海泥附着基的青蛤工厂化育苗试验

Experiment in industrial artificial breeding of Cyclina sinensis used sea mud as adherings substance

摘要: 以海泥为附着基的青蛤工厂化育苗试验于2004年6月28日至10月12日在江苏灌东盐场的育苗场进行。第一批试验的育苗水体为87.5 m3，平均单位育苗量为96.7 gm-3（66.8104 indm-3）；第二批试验的育苗水体为70.0 m3，平均单位育苗量为108.8 gm-3（40.5104 indm-3）；第3批试验的育苗水体为105.0 m3，平均单位育苗量为96.0 gm-3（49.9104 indm-3）。在3批262.5 m3育苗总水体中，共培育出单水管期稚贝104 600 g（55 665.1104 ind），单位水体育苗量的总平均数为99.6 gm-3（3批个体数53.0104 indm-3）。附苗率达到86%～88%。

Abstract: This experiment was conducted by using sea mud as adhering substance in Hatchery of Guandong Salt Farm, Jiangsu from Jun.28 to Oct.12, 2004. Average output is 96.7gm-3（66.8104 indm-3）in volume of 87.5 m3 for the first group The second group is 108.8 gm-3 (40.5104 indm3) in volume of 70.0 m3. The third group is 96.0 gm-3 (49.9104 indm-3) in volume of 105.0 m3. Output of juveniles in period of single water nozzle was 104 600 g (55 665.1104 ind) of all of three groups in 262.5 m3. The average yield is 99.6 gm-3(53.0104 indm-3) and percentage of adhering reached 86%～88%.
