Effects of pH on sodium uptake in Norwegian brown trout (Salmo trutta) from an acid river.

Acclimation to an acid medium in the brown trout Salmo trutta.

Data are presented which demonstrate acclimation of brown trout (Salmo trutta) to an acid medium. Sodium fluxes, transepithelial gill potentials and plasma electrolyte concentrations were measured in brown trout exposed to an acid medium of pH 6.0 for a period of 6 weeks. Sodium loss rates in acid exposed fish are reduced compared to normal fish, and sodium uptake in insensitive to external pH ...

شجره شناسی ماهی قزل‌آلای خال‌قرمز (Salmo trutta L. 1758) رودخانه جاجرود با استفاده از توالی ناحیه D-Loop

In this study phylogenetic relationship of the Jajrud River Brown trout Salmo trutta L. 1758 in the Namak Lake basin was analyzed using complete D-Loop sequence of the mitochondrial genome, compared to other Iranian populations of the species. The results clarified that Jajrud brown trout, similar to other Iranian brown trout populations belongs to the Danube phylogenetic lineage. The observed ...

The effects of calcium on sodium fluxes in the brown trout, Salmo trutta, in neutral and acid water.

Blood parameters of Caspian brown trout (Salmo trutta caspius) fingerlings affected by dietary L-ascorbyl-2-polyphosphate

This study was aimed to evaluate the effect of L-ascorbyl-2-polyphosphate as a dietary ascorbic acid source on blood parameters of Caspian brown trout (Salmo trutta caspius), including red blood cell (RBC) count, white blood cell (WBC) and WBC differential. A total number of 600 Caspian brown trout (9.6±0.6 g) fingerlings were randomly distributed in triplicates among five treatments each conta...

The effects of extender type, freezing and thawing rates on fertility of the cryopreserved semen of the Caspian brown trout (Salmo trutta caspius )

Cryopreservation of semen from the Caspian brown trout (Salmo trutta caspius) and effects of extender type, freezing and thawing rates on fertilization ability were studied. After assessment of semen quality, one part of semen was diluted with three parts of different extender and decanted into 0.5ml straws. Freezing was carried out at two freezing levels, 1.5cm and 2cm above surface of liquid ...
