Download or read book Radio Telemetry Studies of Arctic Grayling Migrations to Overwinter Spawning and Summer Feeding Areas in the Parsnip River Watershed 1996 97 written by and published by . This book was released on 2002 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report concerns part of a program to conserve & restore Arctic grayling stocks & habitat in the Williston watershed of British Columbia. It describes a study conducted to determine migratory patterns, overwinter distribution & habitat, and spawning areas & habitats of Arctic grayling in the Table & Anzac rivers, both tributaries of the Parsnip River. In the study, 55 grayling were captured, surgically implanted with radio transmitters, and released back into the Table & Anzac rivers. The fish were tracked by aerial radio telemetry on a monthly basis during the winter of 1996-97 to identify overwinter locations and on a biweekly basis in April once migrations had started. Tracking flight frequency was increased to weekly during the suspected spawning period (May & June) and then monthly until October. In addition, underwater surveys were conducted in September to verify conditions of tagged fish. Results are presented & discussed regarding survival rates; migrations to overwintering, spawning, & summer feeding areas; and spawning area characteristics. The final section discusses management implications based on the findings.

Download or read book Hungry Hollow Creek Arctic Grayling Telemetry written by Corey J. Schwanke and published by . This book was released on 2020 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study will describe the seasonal distribution of Arctic grayling Thymallus arcticus captured in Hungry Hollow Creek of the Middle Fork Gulkana River during summer. Arctic grayling will be captured using hook-and-line gear in mid-July. One hundred adult Arctic grayling ≥320 mm FL will be surgically implanted with radio tags that will operate for ~17 months. Radiotagged Arctic grayling will be tracked throughout the year to determine overall distribution, including overwintering, spawning, and summering areas, as well as migration timing among these locations. The seasonal proportion of the tagged fish residing in Hungry Hollow Creak and the mainstem of the Gulkana River will also be estimated.
Download or read book Beaver and Nome Creeks Arctic Grayling Radiotelemetry 2021 2022 written by Lisa Ann Stuby and published by . This book was released on 2021 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project plan outlines a 2-year radiotelemetry study for Arctic grayling Thymallus arcticus in the Beaver Creek drainage. Information on life history, migration timing, and habitat use is needed to better understand the distribution of Arctic grayling during critical time periods and to inform a future population assessment. Radio transmitters with a 2-year operational life will be surgically implanted into 150 Arctic grayling in parts of the drainage that are most susceptible to sport fishing pressure. Aerial tracking flights to locate radiotagged Arctic grayling will be conducted during winter, spring, summer, and fall in order to identify, document, and characterize overwintering, spring spawning, and summer feeding areas. Location data will also be used to examine seasonal fidelity to these areas. Seasonal migration timing between Beaver Creek and its Nome Creek tributary will be determined with a stationary tracking station located near the confluence. Results from the radiotelemetry study will be used to select an appropriate index area and time for a mark-recapture experiment that will be conducted during summer 2023.

Download or read book Seasonal Distribution of Arctic Grayling Summering in Hungry Hollow Creek Gulkana River written by Corey J. Schwanke and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gulkana River Arctic grayling Thymallus arcticus were radiotagged in July 2020 and tracked for the following 15 months to describe seasonal distributions, migration patterns, and to identify spawning areas. Radio tags were surgically implanted into 100 Arctic grayling ≥320 mm FL in the lower 6 river kilometers (RKM) of Hungry Hollow Creek, located in the Middle Fork Gulkana River drainage. A total of 8 aerial tracking surveys were flown from 29 September 2020 through 14 October 2021, and a fixed tracking station was installed below the confluence of Hungry Hollow Creek and the Middle Fork Gulkana River. Arctic grayling located during tracking surveys exhibited strong migratory patterns. The general seasonal movements of radiotagged fish were extensive, with all radiotagged fish leaving Hungry Hollow Creek in late summer or fall and migrating downstream for overwintering. All fish that survived the winter left Hungry Hollow Creek from 16 July–7 October 2020, and had a mean date of passage of 1 September. Radiotagged fish remained stationary for most of the winter before generally moving upstream in spring for spawning, then moving even further upstream for summering. Fish that survived a full year had a mean home range of 85.2 RKM and a maximum home range of 137.6 RKM. The radiotagged Arctic grayling in this study dispersed throughout the drainage for overwintering and spawning, representing most previously documented seasonal use areas and reinforcing the importance of this small reach of river to the population.

This book was released on 2019 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gulkana River Arctic grayling Thymallus arcticus were radiotagged in fall 2016 and tracked for the following 14 months to describe seasonal distributions, migration patterns, and to identify spawning areas. Radio tags were surgically implanted into 126 Arctic grayling ≥320 mm fork length (FL) in a 64.5 river kilometer (rkm) reach of the Gulkana River mainstem from the confluence of the Middle Fork Gulkana River down to a point approximately 5 rkm above Sourdough Creek. A total of 15 aerial tracking surveys were flown from 7 November 2016 through 3 November 2017. Arctic grayling located during tracking surveys exhibited migratory behavior. Fish that survived a full year had a mean home range of 60.9 rkm and 8 fish had home ranges >100 rkm. Migrations for spawning were generally upstream and began in early May. Most fish made post spawning movements upriver to summering locations in June and July, then downstream migrations to overwintering areas starting in August. Several new spawning areas were documented with Stump Creek and the West Fork Gulkana River being the most significant. Radiotagged fish were also present in other smaller unnamed tributaries around the West Fork Gulkana River confluence during the spawning period. Already recognized spawning tributaries such as the Middle Fork Gulkana River, Twelvemile Creek, and Sourdough Creek had radiotagged Arctic grayling in them during the spawning period, but Poplar Grove did not.
