摘　　要：本文报道了从1993年5月～1994年10月开展潮间带网箱养鲍的试验。在选好的岩礁区筑坝建池，防止落潮后网箱干露，利于鲍鱼度夏和越冬；利用网箱养鲍，便于管理，并可防止鲍鱼外逃及敌害生物侵入；苗种壳高2厘米以上，以提高其成活中；放养密度：壳高4厘米以前，每平方米200～300只，壳高4厘米以后，每平方米50～100只，可利于鲍鱼生长；饵料以海带、裙带菜为主，水温低于8℃时，很少投饵，水温8～15℃，每10天投饵一次，投饵量为鲍体重的10％，水温15～24℃，每3天投饵一次，投饵量为鲍体重的20～30％，水温高于24℃，每3天投饵一次，投饵量为鲍体重的10％；每5～7天清池一次，及时清除敌害及残饵，以保持水质清新和水环境稳定。18个月养殖，共产鲍4305公斤，平均壳高6．1厘米，成活率为76．5％。A study on abalone cage culture in May, 1993 to Nov., 1994 is reported in this paper. Building a pond in a proper rocky area to avoid the axposure of cage during low tidal period is a good way for abalone to live through the winter and summerThe cage culture technique is convenient for management and for avoiding the escape of ablone as well as the intrusion of harmful organisms. The shell height of spat should be oYer 2cm in order to increase tlie survival rate. The culturing density may be 200-300 inds./m2 when the shell height is less than 4cm and 50 -100 inds./m2 when the shell height is more than 4cm. The main feeds for abalone are Laminaria and Undaria and the regime is: a1most no feedinZ when thetemperature is lower than 8℃ , once per 10 days feeding with 10% of abalone weight in 5-15℃ , once per 3 days feeding xvith 20-30% of abalone weight in 15 -24℃ , and once per 3 days feeding with 10% of abalone weight if the temperature is higher than 24℃. The pond should be cleaned every 5-7 days in order to eliminate harmful organisms and residual feed to keep good water quality. After 18 months the total production was 4, 305kg, the average shell height being 6.1 cm with 76.5% of surviyal rate.
