Carotenoid pigments in chum salmon - II. Behavior of carotenoids in the chum salmon Oncorhynchus keta during development.

open access: yesNIPPON SUISAN GAKKAISHI, 1984
As part of the historical study of carotenoids in the chum salmon, the behavior of carotenoids was investigated duing development. The carotenoids which were stored in the eggs during the anadromous migration period, stayed in a constant quantitative (0.677-0.687mg/100g) and compostion ratio, with a 76-80% astaxabthin rate, until hatching.

Motives and barriers to blood donation among adults aged over 50 years: A qualitative analysis

open access: yesTransfusion Medicine, EarlyView.
Abstract Background Ageing populations will increase demand for blood‐products and donors who supply them. While blood collection agencies (BCAs) typically target younger people to expand supply, recruiting donors aged 50+ is also a potential solution. However, few studies focus exclusively on this group.

Reciprocal subsidies and food web pathways leading to chum salmon fry in a temperate marine-terrestrial ecotone. [PDF]

open access: yesPLoS ONE, 2010
Stable isotope analysis was used to determine the relative proportions of terrestrial and marine subsidies of carbon to invertebrates along a tidal gradient (low-intertidal, mid-intertidal, high-intertidal, supralittoral) and to determine the relative ...

Amino acid composition of chum salmon gonadotropin.

open access: yesNIPPON SUISAN GAKKAISHI, 1977
The amino acid composition of chum salmon gonadotropin (s-GTH) was compared with that of carp gonadotropin (c-GTH). S-GTH has more glutamic acid and less valine and tyrosine than c-GTH. Moreover s-GTH was compared with the mammalian gonadotropins. S-GTH resembled ovine follicle stimulating hormone (o-FSH) in the number of histidine, arginine, aspartic ...

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1749-1765, July 2026.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Beyond lethal temperatures: Factors behind the disappearance of chum salmon from their southern margins under climate change.

open access: yesPLoS ONE
The Tone River in Japan represents one of the southern limit distributions of chum salmon (Oncorhynchus keta) on the western side of the North Pacific, but the number of adult chum salmon observed here has declined dramatically since 2013 and reached ...

Monitoring of salmon reproduction on spawning grounds in the Amur River in 2017–2024

open access: yesИзвестия ТИНРО
Reproduction of pacific salmon in the Amur River basin was monitored during 8 years using standard methods of fisheries science. The data indicate weak reproduction of pink salmon and the summer and fall chum salmon. Distribution density of the fall chum

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.
