多瑙河六须鲶为多瑙河流域重要的经济鱼类,该鱼适温广、生长快、个体大、肉味鲜美,因而,引起了人们的关注。1992年我所从湖北省水产研究所引进苗种进行饲养观察,发现该苗种易感染小瓜虫病,在使用0.1-0.2ppm硝酸亚汞治疗时,苗种产生敏感性。现将我们的观察和治疗结果介绍如下: 一、引种情况 1992年4月24日苗种从湖北空运至福州、共203尾,个体平均全长5.70cm,平均体长5.20cm,体重1.70g,运输成活率100%。苗种到达后直接放入本所面积为12m~2的3#水泥池中培育,培苗用水系半个月前蓄好的暴气自来水,水深为90cm,下苗第二天就开始每天用90目浮
Danube six catfish as the Danube watershed important economic fish, the fish wide temperature, rapid growth, individual large, delicious meat, which attracted people’s attention. In 1992, I introduced seedlings from Hubei Provincial Institute of Fisheries to observe the feeding and found that the seedlings were susceptible to Aspleniumiasis. When using 0.1-0.2ppm mercuric nitrate treatment, the seedlings were sensitive. Now the results of our observation and treatment are introduced as follows: I. Introduction The April 24, 1992 seedlings from Hubei to Fuzhou by air, a total of 203 individuals average length of 5.70cm, average body length 5.20cm, weight 1.70g, Transport survival rate of 100%. After the arrival of seedlings directly into the area of 12m ~ 2 3 # cement pool nurturing seedlings water system half a month ago, buoyed by storm water, water depth of 90cm, the next day after the seedlings began to use every day 90 mesh float
