The salmonids (family: Salmonidae).

2010
As a taxon, the salmonids comprise 11 genera, with 65-70 species. All species occur naturally in the northern hemisphere but several salmonid species have been introduced to the southern hemisphere, where they often form the basis of sport fisheries or aquaculture enterprises.

Comments on the Nomenclature of Some Subgenera of Salmonidae

Journal of the Fisheries Research Board of Canada, 1972
Nomenclatural problems in some subgenera of Salmonidae are cleared away with the diagnoses of three new subgenera, viz: Parahucho Vladykov, Parasalmo Vladykov, and Rhabdofario Cope.

Intra- and interspecific genome-size variation in the Salmonidae

Cytogenetic and Genome Research, 1992
The nuclear DNA contents of 22 salmonid taxa, estimated primarily by flow-cytometric analysis relative to a chicken internal standard, were evaluated to compare intra- and interspecific variation in DNA content within this fish family. The average variability within taxa exceeded that among taxa. Intraspecific genome-size variation was substantial and,

HPLC Quantification of astaxanthin and canthaxanthin in Salmonidae eggs

Biomedical Chromatography, 2016
AbstractAstaxanthin and canthaxanthin are naturally occurring antioxidants referred to as xanthophylls. They are used as food additives in fish farms to improve the organoleptic qualities of salmonid products and to prevent reproductive diseases. This study reports the development and single‐laboratory validation of a rapid method for quantification of

A study of achromatic regions in species of Salmonidae and Esocidae

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973
Abstract 1. 1. An oxidase found in achromatic regions on tetrazolium stained gels is described electrophoretically from various species of trout. 2. 2. The enzyme was stained with and without the use of the substrate G-6-P or 6-PG. 3. 3. The results indicate that the enzyme is apparently a dimer as a 1 : 1 ratio of triple : single handed ...

EFFECT OF THYROID PREPARATIONS AND IODIDE ON SALMONIDAE¹

Endocrinology, 1952
UNTIL recently, the common belief was that, in fish, the thyroid hormone did not have a metabolic effect similar to the one observed in mammals, or even that it had no effect at all. Thus, Etkin and his collaborators were unable to detect any effect of thyroid extract or thyroxine administration on the oxygen consumption of the goldfish, Carassius ...

sex determination and sex control in salmonidae

2018
The Salmonidae family comprises three sub‐families (Coregoninae, Thymallinae and Salmoninae), with 11 genera and about 66 species. Salmonid farming has grown considerably in the last fifty years, with Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) being the main farmed species, and with an increasing production of large size fish

Exon and Intron Variability in Salmonidae Growth Hormone Genes

Molecular Biology, 2020
Gene duplication is one of the main mechanisms of formation of new genetic material in evolution. The occurrence of a gene duplication is believed to relax selection pressure on one of the copies. Consequently, this gene accumulates mutations at a higher rate, and over time it acquires a new function.

Blood Group Antibodies in Salmonidae Roe

Vox Sanguinis, 1971
SummaryExtracts from roe of female brown trout, rainbow trout, seatrout and salmon are found to give reactions of saline agglutinating anti‐B with human red cells. Some trout roe also contain saline agglutinating anti‐A and/or anti‐AB.
