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 g · m^-3(66.8×10⁴ ind · m^-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 g · m^-3(40.5×10⁴ ind · m^-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 g · m^-3(49.9×10⁴ ind · m^-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(55 665.1×10⁴ ind)，单位水体育苗量的总平均数为99.6 g · m^-3(3批个体数53.0×10⁴ ind · m^-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 96.7g · m^-3(66.8×10⁴ ind · m^-3)in volume of 87.5 m³ for the first group. The second group is 108.8 g · m^-3(40.5×10⁴ ind · m³)in volume of 70.0 m³. The third group is 96.0 g · m^-3(49.9×10⁴ ind · m^-3) in volume of 105.0 m³. Output of juveniles in period of single water nozzle was 104 600 g(55 665.1×10⁴ ind) of all of three groups in 262.5 m³. The average yield is 99.6 g · m^-3(53.0×10⁴ ind · m^-3)and percentage of adhering reached 86%~88%。
