摘要
分别在拥挤胁迫后第0、7、15、30d对鲫鱼(Carassius auratus)肝脏抗坏血酸含量和脏器系数进行了测定。结果显示,试验前鲫鱼肝脏中抗坏血酸浓度较高,平均为0.031mg/mL,拥挤胁迫后抗坏血酸含量呈下降趋势,至第30d降到最低点,为0.009mg/mL。拥挤胁迫7d后,鲫鱼肝脏系数变化不显著(p>0.05),脾脏系数显著降低(p<0.05),而高密度组又显著低于低密度组。胁迫30d后,高、中密度组的肝脏系数均显著高于低密度组(P<0.05),而两密度组的脾脏系数均显著低于低密度组(P<0.05)。
The Content of Ascorbic Acid and the Organ Coefficients in Carassius Auratus＇s Liver were Detected 0, 7, 15 and 30 Days Later than Crowding Stress was Conducted, Respectively. The Results showed that the Concentration of Ascorbic Acid in Carassius Auratus Liver Prior to Crowding Stress Test was in Higher Level with an Average Amount of 0.031mg/mL, While After Crowding Stress Test, the Content of the Ascorhic Acid in Carassius Auratus Liver Exhibited Decreasing Tendency and after 30 Days, the Minimum Value was 0.009 mg/mL. Seven Days after Crowding Stress, the Change in Carassius Auratus Liver Coefficient was not Significant （P〉0.05） while the Spleen Index Decreased Observably （P〈0.05）, Meantime, the Spleen Index in High Density Group was Significantly Inferior to that in Low Density ones. Thirty Days after Crowding Stress, the Liver Index in High and Middle Density Group were Noticeably Higher than those of Low Density Group （P〈0.05） while the Spleen Index in both High and Middle Density Group were Significantly Lower than those of the Low Density Group （P〈0.05）.
