Meiotic maps of sockeye salmon derived from massively parallel DNA sequencing

open access: yesBMC Genomics, 2012
Background Meiotic maps are a key tool for comparative genomics and association mapping studies. Next-generation sequencing and genotyping by sequencing are speeding the processes of SNP discovery and the development of new genetic tools, including ...

Sockeye salmon of Iturup Island: characteristics of spawners from commercial catches in 2021

open access: yesИзвестия ТИНРО, 2022
Spawners of sockeye salmon caught in northern Iturup and in the Prostor Bay and Kurilsky Bay in July-August, 2021 are investigated. Almost all of them had the age 1.2+ or 1.3+, with prominent prevalence of the former both for females (88.9 %) and males ...

Feeding habits of pacific salmons in the eastern Bering Sea in 2003-2012

open access: yesИзвестия ТИНРО, 2015
Change in prey for pacific salmons in the eastern Bering Sea is considered between the periods of relatively warm (2003-2006) and relatively cold (2007-2012) conditions on the base of data obtained in the frames of BASIS research program.

Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

Maintenance of Genetic Diversity in Natural Spawning of Captively-Reared Endangered Sockeye Salmon, Oncorhynchus nerka

open access: yesDiversity, 2014
Captive propagation of Pacific salmon is routine, but few captive breeding programs have been conducted to successfully re-establish extirpated wild populations.

Detecting changes in distribution and abundance using harvest data in two sympatric bear species in Southeast Alaska

open access: yesWildlife Biology, EarlyView.
Monitoring wildlife populations in remote landscapes is challenging due to the difficulties of conducting field surveys. However, harvest data, which are routinely collected by management agencies, offer valuable insights into population trends. Brown bear Ursus arctosand American black bear U.

Ecological considerations for reintroducing Chinook salmon upstream of Shasta Dam

open access: yesConservation Science and Practice, EarlyView.
In this assessment, we reviewed existing literature to assess the ecological risks, benefits, and uncertainties associated with reintroducing Chinook salmon into the McCloud River, a tributary of the Sacramento River, California. We identified considerations related to population viability, disease, and species interactions.

Stock-recruitment models, principles of management and rules for regulating the fishery on the main Chukotka stocks of sockeye and chum salmon

open access: yesИзвестия ТИНРО, 2021
Fishery pressure on populations of pacific salmons has increased in the Rusian Far East in the last decade because of growing fishing and processing capacity, so measures for the fishery regulation are necessary, as the regime of pass days in rivers and ...

Investigating the Dynamics of Sex‐Structured Stock Assessment Models Under Sexual Size Dimorphism

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The integration of separate sexes in stock assessment models represents an advancement towards more realistic modeling of interactions between fisheries and target species. However, increased model complexity can also introduce additional uncertainty into the modeling process.

Juvenile salmon usage of the Skeena River estuary.

open access: yesPLoS ONE, 2015
Migratory salmon transit estuary habitats on their way out to the ocean but this phase of their life cycle is more poorly understood than other phases. The estuaries of large river systems in particular may support many populations and several species of
