摘要:
藻类是对虾养殖系统中最主要的初级生产力,不仅为养殖对象提供氧气、天然饵料等,还能吸收氮磷减少水体富营养化,但是不同藻类对氮磷的吸收存在较大差异。因此为有效了解不同微藻对南美白对虾养殖尾水的去除作用,通过室内微藻培养试验,分析了8株微藻在南美白对虾养殖尾水的生长性能及不同时间内其对氮磷的去除效果。结果表明:8株藻均能在南美白对虾养殖尾水中生长,其中铜绿微囊藻、衣藻和蛋白核小球藻生长较好,平均相对生长速率分别为0.3093、0.2469和0.2155。8种藻类对TN、TP的去除效果差异较大,其中铜绿微囊藻、衣藻和蛋白核小球藻对TN去除效果较好,培养结束时去除率分别达到74%、69%和60%;铜绿微囊藻和衣藻均具有较好的TP去除效果,去除率达60%以上,其次为蛋白核小球藻。不同藻类对不同形态氮的吸收存在较大差异,铜绿微囊藻和衣藻具有较好的硝态氮去除效果,去除率达到70%左右;衣藻对氨氮具有较快且持久的去除率,去除率高达100%,铜绿微囊藻和蛋白核小球藻稍慢,而斜生栅藻、针杆藻和舟形藻最慢,在培养16天后,去除率均达到90%以上;隐藻和蛋白核小球藻对亚硝态氮具有较好的去除效果,培养至第8天时即达到80%去除率,且隐藻去除效果较持久。研究结果可以为南美白对虾养殖过程中藻相的定向培育和利用微藻去除对虾养殖尾水污染物提供科学参考。
Abstract:
Objectives: Microalgae are the most important primary productive forces in shrimp aquaculture systems. They not only provide oxygen and natural feed for aquaculture objects, but also absorb nitrogen and phosphorus to reduce water eutrophication. However, They are great differences in nitrogen and phosphorus absorption among different microalgae.Methods: In order to maintain sustainable development of shrimp aquaculture, the growth performances of 8 microalgae strains in Penaeusvannamei sewage, and nitrogen and phosphorus removal rate were investigated under lab condition .Results: The results indicated that 8 microalgae strains could reduce the nitrogen and phosphorus content in Penaeusvannamei sewage to some extent . Microcystisaeruginosa, Chlamydomonassp. and Chlorellapyrenoidosa growed very well and the average growth rate were 0.3093, 0.2469 and 0.2155 respectively. While there were significant differences in removal efficiency among the different strains. The removal rate s of M.aeruginosa, Chlamydomonassp. and C.pyrenoidosa on TN were 74%, 69% and 60%, respectively at the end of experiment which was better than others. M.aeruginosa and Chlamydomonas?sp. had better TP removal efficiency than other microalgae strains , and the removal rate was more than 60%, and the second was C. pyrenoidosa. Different kinds of microalgae strains have different absorption of different morphological nitrogen. The M.aeruginosa and Chlamydomonas?sp. had the highest nitrate nitrogen removal rate ( about 70%). Chlamydomonassp. had a fast and persistent removal rate of ammonia nitrogen, and the removal rate was as high as 100%. M.?aeruginosa and C. pyrenoidosa were a little slower, and Scenedesmusobliquus, Synedrasp. and N.graciloides were the slowest. After 16 days, the removal rate reached more than 90%. Cryptomonasobovate and C.pyrenoidosa displayed the best removal of nitrite nitrogen, and the removal rate reached 80% at 8th day, and the effect of C.obovata was more persistent. Conclusions: The results can provide scientific reference for the orientation and use of microalgae to remove the pollutants of tail water in shrimp aquaculture.
