Recovery of rainbow trout (Oncorhynchus mykiss) after subchronic nitrite exposure

Popis výsledku v původním jazyce

The aim of the study was to assess the effect of elevated nitrite concentration on the haematological and biochemical profile of blood of rainbow trout and to evaluate the ability of fish to recover under varying conditions. Fish (n = 72) were exposed for 14 days to elevated nitrite concentration (1 mg.l(-1)). Thereafter the exposed fish were divided into four groups and monitored for 7 days in the following conditions: water containing 1 mg.l(-1) NO2 (group E), water containing 1 mg.l(-1) NO2- + 100 mg.l(-1) Cl- (group R1), nitrite-free water with 100 mg.l(-1) Cl- (group R2), or nitrite- and chloride-free water (group R3). Nitrite exposure was associated with a significant increase (P { 0.01) in methaemoglobin, mean corpuscular haemoglobin and plasmanitrite concentration. During the subsequent 7 days these indices reached the control values in all recovery groups (R1 R3). Significant decrease (P { 0.01) in haematocrit and mean corpuscular volume was recorded during nitrite exposure o
