摘要
利用人工构建的藻丛刷(Algal Turf Scrubber,ATS)系统处理条纹斑竹鲨养殖用水,并对水中NO3--N、NO2--N、NH4+-N和PO43--P等水质指标进行监测,以确定藻丛刷系统对观赏鱼养殖用水水质的净化效果。试验为期60d,试验期间不换水。结果表明,整个试验期间,水中NO3--N含量维持在5.64-9.87mg/L范围内,NO2--N含量维持在0.03-0.07mg/L范围内,NH4+-N含量维持在0.03-0.07mg/L范围内,PO43--P含量维持在1.33-1.78mg/L范围内。由此可见,在合适的养殖密度和适当的投饵条件下,藻丛刷系统能够有效净化鲨鱼养殖用水水质,使其在不换水情况下维持在稳定范围内。
In order to investigate effects of algal turf scrubber(ATS)on cultivated water purification of ornamental fish,artificial ATS was used to purify cultivated water of Chiloscyllium plagiosum and water quality indicators,including NO3%--N,NO2--N,NH4^+-N and po4^3--P, were measured.The experiment lasted for 60d and water was not renewed.The results showed that contents of NO3^--N, NO2^--N,NH4^+-N and PO43^--P were kept in the range of 5.64-9.87mg/L,0.03 - 0.07mg/L,0.03 -0.07mg/L and 1.33-1.78mg/L respectively during the whole experiment.It was indicated that ATS could purify cultivated water of Chiloscyllium plagiosum effectively and maintain stabilization of water quality when shark were cultured with appropriate density and feeding dose.
