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.

Simple dynamics underlie sockeye salmon (Oncorhynchus nerka) cycles [PDF]

open access: yesCanadian Journal of Fisheries and Aquatic Sciences, 1998
A variety of mechanisms have been proposed to explain the renowned British Columbia sockeye salmon (Oncorhynchus nerka) cycles, most of which invoke between-brood interactions (delayed density dependence) or depensatory harvest practices. We examine the dynamics of the Ricker model with realistic parameter values and suggest that the cycles could ...

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.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]

open access: yes, 1988
Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

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 ...
