【摘要】 在锅炉加温的条件下，采用“Ｕ”形管、排污板，从底层排污的方式保持水质良好；试验水温３１．５℃略高于传统的２５～３０℃饲料上采用幼鳗料加味处理；疾病防治上采用了不会产生抗药性的广谱杀菌剂，采取定期较高浓度遍洒的办法，严格控制抗生素的使用种类、剂量、范围和时间。２．１４万只，平均体重１７．４５ｇ的稚鳖，经２１０ｄ培育，平均体重达到２０８．５ｇ，日均增重０．８２７ｇ，饵料系数３．３５，成活率９１．６％。更多还原

【Abstract】 Under the condition of warming up by use of boiler,water quality was main-tained by getting rid of sewage from the sewage scavenging plate bottom through“U shape”tubes。The experimental water temperature was 31.5℃,a little higher than tradi-tional 25～30℃ The bait was young eel to which other ingredients were added. The dis-eases were prevented and cured by periodical spray of comprehensive germicides whichcould’t make microorganisms to become drug fast.When antibotics were used, the var-ities,amount,scope and time were under strick control.After young Amyda sinesis grew2l0 days,their average body weight increased to 208.5 grams from l7.45 grams,increas-ing by an average of 0.827 gram a day, The bait coeffectient was 3.35.The survivalratewas 9l.6%.更多还原
