中文摘要:
      在原位式和异位式的模式下,利用生物絮凝技术(Biofloc Technology, BFT)养殖吉富罗非鱼(GIFT Oreochromis niloticus)120 d。罗非鱼原位组(对照组)和异位组(实验组)初始体质量为(19.76±2.44)g和(21.01±1.23)g,初始养殖密度为(2.63±0.33)kg/m3和(2.80±0.17)kg/m3,实验结束实验鱼体质量分别达到(306.21±18.64)g和(338.49±19.35)g,养殖密度分别达到(33.29±0.83)kg/m3和(37.99±2.34)kg/m3。结果表明养殖前期两组中氨氮、亚硝氮均有明显积累,但中后期氨氮和亚硝氮浓度分别维持在3 mg/L和2 mg/L以下,两组硝氮浓度在整个实验过程中一直累积,实验组水质变化较对照组更稳定。两组实验鱼肌肉粗蛋白含量无显著差异。两组实验鱼胃蛋白酶活力同一时期没有显著差异,但是终末活性略低于初始活力;对照组鱼体肠组织中的胰蛋白酶活力在整个养殖期间都高于实验组。两组胃脂肪酶活力和肠脂肪酶活力同一时期没有显著差异。实验通过研究两种生物絮凝模式下吉富罗非鱼养殖效果,为生物絮凝技术在生产实践上的应用和完善提供参考依据。
英文摘要:
      In in-situ and non-situ modes, new GIFT tilapia (Oreochromis niloticus) was cultured with biofloc technology (BFT) for 120 d. Initial body mass of tilapia was (19.76±2.44) g, (21.01±1.23) g, and initial culture density was (2.63±0.33) kg/m3, (2.80±0.17) kg/m3. At the end of the experiment in situ group (control group) and non-situ group (treatment group),the weight of experimental fish were (306.21±18.64) g, (338.49±19.35) g. The culture density reached (33.29±0.83) kg/m3, (37.99±2.34) kg/m3. Ammonia nitrogen and nitrite nitrogen were accumulated in the early stage, but in the middle and late stages, the concentration of ammonia N was maintained below 3 mg/L and nitriter N maintained below at 2 mg/L. Nitrate nitrogen concentration has been accumulated in the whole experiment. The water quality of the treatment group was more stable than that of the control group. There was no significant difference in crude protein concentration between the two groups. There was no significant difference in stomach protease activity in each period, but the final activity was slightly lower than the initial activity. The trypsin activity in the intestinal tissues of the control group was higher than that in the treatment group during the whole breeding period. There was no significant difference in stomach lipase activity and intestinal lipase activity in the two groups.The experiment provides reference for the application and improvement of biofloc technology in production practice, through studying the effects of two kinds of bioflocculation modes on the production of new GIFT tilapia.
