Oncorhynchus mykiss
A large stout-bodied, sometimes anadromous, TROUT found in still and flowing waters of the Pacific coast from southern California to Alaska. It has a greenish back, a whitish belly, and pink, red, or lavender stripes on the sides, with usually a sprinkling of black dots. It is highly regarded as a sport and food fish. Its former name was Salmo gairdneri. The sea-run rainbow trouts are often called steelheads. Redband trouts refer to interior populations of rainbows.
Oncorhynchus
A genus of the family SALMONIDAE (salmons and trouts). They are named for their hooked (onco) nose (rhynchus). They are usually anadromous and occasionally inhabit freshwater. They can be found in North Pacific coastal areas from Japan to California and adjacent parts of the Arctic Ocean. Salmon and trout are popular game and food fish. Various species figure heavily in genetic, metabolism, and hormone research.
Oncorhynchus kisutch
Fish Diseases
Salmon
Fish of the genera ONCORHYNCHUS and Salmo in the family SALMONIDAE. They are anadromous game fish, frequenting the coastal waters of both the North Atlantic and Pacific. They are known for their gameness as a sport fish and for the quality of their flesh as a table fish. (Webster, 3d ed).
Oncorhynchus keta
An anadromous species of SALMON found in the streams of the Pacific coast from Sacramento north, and also common in Japan. It is used frequently in genetic and other medical research.
Protozoan Infections, Animal
Gills
Paired respiratory organs of fishes and some amphibians that are analogous to lungs. They are richly supplied with blood vessels by which oxygen and carbon dioxide are exchanged directly with the environment.
Trout
Various fish of the family SALMONIDAE, usually smaller than salmon. They are mostly restricted to cool clear freshwater. Some are anadromous. They are highly regarded for their handsome colors, rich well-flavored flesh, and gameness as an angling fish. The genera Salvelinus, Salmo, and ONCORHYNCHUS have been introduced virtually throughout the world.

Novirhabdovirus
A genus in the family RHABDOVIRIDAE, infecting numerous species of fish with broad geographic distribution. The type species is INFECTIOUS HEMATOPOIETIC NECROSIS VIRUS.
Rhabdoviridae Infections
Virus diseases caused by RHABDOVIRIDAE. Important infections include RABIES; EPHEMERAL FEVER; and vesicular stomatitis.

Flavobacterium
Fish Proteins
Proteins obtained from species of fish (FISHES).
Yersinia ruckeri
A species of gram-negative bacteria responsible for red mouth disease in rainbow trout (ONCORHYNCHUS MYKISS). The bacteria is a natural component of fresh water ecosystems in the United States and Canada.
Myxozoa
Hemorrhagic Septicemia, Viral
A systemic infection of various salmonid and a few nonsalmonid fishes caused by Viral hemorrhagic septicemia virus (see NOVIRHABDOVIRUS),

Salmo salar
A commercially important species of SALMON in the family SALMONIDAE, order SALMONIFORMES, which occurs in the North Atlantic.
Infectious hematopoietic necrosis virus
The type species of NOVIRHABDOVIRUS, in the family RHABDOVIRIDAE. It is a major pathogen of TROUT and SALMON.
Rhabdoviridae
A family of bullet-shaped viruses of the order MONONEGAVIRALES, infecting vertebrates, arthropods, protozoa, and plants. Genera include VESICULOVIRUS; LYSSAVIRUS; EPHEMEROVIRUS; NOVIRHABDOVIRUS; Cytorhabdovirus; and Nucleorhabdovirus.
Kinetoplastida
Furunculosis
Cestode Infections
Infections with true tapeworms of the helminth subclass CESTODA.
Diplomonadida
A group of flagellated, mostly symbiotic EUKARYOTES characterized by twofold symmetry associated with the presence of a pair of karyomastigont organellar systems. Two nuclei are attached by fibers to the flagella and there are no MITOCHONDRIA. Diplomonadida were formerly members of the class Zoomastigophora in the old five kingdom paradigm.
Vitellogenesis
The active production and accumulation of VITELLINS (egg yolk proteins) in the non-mammalian OOCYTES from circulating precursors, VITELLOGENINS. Vitellogenesis usually begins after the first MEIOSIS and is regulated by estrogenic hormones.
Head Kidney
Protozoan Infections
Vitellogenins
Phospholipoglycoproteins produced in the fat body of egg-laying animals such as non-mammalian VERTEBRATES; ARTHROPODS; and others. Vitellogenins are secreted into the HEMOLYMPH, and taken into the OOCYTES by receptor-mediated ENDOCYTOSIS to form the major yolk proteins, VITELLINS. Vitellogenin production is under the regulation of steroid hormones, such as ESTRADIOL and JUVENILE HORMONES in insects.
Bryozoa
Carps
Fresh Water
Water containing no significant amounts of salts, such as water from RIVERS and LAKES.
Swimming
An activity in which the body is propelled through water by specific movement of the arms and/or the legs. Swimming as propulsion through water by the movement of limbs, tail, or fins of animals is often studied as a form of PHYSICAL EXERTION or endurance.
Eukaryota
One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.

Copepoda
A huge subclass of mostly marine CRUSTACEA, containing over 14,000 species. The 10 orders comprise both planktonic and benthic organisms, and include both free-living and parasitic forms. Planktonic copepods form the principle link between PHYTOPLANKTON and the higher trophic levels of the marine food chains.

Yersinia Infections
Infections with bacteria of the genus YERSINIA.
Species Specificity
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

Sequence Alignment
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
