. Mark Bain, Dr. Matthew Litvak, Dr. David Secor, and Dr. John Waldman for their helpful comments and suggestions. Finally, the SRT is indebted to Jessica Pruden who greatly assisted the team in finding the energy to finalize the review – her continued support and encouragement was invaluable. Due to some of the similarities between shortnose and Atlantic sturgeon life history strategies, this document includes text that was taken directly from the 2007 Atlantic Sturgeon Status Review Report (ASSRT 2007), with consent from the authors, to expedite the writing process.

MAKE THE CALL: 1-800-TIP-MONT FISH IDENTIFICATION KEY If you don’t know, let it go! CUTTHROAT TROUT are frequently mistaken for Rainbow Trout (see pictures below): 1. Turn the fish over and look under the jaw. Does it have a red or orange stripe? If yes—the fish is a Cutthroat Trout. Carefully release all Cutthroat Trout that cannot be legally harvested (see page 10, releasing fish). BULL TROUT are frequently mistaken for Brook Trout, Lake Trout or Brown Trout (see below): 1. Look for white edges on the front of the lower fins. If yes—it may be a Bull Trout. 2. Check the shape of the tail. Bull Trout have only a slightly forked tail compared to the lake trout’s deeply forked tail. 3. Is the dorsal (top) fin a clear olive color with no black spots or dark wavy lines? If yes—the fish is a Bull Trout. Carefully release Bull Trout (see page 10, releasing fish). MONTANA LAW REQUIRES: n All Bull Trout must be released immediately in Montana unless authorized. See Western District regulations. n Cutthroat Trout must be released immediately in many Montana waters. Check the district standard regulations and exceptions to know where you can harvest Cutthroat Trout.

    AN ABSTRACT OT' THE THESIS OT' Paul Edward Reimers for the M. S. in Fisheries (Narne) (5@ ( Major) Date thesis is presented Title DISTRIBUTION OF FISHES IN TRIBUTARIES OT' THE LOWER COLUMBIA RIVER Redacted for Privacy Abstract approved profes sor) During 1963 and 1964 collections were made in tributaries of the lower Colurnbia River and literature was reviewed to cornpile a list of fishes frorn that area. Based on available sources and collections in this study, a total of. 28 farnilies and 77 species are known from the lower Colurnbia River. Most of the fishes are rnarine or have rnarine affinities. Freshwater fishes include eight farnilies and ?9 species, but only three farnilies and eight species are prirnary. In the Colurnbia River the peripheral farnily Cottidae reaches great developrnent in the absence of a rrrore extensive prirnary fauna. Seven of the 12 species of Cottus known frorn the basin occur in the lower tributaries and were found to be the rnost widespread species there. LocaI distribution of 25 selected species is discussed, and used to gain an understanding of the relationship of the fauna of the Co1urn- bia River with the fauna of the Puget Sound drainage and coastal strearns of Oregon and Washington. These 25 selected species in- cluded I7 species which are recorded frorn the lower Columbia Riv- €r, and eight other species which are possibly present there. A nurnber of species occur throughout the Colurnbia River basin and rnay have interchanged with other drainages at several points. The absence of several species frorn the Rrget Sound drainage was associated with their absence frorn tributaries of the lower Colurnbia River.
