| 中文摘要: |
| 自然低温条件下，研究了尼罗罗非鱼在粗盐及粗盐+碳酸氢钠（小苏打）作用下的耐寒能力及罗非鱼血液生化指标的变化。结果表明，粗盐组的罗非鱼相对保护率达90%；同一时间，各试验组罗非鱼血清中丙二醛、总蛋白、谷丙转氨酶、谷草转氨酶、甘油三酯和胆固醇差异均极显著；丙二醛和总蛋白水平及谷丙转氨酶和谷草转氨酶活力随温度的降低而升高，而甘油三酯和胆固醇水平则随温度升高而下降。结果表明，添加粗盐可提高罗非鱼的耐寒能力，罗非鱼血液生化指标随着温度的降低而改变，这与低温胁迫能导致罗非鱼昏迷及死亡有关。 |
| 英文摘要: |
| The cold-resistant capacity and serum biochemical parameters of tilapia in two drug groups (coarse salt, coarse salt +baking soda) were studied in the outdoor natural low-temperature condition. The results showed that the tilapia
relative protection ratio of coarse salt group reached 90%. At the same time, there were significant differences among the
serum MDA, TP, GPT, GOT, TG and TCH of tilapia. What’s more, the levels of MDA, TP, GPT and GOT increased with
the decrease of temperature, while the levels of TCH and TG decreased with the rising of temperature. The result indicated
that adding coarse salt could improve the cold-resistant capacity of tilapia, and this result gave explanation of the coma
and death of tilapia under low-temperature condition. |
