  • 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 Restoration Plan
    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.

  • The Punctuated Seaward Migration of Pacific Lamprey (Entosphenus
    Pagination not final (cite DOI) / Pagination provisoire (citer le DOI) 1 ARTICLE The punctuated seaward migration of Pacific lamprey (Entosphenus tridentatus): environmental cues and implications for streamflow management Damon H. Goodman, Stewart B. Reid, Nicholas A. Som, and William R. Poytress Abstract: We investigated emigration timing of juvenile Pacific lamprey (Entosphenus tridentatus) over a 10-year period in the Sacramento River, California, USA. Emigration was punctuated with 90% of macrophthalmia in daily catches of at least 50 individuals. Macrophthalmia were observed primarily between November and May, with among-year variation in median emigration date over four times that of sympatric anadromous salmon. Our best model associating catch and environmental factors included days from rain event, temperature, and streamflow. We found strong evidence for an association of catch with days from rain events, a surrogate for streamflow, with 93% of emigrants caught during an event and the two subsequent days. Emigration was more likely during nighttime during subdaily sampling after accounting for the effects of factors significantly associated with daily catch. These results emphasize the importance of natural variation in streamflow regimes and provide insight for management practices that would benefit emigrating lampreys, such as synchronizing dam releases with winter and spring storms to reduce migration time, timing diversions to avoid entrainment during emigration windows, and ensuring streamflows are sufficient to reach the ocean, thereby avoiding mass stranding events. Résumé : Nous avons étudié le moment de la migration vers la mer (émigration) de lamproies du Pacifique (Entosphenus tridentatus) juvéniles sur une période de 10 ans, dans le fleuve Sacramento (Californie, États-Unis).

  • Effects of Atrazine on Olfactory-Mediated Behaviors in Pacific Lamprey (Entosphenus Tridentatus)
    AN ABSTRACT OF THE THESIS OF April G. Smith for the degree of Master of Science in Fisheries Science presented on February 7, 2012 Title: Effects of Atrazine on Olfactory-Mediated Behaviors in Pacific Lamprey (Entosphenus tridentatus) Abstract approved: Carl B. Schreck Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to lamprey populations. Using an odorant response behavioral assay we were able to demonstrate that environmentally relevant concentrations of atrazine caused a depressed response to adult lamprey holding tank effluent, likely pheromones. Atrazine also depressed their activity level; the number of times they crossed into the effluent arm after being treated with atrazine was significantly lower than controls. In addition, activity level post exposure to atrazine differed between adult life history stages, something which was not significantly different during control trials. Using an odorant detection assay, based on evaluating ventilation rate, we were able to show that environmentally relevant concentrations of atrazine caused a significant increase in ventilatory response to a repulsive odorant, a conspecific necromone. Through the detection study we also showed that lamprey, exposed to atrazine, had a slight increase in ventilatory response to odor from adult lamprey. If we are concerned about the decline in Pacific lamprey populations, then we should logically be concerned with their exposure to atrazine in the environment. © Copyright by April G.
