| 中文摘要: |
| 2011年4~11月比较了两种养殖密度（低密度和高密度）下鲫鱼的生长率和组织中超氧化物歧化酶（SOD）、碱性磷酸酶（AKP）、酸性磷酸酶（ACP）活性的差异。结果显示，低密度塘鲫鱼生长和免疫酶活性在4月7日低于高密度塘，而后明显高于高密度塘；两种养殖密度下，7~9月为鲫鱼的最佳生长时期。结果表明，放养密度过低会对鲫鱼早期生长和免疫力造成负面影响，放养密度过高则不利于鲫鱼后期生长和免疫力的提高。 |
| 英文摘要: |
| Growth and tissue superoxide dismutase (SOD), alkaline phosphatase (AKP), acid phosphatase (ACP) activities of Crucian carp (Carassius auratus) under two densities were compared from April to November in 2011. The results showed that growth and immune enzyme activities of Crucian carp in low density pond were lower than those in high density pond on April 7th, after higher than those in high density pond. The optimal growth period for Crucian carp was from July to Septemper. The results indicated that low breeding density would affect growth and immunity at initial breeding stage, while high breeding density resulted in bad growth and low immunity in the later breeding period. |
