Seasonal changes in abundance of brown trout ( Salmo trutta ) and rainbow trout ( S. gairdnerii ) assessed by drift diving in the Rangitikei River, New Zealand

New Zealand Journal of Marine and Freshwater Research, 1985
Numbers and approximate sizes of brown trout (Salmo trutta L.) and rainbow trout (5. gairdnerii Richardson) were estimated by snorkel divers at 6 sites in the middle reaches of the Rangitikei River, North Island, New Zealand, over 14 months.

The calpastatin/calpain system in trout Salmo trutta trutta muscle

Journal of Fish Biology, 2004
Many recent reports suggest that the calpastatin/calpain system plays a role in cellular growth and differentiation. Defects of the calpastatin/calpain system have been linked to cellular dysfunctions, apoptosis, myocardial infarct, and dystrophies. The calpastatin/calpain system has also been implicated in post‐mortem tenderization of skeletal muscle ...

Overlooked aspects of the Salmo salar and Salmo trutta lifecycles

Reviews in Fish Biology and Fisheries, 2019
The salmonid lifecycle has been studied for over a 100 years. Our literature search indicated that the Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) are among the most studied of fish species. By reviewing both their anadromous and non-anadromous lifecycles, we show that there is a growing body of evidence of considerable variation in ...

The old trout Salmo trutta in the pond

Journal of Fish Biology, 2013
The last of 12 brown trout Salmo trutta stocked in a small pond in south‐east Norway in 1979 were caught in July 2011. These fish represent a curiosity regarding longevity and growth pattern, and ageing from otoliths was consistent with the known life history of this specimen.

Genetic assessment of Atlantic salmon Salmo salar and sea trout Salmo trutta stocking in a Baltic Sea river

Journal of Fish Biology, 2008
Microsatellite DNA variation was used to assess the outcome of stocking Atlantic salmon Salmo salar and migratory trout Salmo trutta in River Savara, N Sweden. No information on pre-stocking genetic composition of S. salar and S.

Smolting of two populations of Salmo trutta

Aquaculture, 1989
Abstract Smolting in two hatchery-reared populations of Salmo trutta was compared during their second winter. After a 48-h exposure to 28‰ balanced seawater, the decrease of water content in white muscle was small and mortality negligible in one stock from January till late May.

First molecular data on Eimeria truttae from brown trout (Salmo trutta)

Parasitology Research, 2019
The genus Eimeria comprises obligate intracellular protozoan parasites belonging to the phylum Apicomplexa. Members of this genus cause enteric disease in a wide range of vertebrate hosts, including fish, reptiles, birds, and mammals. A total of 157 species of Eimeria that parasitize fish have been described; however, molecular information regarding ...

Impact of Endocrine Disruptors on Vitellogenin Concentrations in Wild Brown Trout (Salmo trutta trutta)

Bulletin of Environmental Contamination and Toxicology, 2020
The adverse effects of endocrine disruptors (EDs) on aquatic wildlife and human health represent a current issue of high public concern. Substantial knowledge of the level of estrogenic EDs in fish has accumulated from field surveys. For this purpose, a survey of wild brown trout (Salmo trutta trutta) was carried out to assess the incidence of EDs in ...

Interactions between ecto- and endoparasites in trout Salmo trutta

Veterinary Parasitology, 2002
Trout fry were experimentally infected with endoparasites (Anisakis sp.) and/or ectoparasites (Gyrodactylus derjavini). During the following 3 weeks the infection level of G. derjavini was significantly lowered in fish infected with live anisakids compared to fish injected with physiological saline, a corresponding amount of Anisakis protein sonicate ...

An homologous radioimmunoassay for brown trout (Salmo trutta) vitellogenin

Fish Physiology and Biochemistry, 1988
An homologous radioimmunoassay for brown trout vitellogenin (VTG) was developed. Intact VTG, isolated from juvenile brown trout by selective precipitation and anion exchange chromatography was labelled with Na(125)I, with 1,3,4,6-tetrachloro-3α,6α-diphenylglycoluril (Iodogen) as the oxidizing agent. Incorporation of Na(125)I into VTG was higher than 75%
