Five isonitrogenous diets (approximately 33% crude protein) were fed to the brood female carp, Catla catla (weighing 3.0 to 5.5 kg), for a period of 93 days in order to observe their breeding performance in earthen ponds. Diet-I (control) contained only basic ingredients like rice bran, ground-nut oil cake, roasted soybean meal, fish meal and mineral mixture; diet-II contained added vitamins; d...

Objective: The present report describes the green synthesis of Zinc oxide nanoparticles (ZnO NPs) using Argemone maxicana leaf extract by an eco-friendly approach. Also, the in-vitro cytotoxicity of prepared ZnO NPs against the cardiac cell lines of Sahul India Catla catla fish (SICH) was studied. Methods: ZnO NPs were prepared by using Argemone maxicana leaf extract as reducing and stabilizing...

Summer season with 30C is taken as control, where as rainy season with 20C is taken as cold stress and winter season with 15C is taken as cold adaptation. During summer season (control) The Acetyl Choline Esterase Increases, fats decreases and fatty acids increases. The fatty acids are utilized by the fish for its strenuous activity during summer. During Rainy, season due to cold stress the fat...

myxosporean taxonomy which is traditionally based on the morphology of the myxospore stage, is in a state of flux given new insights provided by the expanding dataset of dna sequences. to date, more than 40 species of thelohanellus from india have been described according to morphometric characteristics. nevertheless, molecular data on these histozoic myxosporean parasites of freshwater fish ar...

the experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile catla catla in the laboratory for 90 days. fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8l:16d), 16 hours light: 8 hours dark (16l:8d), continuous light (24l:0d) and co...

The two vital respiratory parameters namely Oxygen consumption of the whole fish and Opercular activity in Indian Major Carp was investigated during thermal-stress Thermal-adaptation. major carp Catla catla subjected to Slow temperature change from 22 ⁰c 32⁰c (heat-adaptation) (cold -adaptation) at rate 1⁰c ̷ 60 hours showed a gradual stepping-up oxygen opercular heat-adaptation stepping-down ca...
