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 ...
متن کاملAcclimation 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 ...
متن کاملThe Effect of Calcium Concentration of Water on Chloride Cell Density in Gill of Brown Trout (Salmo trutta L.) Larvae
The effects of the calcium concentration on chloride cell (mitochondria-rich cell) density in the gills of brown trout (Salmo trutta L.) larvae were studied. For this purpose, animals were divided into 3 groups 2 weeks after hatching and each groups was exposed to different calcium concentrations of water for two weeks. The results showed that the number of chloride cells in gill arch epithelia...
متن کاملThe effects of hypophysectomy, prolactin therapy and environmental calcium on electrolyte balance of the brown trout Salmo trutta, L.
Adaptation of the brown trout to fresh water containing increasing concentrations of calcium resulted in a decrease in plasma electrolyte level and total electrolyte excretion. The electrolyte excretion rate was higher at the beginning than at the end of the urine collection periods. Hypophysectomized fish had a lower plasma electrolyte concentration than the controls. This deficiency was parti...
متن کاملBlood 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...
