Nitrite Intoxication of Common Carp (Cyprinus carpio L.) at Different Water Temperatures

Popis výsledku v původním jazyce

Common carp (Cyprinus carpio L.) were exposed to nitrite (1.45 mmol#l-1 NO2-) for 48 hours at 14 °C and 20 °C, in order to investigate the mechanism of nitrite poisoning at different water temperatures. The effect of nitrite exposure on fish at differenttemperatures was assessed on selected haematological and biochemical parameters of the blood. Moreover, nitrite accumulation in the blood, liver and muscle was measured. Nitrite exposure produced high levels of methaemoglobin (88.2 3.3 % and 92.9 6.1 %)at both water temperatures compared with controls (0.3 0.6 % and 2.6 3.0 %). High fish mortality occurred in experimental groups (30 % and 51 %) compared with controls (0 %). Nitrite exposure also resulted in an accumulation of nitrite in the fish body.The highest nitrite levels developed in the blood plasma, followed by the liver and muscle, respectively. Carp concentrated nitrite in the blood plasma and tissues to markedly higher levels at higher temperature (20 °C). The plasma nitri
