| 摘要: |
| 比较了自然沙、棕色陶粒、白色陶粒、70%棕色陶粒+30%贝壳砂、贝壳砂等5 种底质材料及空白对照组(无底质), 对体质量为0.193 g±0.03 g 的方斑东风螺生长、存活、摄食以及培育过程中水质的影响。结果表明, 白色陶粒组的存活率为80%, 显著低于其他各组(P<0.05); 棕色陶粒组的体质量特定生长率最高(4.31%/d), 且显著优于白色陶粒组和对照组(P<0.05); 棕色陶粒处理组方斑东风螺的饵料转化效率显著高于白色陶粒组和空白对照组; 水质中总氨氮、亚硝酸氮和COD 均呈上升趋势, 各组之间差异不显著。 |

| Effect of different bottom substrate materials on the growth and survival of spotted babylon (Babylonia areolata) |

| Abstract: |
| The effects of five kinds of bottom materials on the growth, survival, and Total ammonia nitrogen (TAN), nitrite and COD in breeding of Babylonia areolata (0.193±0.03 g) were investigated. Results showed that the survival rate of white ceramic group was 80%, which was significantly lower than that of other groups (P<0.05). Weight specific growth rate under brown ceramic group was the highest, which was 4.31%/d, which was significantly better than white ceramic group and control group (P<0.05). The feed conversion efficiency of brown ceramists group was higher than that of no bottom and white ceramic groups (P<0.05). TAN, nitrite and COD increased during experiment, but the differences were not obvious between the groups. Using brown ceramist instead of natural sand as bottom quality is suggested to improve the growth and survival of Babylonia areolata. |
