Nonlethal Tools to Identify Mass Ovarian Follicular Atresia in Burbot
Autor: Lauren M. McGarvey, Jason E. Ilgen, Christopher S. Guy, Jason G. McLellan, Molly A.H. Webb
Publikováno v: Journal of Fish and Wildlife Management. 13:552-561
Skipped spawning, or variation in spawning periodicity, occurs in many annual spawning fish species and is an important consideration for population management. We assessed plasma sex steroid concentrations and measured gonad size and ovarian follicl

Competition overwhelms environment and genetic effects on growth rates of endangered white sturgeon from a conservation aquaculture program
Autor: James A. Crossman, Josh Korman, Jason G. McLellan, Matthew D. Howell, Andy L. Miller
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences.
Improving the status of endangered species can be challenging because the efficacy of conservation actions is often uncertain. Conservation aquaculture has been the main recovery action for endangered white sturgeon ( Acipenser transmontanus) in the

Gonad Size Measured by Ultrasound to Assign Stage of Maturity in Burbot
Autor: Lauren M. McGarvey, Jason E. Ilgen, Christopher S. Guy, Jason G. McLellan, Molly A. H. Webb
Publikováno v: Journal of Fish and Wildlife Management. 12:241-249
We measured gonad size (diameter and circumference) by ultrasound and used it as a metric to assign stage of maturity in Burbot Lota lota from Lake Roosevelt, Washington. We collected paired gonad tissue and ultrasound measurements monthly from Novem

Estimates of Chinook Salmon Spawning Habitat in a Blocked Reach of the Columbia River Upstream of Grand Coulee Dam
Autor: Lysel Garavelli, William A. Perkins, Zannatul Haque, Matthew D. Howell, Brian J. Bellgraph, Jason G. McLellan, Marshall C. Richmond, Casey Baldwin
Publikováno v: Northwest Science. 94
Spawning habitat of Chinook salmon (Oncorhynchus tshawytscha) was estimated upstream of Grand Coulee Dam to support the feasibility evaluations of reintroducing anadromous salmon to this blocked reach of the Columbia River. A two-dimensional depth-av

Characteristics of the Kokanee Spawning Run in Harvey Creek, Washington, and its Potential Use as an Egg Source
Autor: Jason G. McLellan
Publikováno v: Northwest Science. 83:1-15
Kokanee populations often require stocking to meet fishery management goals, since natural reproduction may be limited. Many kokanee stocking programs are dependent on eggs collected from a limited number of brood lakes. The anticipated loss of the p

Use of Gill Nets for Target Verification of a Hydroacoustic Fisheries Survey and Comparison with Kokanee Spawner Escapement Estimates from a Tributary Trap
Autor: Jason G. McLellan, Casey Baldwin
Publikováno v: North American Journal of Fisheries Management. 28:1744-1757
The focus of this study was to determine whether gill nets are a valid method for assessing species composition for a hydroacoustic survey and whether the hydroacoustic and gill-net survey could be used to forecast the spawn escapement of kokanee Onc

Fine-Scale Population Structure of Rainbow Trout in the Spokane River Drainage in Relation to Hatchery Stocking and Barriers
Autor: Janet L. Loxterman, Jennifer Von Bargen, Maureen P. Small, Alice Frye, Cherril Bowman, Jason G. McLellan
Publikováno v: Transactions of the American Fisheries Society. 136:301-317
We used 13 microsatellite loci to examine population structure in rainbow trout Oncorhynchus mykiss collected from 20 tributaries and 3 main stems in the greater Spokane River drainage. Populations displayed some excess homozygosity and linkage diseq

Walleye Predation on Hatchery Releases of Kokanees and Rainbow Trout in Lake Roosevelt, Washington
Autor: Matt Polacek, Jason G. McLellan, Casey Baldwin, Keith Underwood
Publikováno v: North American Journal of Fisheries Management. 23:660-676
Recruitment failures of stocked kokanees (lacustrine sockeye salmon Oncorhynchus nerka) in Lake Roosevelt have led to examination of various limiting factors. We evaluated the predatory impacts of piscivores on hatchery-released and net-pen-released
