英文摘要:
      A total of 85 interspecific hybrid F2 (Cyprinus carpiovar. wuyuanensis×Cyprinus pellegrini pellegrini) were cooled to specific temperatures and held at those temperatures over a maximum of 4 days in a water recycled and temperature controlled aquarium inside. As a result, the blood homeostasis of experimental fish changed violently as acute temperature changed from 16 ℃ to 10 ℃ and 4 ℃ at a rate of 1 ℃·h-1 according to the data we collected. Whole blood pH, also called extracellular pH (pHe) were very sensitive to temperature changes, where the re was a significant difference between 10 ℃ (7.41) and 16 ℃ (7.17) (P <0.01), compared to other values of hematology and serum chemistry. When the water temperature was continually decreased to an extreme temperature of 4℃, the content of Na+ of serum decreased remarkably in comparison with that of 10 ℃ and 16 ℃, which was 85.2 mmol·L-1, 113.3 mmol·L-1 and 118.7 mmol·L-1, respectively. The values of hematology and serum chemistry also altered in gentle temperature changes of (10±2) ℃ and (4±2) ℃. Most values of serum chemistry and pH changed significantly, whereas the values of blood plasma changed slightly. pH was up slowly in 4 days at (10±2) ℃ and down slowly in 3 days at (4±2) ℃. A variety of values of serum chemistry changed remarkably both at (10±2) ℃ and (10±2) ℃, but the values of TP, TG and ALB only changed significantly at (4±2) ℃. These results distinguished at least two mechanisms involved in cold induced stress in hybrid F2. Cold induced pH changes resulted in other values altered. What's more, pH correlated negatively with water temperature above 10 ℃, and the content of Na+. We also found that gentle te mperature changes will be physiologically compensated for on day one at (10±2) ℃ and on day 2 at (4±2) ℃ in hybrid F2.
