潮间带垒石蒙网养鲍技术研究

1994年4月～1995年10月，在4个岩礁区共设置136个石垛，放养壳长1．3～3．0cm鲍苗55．1万只，进行潮间带垒石蒙网养鲍试验。对场址选择、放养密度、规格、投饵方法等进行了研究。结果：产商品鲍19．254t，平均亩产1397．8kg，平均壳长6．81cm，平均个体重39g，成活率89．6％，实现产值693.144万元、利润352.81万元。专家鉴定认为，养殖方式为国内首创，技术水平属世界先进。

Studies on Technique for Farming Abalone with Piling Stones Covered with Net in the Intertidal Zone

An experiment was made on farming abalone(Haliotis discus hannai)with piling stones covered with net in the intertidal zone. From April of 1994 to October of 1995 136 stone piles were set up in 4 reef areas into which 553 thousand juvenile abalones with the shell length of 1. 4-3. 0cm were released. In the farming period some techniques such as the choice of ground for culture, releasing density and feeding method were also studied. After farming 18 months the commercial abalones were harvested altogether 19 254kg, per mu yield 1 397. 8 kg on average.The average size was 6. 81cm in shell length and the survival rate was 89. 6 % on average. The output price was 6. 931 44 million yuan and the profit was 3. 528 1 million yuan. The result, appraised by experts, was set a record at home and met the advanced level in the world.
