Caspian brown trout (Salmo trutta caspius) is one of the economically valuable species in the Caspian Sea. Artificial propagation and production of larvae are the main problems in the early culture of this species. The purpose of this paper is to study the effect of reproductive performance of female broods on opposition reproduction efficiency in Caspian brown trout in the breeding season of 2...

in this study the genetic diversity of wild caspian trout (salmo trutta caspius) in the sardabroud and astara rivers was evaluated using d- loop region sequencing. for this purpose, 35 specimens of adult caspian brown trout were collected from these rivers in the mazandarn and gilan provinces in fall and winter 2011. approximately 3-5 g of soft and fresh fin tissue was isolated and fixed in eth...

The bacterium Pseudomonas angui1liseptica Wakabayashi & Egusa, originally described as a pathogen of eel in Japan, was isolated from diseased Atlantic salmon Salmo salar, sea trout Salmo trutta, rainbow trout Salmo gairdneri, and whitefish Coregonus sp. in Finland. Biochemical tests showed that the Finnish isolates are similar to the Japanese strains except for the Tween 80 reaction. Serologica...

in this study, three different age groups of male broodstocks (4, 5 and 6 years respectively) were used to fertilize eggs obtained from nine females. the results showed that 6 year old males had maximum body weight (1766 g), total length (56.3 cm) and sperm volume (31.83 ml). results did not show significant difference in spermatocrit and spermatozoa concentration among age groups (p>0.05). our...

Atlantic salmon Salmo salar, brown trout Salmo trutta (including the anadromous form, sea trout) and Arctic charr Salvelinus alpinus (including anadromous fish) provide important commercial and sports fisheries in Western Europe. As water temperature increases as a result of climate change, quantitative information on the thermal requirements of these three species is essential so that potentia...

The genetic structure and the phylogenetic relationships among five Balkan populations of trout Salmo trutta that have been classified earlier into five different taxa were studied, using microsatellite and mitochondrial DNA (mtDNA) analyses. The pattern of population differentiation observed at microsatellites differed to that depicted by mtDNA variation, yet both methods indicated a very stro...

High-density linkage maps are valuable tools for conservation and eco-evolutionary issues. In salmonids, a complex rediploidization process consecutive to an ancient whole genome duplication event makes linkage maps of prime importance for investigating the evolutionary history of chromosome rearrangements. Here, we developed a high-density consensus linkage map for the brown trout (Salmo trutt...
