Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

open access: yesJournal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Flexural properties of the equine hoof wall [PDF]

open access: yes, 2007
The equine hoof wall is a hard keratinous structure which transmits forces generated when the hoof contacts the ground to the skeleton of the horse. During locomotion, the hoof capsule is known to yield under impact resulting in an inward curvature of ...

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Salvelino - Salvelinus fontinalis (Mitchill, 1814)

open access: yes, 2019
Aunque presenta morfología típica de los salmónidos, se diferencia de las otras especies por tener: (i) los dientes palatinos y del vómer separados, (ii) aletas pectorales, pélvicas y anal con una línea marginal blanca y (iii) entre 9 y 19 branquiespinas (Kottelat y Freyhof, 2007).

Complete mitochondrial genome of the Salvelinus malma sp. (Salmoniformes, Salmonidae) with phylogenetic consideration

open access: yesMitochondrial DNA. Part B. Resources, 2017
The complete mitochondrial genome sequence of Chinese native Dolly Varden (Salvelinus malma sp.) was sequenced. It was 16,652-nucleotide in length and consisted of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 2 non-coding ...

Electrical phase angle as a new method to measure fish condition [PDF]

open access: yes, 2009
In this study, phase angle (the ratio of resistance and reactance of tissue to applied electrical current) is presented as a possible new method to measure fish condition.

First Report of the Malacosporean Parasite Tetracapsuloides bryosalmonae in the Faroe Islands Reveals Widespread Distribution and High Prevalence in Brown Trout

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT The myxozoan endoparasite Tetracapsuloides bryosalmonae (Tb), the causative agent of proliferative kidney disease (PKD) in salmonids, has predominantly been reported in temperate regions of continental Europe and North America. Here, we present the first record of Tb in the Faroe Islands, extending the known northern distribution of the ...

The complete sequence of the mitochondrial genome of the Chinook salmon, Oncorhynchus tshawytscha

open access: yesBiological Research, 2003
The complete sequence of the mitochondrial genome of Chinook salmon, Oncorhynchus tshawytscha, has been determined. The circular genome consisting of 16,644 base pairs encodes thirteen proteins, the 12S and 16S ribosomal RNAs, and 22 transfer RNAs. These
