Changes in Chemical Compositions during Development of Rainbow Trout Eggs

Changes in blood pressure in the rainbow trout during hypoxia.

The influence of hypoxia upon the heart rate and the rate and amplitude of breathing in the tench has been reported by Randall & Shelton (1963). Satchell (1961) demonstrated that dogfish respond to anoxia by decreasing heart rate, temporarily increasing dorsal aortic blood pressure and increasing the mean and pulse pressure in the ventral aorta. These fish were restrained and anaesthetized. In ...

Uptake of 106Ru by eggs and fry of rainbow trout.

The experimental studies on uptake and accumulation of 106Ru by artificially fertilized eggs, advanced fry and fingerlings of rainbow trout have been conducted. The accumulation in the egg previously treated with drugs for control of bacterial growth on the egg was more rapid and higher than that in non-treated egg. The major part of 106Ru in the egg was associated with the egg capsule on hatch...

IGF-I binding in primary culture of muscle cells of rainbow trout: changes during in vitro development.

To characterize and study the variations of IGF-I binding during the development of trout muscle cells, in vitro experiments were conducted using myocyte cultures, and IGF-I binding assays were performed in three stages of cell development: mononuclear cells (day 1), small myotubes (day 4), and large myotubes (day 10). Binding experiments were done by incubating cells with IGF-I for 12 h at 4 d...

Fungal contamination in rainbow trout eggs in Kermanshah province propagations with emphasis on Saprolegniaceae

  Fungal infection in the eggs of freshwater fish is well known as a problematic disease. The aim of the present study was to isolate and identify parasitic and saprophytic fungi from affected eggs of rainbow trout at two fish hatchery in Kermanshah province. The sample were inoculated in culture media (SDA,CMA,GPA and stilled water with cotton seed culture) at room temperature (18-24 ° C).17 s...
