The main objective of this study was to evaluate alternate vegetable proteins as a replacement for fish meal in diets of Labeo rohita and Ctenopharyngodon idella and use the findings to formulate a cost effective diet for freshwater fish species. Fish of an average weight of (L. rohita 1.91±0.05; C. idella 19.57±0.09 g) was stocked in four earthen fish ponds. The feed was prepared from five dif...
the studies of parasitology was performed on freshwater in farm ponds in isfahan province during the years of 2006- 2008 and in total were fished 150 fish from farm ponds of freshwater fish and dual purpose of agriculture of three regions in isfahan. the fish were 65 cyprinus carpio, 40 hypophthalmichthys molitrix and 45 ctenopharyngodon idella. the samples were taken to laboratory alive and af...
The grass carp (Ctenopharyngodon idella) is a herbivorous, freshwater fish species of the family Cyprinidae, and the only species of the genus Ctenopharyngodon. Neoplasms in fishes are generally less aggressive than neoplasms in mammals and are most commonly discrete, focal and benign neoplasms. A 3-year-old grass carp with a big mass on the vertebrae was referred to the clinic. According to the...
The relationship of gonad weight and liver weight with body weight of six fish species viz; Catla catla, Labeo rohita, Cirrhina mrigala, Hypophthlamichthys molitrix, Ctenopharyngodon idella and Cyprinus carpio under the influence of artificial feed, broiler manure, buffalo manure, N:P:K (25:25:0) and a control pond were examined after a rearing period of one year. The positive relationship betw...
The state of knowledge of grass carp ( Ctenopharyngodon idella Val.) effects on water bodies are summarized based on a review of selected literature and my own experience from South Bohemian ponds. The subjects considered include aquatic plant control using grass carp, fish age and stocking densities, and direct and indirect consequences of its introduction to water bodies including impacts on ...
Motile aeromonads isolated from the intestines of farm-raised freshwater fish such as Catla catla, Labeo rohita and Ctenopharyngodon idella have been characterized to species level. Morphological and physiological grouping revealed 61% Aeromonas hydrophila, 30% Aeromonas caviae, 7% Aeromonas sobria and 2% which remained unidentified. Hemolytic activity was detected mostly in A. hydrophila, whil...
The acute toxicity of Nuvan to the grass carp Ctenopharyngodon idella was determined using static and continuous flow through system for 24, 48, 72 and 96 hr. The median lethal concentration (LC50) values were 13.1, 10.9, 9.8 and 6.5 mg l(-1) respectively in static system and 10.7, 9.5, 8.0 and 7.5 mg l(-1) respectively in continuous flow through system. A reduction in oxygen consumption is obs...
