潮间带垒石蒙网养鲍技术研究

在潮间带进行垒石蒙网养鲍试验，４个岩礁区共设置１３６个石垛，放养壳长１．３￣３．０厘米的鲍５５．１万只，经１８个月养殖，共产商品鲍１９．２５４吨，平均亩产１３９７．８公斤，平均壳长６．８１厘米，成活率８９．６％，实现产值６９３．１４４万元，利润３５２．８１万元。该成果１９９６年被评为青岛市科技进步三等奖。

A STUDY ON FARMING ABALONE IN ROCK PILES COVERED WITH NET IN INTERTIDAL ZONE

An experiment was made on farming abalone (Haliotis discus haunai) with rock piles covered with net in the intertidal zone. In 4 rocky areas 136 rock piles were set up into which 553 thousand juvenile abalone with shell length of 1.4-3.0cm were released. After farming for 18 months the commercial abalones were harvested,altogether 19254kg, amounting to 1397.8 kg per mu on the average. The average size was 6.81cm in shell length and the survival was 89.6% on the average. The output price was 6.93144 million Yuan and the profit was 3.5281 million. The result,as appraised by experts, has set a record at home and reached the advanced level in the world. In 1996, it was awarded a third prize for Scientific and Technological Advancement by Qingdao City.
