采用海水贝、鱼、芦苇生态养殖模式,维护系统生态平衡。通过检测系统内叶绿素a含量的变化,以监测系统中各池贝类规格、数量与叶绿素a的变化关系。结果表明,系统运行过程中,叶绿素a含量从上游向下游逐渐降低;成贝对叶绿素a的日消耗量为0.3μg/L·kg-1以上,种苗的日消耗量为0.2μg/L·kg-1左右;系统消耗叶绿素a的总量大于单细胞藻类自繁产生的叶绿素a量,鱼类与贝类养殖面积匹配不平衡。
Sea shellfish, fish, reed ecological farming mode, to maintain the ecological balance of the system. Through the detection of changes in the content of chlorophyll a in the system to monitor the system in each pool shellfish specifications, the amount of changes in chlorophyll a relationship. The results showed that during the system operation, the content of chlorophyll a decreased gradually from upstream to downstream. The daily consumption of chlorophyll a was over 0.3μg / L · kg-1 and the daily consumption of seedlings was 0.2μg / L · kg-1; the total amount of chlorophyll a consumed by the system is larger than the amount of chlorophyll a produced by single-cell algae, and the imbalance between fish and shellfish is unevenly matched.
