Comparison between the distributions of land-locked Atlantic salmon Salmo salar L. and three-spined stickleback Gasterosteus aculeatus L. in the river Namsen, Norway

open access: yesFauna Norvegica, 1984
The land-locked salmon Salmo salar L. in the river Namsen is found up-stream to a waterfall situated 290 m above s.l. It is found both above and below the Trongfoss waterfall in the main river. The three-spined stickleback Gasterosteus aculeatus L.

Complete mitochondrial genome of the white char Salvelinus albus (Salmoniformes, Salmonidae) [PDF]

open access: yesMitochondrial DNA Part A, 2015
The complete mitochondrial genome was sequenced in two individuals of white char Salvelinus albus. The genome sequences are 16 653 bp in size, and the gene arrangement, composition, and size are very similar to the salmonid fish genomes published previously. The low level of sequence divergence detected between the genome of S.

Life history of a riverine, resident Atlantic salmon Salmo salar L.

open access: yesFauna Norvegica, 1988
The Mellingselva river, a tributary of the River Namsen, in central Norway, supports a population of freshwater resident Atlantic salmon (Salmo salar), which resembles a parr and which completes its entire life cycle in the river.

Bony fish genomes: Status and gaps

open access: yesJournal of Fish Biology, Volume 109, Issue 2, Page 631-649, August 2026.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Mechanisms of co-existence of Heterocope saliens (Crustacea, Copepoda) and planktivorous fish

open access: yesFauna Norvegica, 1984
The simultaneous occurrence of Heterocope saliens and a large stock of Arctic char was investigated in the oligotrophic, coastal Lake Selura in SW Norway. Habitat-overlap of H. saliens and Arctic char was restricted mainly to June.

Semi‐automated MicroED system unveils multiple polymorphs in fish‐derived guanine crystals

open access: yesActa Crystallographica Section C, Volume 82, Issue 7, Page 310-323, July 2026.
A semi‐automated MicroED data collection and processing system was established and shown to be suitable for the structural investigation of submicrometer‐scale biogenic crystals.Certain fish display silvery or blue colour, not through pigments, but through specialized guanine crystals that exist within iridophore cells in their skin. Within these cells,

Bird predation on hatchery reared Atlantic salmon smolts, Salmo salar L., released in the River Eira, Norway

open access: yesFauna Norvegica, 1987
Carlin-tagged Atlantic salmon smolts have been released in the River Eira in western Norway during the period 1961 - 1980. Just after release birds were observed as smolt predators.

Diurnal variations in the diet of 0 to 3 years old Atlantic salmon Salmo salar L. under semiarctic summer conditions in the Alta River, Northern Norway

open access: yesFauna Norvegica, 1986
The stomach contents of 0 to 3 year old salmon were investigated throughout a single 20 hour period in each of July, August and September 1981. There was no marked diurnal variation in stomach content of fry, while that of parr indicated nocturnal ...
