First Record of a Coregonid Fish Species, Coregenus Albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake Shared Between Turkey and Georgia
J. Black Sea/Mediterranean Environment Vol. 25, No. 3: 325-332 (2019) SHORT COMMUNICATION First record of a coregonid fish species, Coregenus albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake shared between Turkey and Georgia Sedat V. Yerli Department of Biology, Hacettepe University, SAL, Beytepe, Ankara, TURKEY Corresponding author: [email protected] Abstract The genus Coregenus (Salmoniformes: Salmonidae) was recently considered not to be represented in Turkey. European cisco or vendace, Coregonus albula (Linnaeus, 1758) was reported for the first time for Turkey in this article with fifteen samples in Aktaş Lake, Ardahan. This species should be added to the checklist of Turkish fish fauna. Turkish name is proposed as “Akbalık” for this species. Keywords: Coregonus albula, first record, Aktaş Lake, Kartsakhi, alkaline lake, Georgia, Turkey Received: 30.10.2019, Accepted: 26.11.2019 Vendace or European cisco Coregonus albula (Linnaeus, 1758) is a native species for northern Europe. Berg (1948) reported the distribution of this species its morphological measurements in the former USSR and adjacent countries. Froese and Pauly (2019) summarized the natural distribution of vendace as Baltic basin, several lakes of upper Volga drainage; some lakes of White Sea basin and North Sea basin east of Elbe drainage; anadromous in Gulf of Finland and marine in northernmost freshened part of Gulf of Bothnia between Finland and Sweden; in Lake Inari, northern Finland; lower Rhine (now extirpated). The vendace was introduced, intentionally in some countries in Europe and United States of America. Vendace was introduced in 1959, 1982-1987 in the Irtysh River Basin and in 1960-61 in Lake Balkhash in Kazakhstan (Mitrofanov and Petr 1999). -

Compendium of Research in the Northwest Territories 2014
Compendium of Research in the Northwest Territories 2014 www.nwtresearch.com This publication is a collaboration between the Aurora Research Institute, the Department of Environment and Natural Resources, Fisheries and Oceans Canada and the Prince of Wales Northern Heritage Centre. Thank you to all who submitted a summary of research or photographs, and helped make this publication possible. Editor: Ashley Mercer Copyright © 2015 ISSN: 1205-3910 Printed by Aurora Research Institute Foreword Welcome to the 2014 Compendium of Research in the Northwest Territories. This year marked a special anniversary for the Aurora Research Institute and northern research. Fifty years ago, the Inuvik Research Laboratory was built and has served as a hub for research in the western arctic ever since. The Lab, as it was known, was first built as an initiative of the Canadian federal government in the newly established community of Inuvik. It remains on the same site today, but in 2011, a new modern multi-purpose facility opened to continue to support research in the north. We have included a brief history of the Lab and its impact in this edition of the Compendium to mark its long lasting importance to many researchers and community members. As part of the 50th anniversary celebration, the Aurora Research Institute team undertook a full set of NWT-wide celebrations. We celebrated the history, capacity and growth of research in the NWT that touched all corners of the territory and beyond. We honoured the significant scientific contributions that have taken place in the NWT over the past 50 years, and the role of NWT researchers, technicians and citizens in these accomplishments. -

The Canadian Arctic Expedition 1913 – 18 and Early Advances in Arctic Vertebrate Zoology Kamal Khidas1
ARCTIC VOL. 68, NO. 3 (SEPTEMBER 2015) P. 283 – 292 http://dx.doi.org/10.14430/arctic4505 The Canadian Arctic Expedition 1913 – 18 and Early Advances in Arctic Vertebrate Zoology Kamal Khidas1 (Received 4 April 2014; accepted in revised form 5 November 2014) ABSTRACT. A century ago, an international team of scientists sailed under the Canadian flag to the western Canadian Arctic, via the Bering Strait, to achieve the goals of the Canadian Arctic Expedition of 1913 – 18. This major expedition was a milestone in the history of Canada. The scientists explored a vast, unknown sea and land area that extended from the Alaskan northern coast to Bathurst Inlet in Canada, and from Meighen Island to approximately 160 – 200 km inland from the continental coasts. This area had never been explored by an expedition before, and many parts of it had never been visited (except, presumably, by Inuit and their ancestors). The expedition resulted in a remarkable harvest of terrestrial and marine plants and animals, and associated data. The scientists furthered geographic and scientific knowledge of the Arctic and published 74 reports in various scientific fields, yet none of these addressed vertebrate zoology. The present report attempts to make up for this deficiency. Overall, the CAE collected and preserved 2084 vertebrate specimens and inventoried 139 species, which together fairly depicted the Arctic vertebrate community. Almost all specimens are preserved at the Canadian Museum of Nature. They significantly supplemented the rather meagre vertebrate collections of the Museum of those times and have since prompted the continuing development of these collections.

Most natural surface fresh waters have an ammonia concentration of less than 0.1 mg/L (as nitrogen), which is consistent for all of the lakes tested (Puznicki 1996). The Yellowknife River sampling location did not include ammonia in the suite of parameters analyzed. 2.9.5.3 Metals Alum inum Aluminum concentrations in fresh surface waters are pH dependent. The majority of lakes located between Great Slave Lake and the Beaufort Sea that were tested for aluminum displayed values below 100 μg/L (ppb) and a pH of greater than 6.5 (Figure 2.9-5 and 2.9-2, respectively), indicating they did not exceed the CCME guideline for the protection of DTXDWLFOLIHIRUDOXPLQXP VHWDWJ/DWS+ &HUWDLQODNHVZLWKVOLJKWO\ORZHUS+ levels (e.g., 5.5-6.5, Figure 2.9-2) had corresponding aluminum levels that would be considered in excess of the lower CCME guideline of 5 μg/L at these lower pH levels (e.g., <6.5). Lakes within the watersheds of the Yellowknife River displayed even lower aluminum concentrations than many of the lakes tested in other areas. -
Spawning Distribution of Bering Ciscoes in the Yukon River
Transactions of the American Fisheries Society 144:292–299, 2015 American Fisheries Society 2015 ISSN: 0002-8487 print / 1548-8659 online DOI: 10.1080/00028487.2014.988881 ARTICLE Spawning Distribution of Bering Ciscoes in the Yukon River Randy J. Brown* and David W. Daum1 U.S. Fish and Wildlife Service, 101 12th Avenue, Room 110, Fairbanks, Alaska 99701, USA Abstract Bering Ciscoes Coregonus laurettae are anadromous salmonids with known spawning populations only in the Yukon, Kuskokwim, and Susitna rivers in Alaska. A commercial fishery for the species was recently initiated at the mouth of the Yukon River, inspiring a series of research projects to enhance our understanding of the exploited population. This study was designed to delineate the geographic spawning distribution of Bering Ciscoes in the Yukon River. One hundred radio transmitters per year in 2012 and 2013 were deployed in prespawning Bering Ciscoes at a site located 1,176 km upstream from the sea. A total of 160 fish survived fish wheel capture and tagging, avoided harvest and predation after tagging, and continued migrating upstream to their spawning destinations. Approximately 79% migrated to spawn in the upper Yukon Flats, upstream from the mouth of the Porcupine River, and 21% migrated to spawn in the lower Yukon Flats. Locating the Bering Cisco spawning area, which is almost entirely encompassed by the Yukon Flats National Wildlife Refuge, enhances our ability to protect it from anthropogenic disturbance and enables future biological research on the spawning population. Conservation of migratory fish in large rivers requires an removing gravel from fish spawning habitats has been shown understanding of habitat use across a species’ range and the to reduce spawning success (Fudge and Bodaly 1984; Meng ability to manage anthropogenic impacts to essential habitats and Muller€ 1988), which could jeopardize the viability of such as migration routes and spawning areas (Gross 1987; affected populations. -

The overall goal ofthe AES is to preserve and enhance the integrity, health, biodiversity and productivity ofour Arctic ecosystems for the benefit ofpresent and future generations. Four specific programs address some ofthe key environmental challenges: they are waste cleanup, contaminants, water management, and environment and economy integration. The programs are managed by the Northern Affairs Program ofthe Department of Indian Affairs and Northern Development (DIAND); however, there is a strong emphasis on partnerships with northern stakeholders including Native organizations, other federal departments and the territorial governments. The AES Action on Water Program specifically strives to enhance the protection ofnorthern freshwaters through improved knowledge and decision-making. Water Resources managers in the Yukon and the Northwest Territories administer this Program which focuses on freshwater aquatic ecosystems. This report is the first detailed compilation ofstudies.conducted under the AES Action on Water Program. It covers work done from 1991 to 1994. Many studies have been concluded, while others are ongoing. Although data may not be available for all studies, or results are preliminary at this time, this report presents detailed background, objectives and methodology. -
Farmed Nelma (Stenodus Leucichthys) Is Susceptible to Flavobacteria
Farmed nelma (Stenodus leucichthys) is susceptible to flavobacteria Satu Viljamaa-Dirks¹, Henry Kuronen¹ & Risto Kannel² 1 Finnish Food Safety Authority Evira, PL 92, 70701 Kuopio, Finland 2 Finnish Game and Fisheries Institute, Vilppulantie 415, 41360 Laukaa, Finland Correspondence: [email protected] Abstract Nelma, Stenodus leucichthys nelma (Pallas 1773), is a migratory coregonid originating from North American and Siberian rivers [1–3]. Another subspecies Stenodus leucichthys leucichthys (Güldenstädt 1772) lives in the tributaries of the Caspian Sea. Adult weight is expected to be 15–25 kg and the fish is growing quickly also at low temperatures [4], which would make it a desirable cultured species in northern countries. An experimental batch was therefore imported to Finland in the spring of 2010 from Russia, where a brood stock is held in a fish farm in North-West Russia. Nelma was imported as eggs to a quarantine facility in an inland fish farm. The quarantine was a separate hall containing several glass fiber tanks. The facility was using surface water and the effluent water was treated with UV and peracetic acid before release. It appeared impossible to get suitable samples of the brood stock in Russia to ensure health status similar to the Finnish inland area. Instead, hatchlings and fry were controlled several times for viral and bacterial infections using standard bacteriological and virological methods [5]. In addition, rainbow trout (Oncorhynchus mykiss) and arctic charr (Salvelinus alpinus) were used as sentinels, and examined for the presence of viruses and bacteria after being kept in the effluent water of the nelma fry for two months.
