Spawning Distribution and Habitat Use of Adult Pacific and Western Brook Lampreys in Smith River, Oregon American Fisheries Society Symposium 72:173–189, 2009 © 2009 by the American Fisheries Society Spawning Distribution and Habitat Use of Adult Pacific and Western Brook Lampreys in Smith River, Oregon STEPHANIE L. GUNCKE L *, KIM K. JONE S , AND STEVEN E. JACOB S Oregon Department of Fish and Wildlife, 28655 Highway 34, Corvallis, Oregon 97333, USA Abstract.—Pacific lampreys Entosphenus tridentatus (formerly Lampetra triden- tata) and western brook lampreys L. richardsoni are observed in many coastal Oregon basins; however, few data are available to adequately describe their distribution and spawning habitat associations. To document landscape-scale distribution and habitat use of spawning adult lampreys, we conducted biweekly redd surveys at 62 random- ly selected sites in Smith River (Umpqua basin, Oregon). Characteristics of lamprey habitat were measured at the redd, habitat unit, and reach scales to quantify available and occupied habitat. Pacific lampreys were found primarily in wider, low-elevation streams, whereas western brook lampreys were more widespread but concentrated in headwater and low-order streams. At the unit scale, unit type and dominant substrate were weakly correlated to presence of spawning lampreys. Both species spawned in gravel rich habitats, predominantly pool tail-outs and low gradient riffles. This study infers habitat associations and broad-scale distribution within a coastal basin to assist in the design of monitoring strategies and population assessments at a regional scale.

  • Relationships Between Anadromous Lampreys and Their Host
    RELATIONSHIPS BETWEEN ANADROMOUS LAMPREYS AND THEIR HOST FISHES IN THE EASTERN BERING SEA By Kevin A. Siwicke RECOMMENDED: Dr. Trent Sutton / / / c ^ ■ ^/Jy^O^^- Dr. Shannon Atkinson Chair, Graduate Program in Fisheries Division APPROVED: Dr.^Michael Castellini Sciences Date WW* RELATIONSHIPS BETWEEN ANADROMOUS LAMPREYS AND THEIR HOST FISHES IN THE EASTERN BERING SEA A THESIS Presented to the Faculty of the University of Alaska Fairbanks in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE By Kevin A. Siwicke, B.S. Fairbanks, Alaska August 2014 v Abstract Arctic Lamprey Lethenteron camtschaticum and Pacific Lamprey Entosphenus tridentatus are ecologically and culturally important anadromous, parasitic species experiencing recent population declines in the North Pacific Ocean. However, a paucity of basic information on lampreys feeding in the ocean precludes an incorporation of the adult trophic phase into our understanding of lamprey population dynamics. The goal of this research was to provide insight into the marine life-history stage of Arctic and Pacific lampreys through lamprey-host interactions in the eastern Bering Sea. An analysis of two fishery-independent surveys conducted between 2002 and 2012 in the eastern Bering Sea revealed that Arctic Lampreys were captured in epipelagic waters of the inner and middle continental shelf and were associated with Pacific Herring Clupea pallasii and juvenile salmonids Oncorhynchus spp. In contrast, Pacific Lampreys were captured in benthic waters along the continental slope associated with bottom-oriented groundfish. Consistent with this analysis of fish assemblages, morphology of recently inflicted lamprey wounds observed on Pacific Cod Gadus macrocephalus was similar to morphology of Pacific Lamprey oral discs, but not that of Arctic Lamprey oral discs.

  • Lamprey, Hagfish
    Agnatha - Lamprey, Kingdom: Animalia Phylum: Chordata Super Class: Agnatha Hagfish Agnatha are jawless fish. Lampreys and hagfish are in this class. Members of the agnatha class are probably the earliest vertebrates. Scientists have found fossils of agnathan species from the late Cambrian Period that occurred 500 million years ago. Members of this class of fish don't have paired fins or a stomach. Adults and larvae have a notochord. A notochord is a flexible rod-like cord of cells that provides the main support for the body of an organism during its embryonic stage. A notochord is found in all chordates. Most agnathans have a skeleton made of cartilage and seven or more paired gill pockets. They have a light sensitive pineal eye. A pineal eye is a third eye in front of the pineal gland. Fertilization of eggs takes place outside the body. The lamprey looks like an eel, but it has a jawless sucking mouth that it attaches to a fish. It is a parasite and sucks tissue and fluids out of the fish it is attached to. The lamprey's mouth has a ring of cartilage that supports it and rows of horny teeth that it uses to latch on to a fish. Lampreys are found in temperate rivers and coastal seas and can range in size from 5 to 40 inches. Lampreys begin their lives as freshwater larvae. In the larval stage, lamprey usually are found on muddy river and lake bottoms where they filter feed on microorganisms. The larval stage can last as long as seven years! At the end of the larval state, the lamprey changes into an eel- like creature that swims and usually attaches itself to a fish.

    Tribal Pacific Lamprey Columbia River Inter-Tribal Fish Restorationfor the Columbia River Plan Basin Commission December 19, 2011 Nez Perce · Umatilla · Yakama · Warm Springs Acknowledgements This Tribal Pacific Lamprey Restoration Plan for the Columbia River Basin (Plan) is a product of the efforts of many tribal and non-tribal biologists, policy representatives, and independent scientists throughout the Pacific Northwest. The tribes acknowledge the collective contributions of many that offered their time and expertise to improve this tribal plan. In particular, we thank Casey Justice and Starla Roels for their extensive review of the Plan. The Plan addresses many regional comments on the draft tribal lamprey restoration plan from tribes, public utilities, federal, state and county agencies, independent scientists and the general public. These comments have greatly improved this Plan. This Plan is a living document that will be periodically updated as new information becomes available through adaptive management practices. Figure 1.

This significantly extends the range of the Ukrainian brook lamprey eastwards. The Ukrainian brook lamprey and the genus Eudontomyzon are the most distributed species and genus of the lampreys in europe, respectively. Key words: Eudontomyzon mariae, geographic distribution, Volga R. basin, Don R.basin, spawning substrate Introduction The surprising discovery of the Ukrainian brook lamprey Eudontomyzon mariae (Berg, 1931) in the elan’-kadada and Sura rivers in the volga River basin (L e v i n 2001) indicated that the geographical distribution of this species can be far more east than it has been initially assumed (H o l č í k & R e n a u d 1986).

    Guelph Ichthyology Reviews, vol. 7 (2006) 1 Bill Beamish’s Contributions to Lamprey Research and Recent Advances in the Field This paper is based on an oral presentation given at a symposium honouring Bill Beamish and his contributions to fisheries science at the Canadian Conference for Fisheries Research, in Windsor, Ontario on January 7, 2005 Margaret F. Docker Great Lakes Institute for Environmental Research, University of Windsor, Windsor, ON, N9B 3P4, Canada Current Address: Department of Zoology, University of Manitoba, Winnipeg, MB, R3T 2N2, Canada (e-mail: [email protected]) Key Words: review, sex determination, statoliths, pheromones, reproductive endocrinology, phylogeny Guelph Ichthyology Reviews, vol. 7 (2006) 2 Synopsis Since his first lamprey paper in 1972, Bill Beamish has published more than 50 papers on numerous aspects of lamprey biology, reporting on several native lamprey species as well as the Great Lakes sea lamprey. Bill and his colleagues have contributed to our knowledge of the basic biology of larval lampreys (e.g., abundance, habitat, feeding, growth, and gonadogenesis), helped refine techniques to determine age in larvae (using statoliths, structures analogous to the teleost otolith), and studied the process of metamorphosis and the feeding and bioenergetics of juvenile (parasitic) lampreys. Current research continues to build on Bill’s contributions, and also makes many advances in novel directions. This exciting current research includes: the use of high-resolution ultrasound to study gonadogenesis and evaluate sex ratio in live larval lampreys; the elucidation of some of the exogenous and endogenous triggers of metamorphosis; examination of the neuroendocrine control of reproduction and the role of unconventional sex steroids in lampreys; the discovery of migratory and sex pheromones and their potential use in sea lamprey control; the use of molecular markers to study lamprey mating systems and phylogeny; and the renewed interest in the conservation of native lampreys.
