【摘要】 为寻求适应我国北方沿海的优良养殖品种,我们于1992年和1994年先后两批从英国引进全长6～9cm的大菱鲆苗,在青岛和威海两地进行驯养和生长观察,1992年8月至1996年8月的试验结果表明:大菱鲆在青岛和威海的自然水温条件下,均表现出良好的生长趋势,1龄鱼体长增长快,2龄鱼体重增长加速.尤其在威海崮山点,年平均增长速度可达850g.最大个体达1kg以上.青岛点夏季水温(26℃以上)高于威海1.5～2.0℃左右,且持续约2个月,对1龄鱼的成活率尚无多大影响,而对2龄鱼则容易构成威胁,但只要加强管理或稍加降温措施即可安全度夏.此外,对养殖期间的生态和病害进行了观察;对养殖前景亦进行了评估.更多还原

【Abstract】 This paper report that the experiment on introduction and domestication of two batches turbot which introduced from British in 1992 and 1994 respectively, with total length about 6cm to 9cm. The two batches fry were cultured in Qingdao and Weihai. The experimental result show that turbot which grew in the two sites both have a good growth trend under the condition of natural water temperature. One-year-old turbot have a fast growth speed on body length, and two-year-old turbot have a fast growth speed on body weight. The total length of one-year-old turbot can reach to 24-34cm, the body weight can reach to 300-1000g. The average growth speed is 850g/year, the fastest speed can reach to 1kg/year. The water temperature is up to 26°C in summer of Qingdao which is higher 1. 5-2°C than Weihai. This temperature has no bad effect on one-year-old turbot survival, but it can menace the survival of two-year-old turbot. Furthermore, we also did some observe on the turbot’s diseases , such as Trichodinosis and Annelida and on the treatment.更多还原
