The effect of sudden temperature decrease on common carp under experimental conditions

Popis výsledku v původním jazyce

The objective of the present study was to evaluate stress caused by sudden temperature decrease on common carp under experimental conditions. Total of the 56 tested individuals of Cyprinus carpio were exposed to temperature 27.8 °C (T1). After 14 days of acclimatization, 28 individuals were moved to the water temperature 16.8 °C (T2); the rest was moved to the tank with the same temperature as the original one (T1). The water analysis together with the gaining of samples (n=7) for haematological and biochemical analysis, biometrical data and analysis of digestive tract activity was performed after 6, 12, 24 and 48 hours for both tested groups. In conclusion, the digestive process was slowed when fish were exposed to colder T2 water and the liquid constitution of digested feed in intestine was observed along with the visibly inflated intestine. Examined haematological and biochemical parameters were found to be decreased in T2. The lower ability of detoxification and excretion of endogenous ammonia was recorded for T2 at 6 and 12 hours in connection with water analysis. However, the concentration of ammonia in fish plasma was at comparable levels in the same time interval for both tested groups.
