Induction of triploidy in grass carp Ctenopharyngodon idella Valenciennes, 1844: Comparison of cold & heat shocks
Triploidy in grass carp, Ctenopharyngodon idella Valenciennes, 1844, was induced on fertilized eggs to compare cold and heat shocks. Two simplified methods explained for verification of triploidy in grass carp. The cold shock (7 ?C) was given in three treatments for 30 min starting 2.0, 2.5 and 4.0 min after fertilization. In cold shock, the start point (2.0 min after fertilization) showed th...

متن کاملMorphometric and molecular characterization of Dactylogyrus lamellatus isolated from farmed Grass carp, Ctenopharyngodon idella (Valenciennes, 1844), in Guilan province, Iran
Grass carp is an herbivorous species, which is actually popular in Iran. Monogenean parasites, particularly members of the family Dactylogyridae, have been one of the main causes of mortalities in Iranian fish farms and therefore they have been subject of many studies in Iran. The main aim of the present study was to describe morphological and molecular characteristics of monogenean parasites r...
متن کاملFood preference and growth of grass carp, Ctenopharyngodon idella (Cuvier and Valenciennes, 1844) fed some aquatic and terrestrial plants
The present study was carried out to examine 6 plants including aquatic and terrestrial plants on food preference and growth of grass carp. 7 experimental treatments with three replicates were considered. The experimental treatments were ponds containing T1: M. spicatum, T2: C. demersum, T3: A. filiculoides, T4: L. minor, T5: C. dactylon, T6: M. sativa and T7: M. Spicatum + C. demersum + A. fil...
متن کاملEvaluation the performance of anaesthetic effects of Tobacco and Ketamine on Grass carp, Ctenopharyngodon idella (Valenciennes, 1844)
The present study aimed to determine the optimal concentration of three anaesthetics, name MS222, ketamine, and tobacco extract, in grass carp juveniles (107.78±22.11 g body weight and 226.74±13.06 mm total body length). Treatments were as follows: 100 mg L-1 of MS222 (control group), 5.5, 8, 11, 18.5, and 22 mg L-1 of ketamine, and 10, 13.33, 20, 26.27, and 40 mg L-1 of tobacco extract. In add...
