中文摘要:
      基于2019年莱州湾芙蓉岛人工鱼礁区渔业资源调查数据,利用Ecopath with Ecosim 6.6(EwE)软件构建了芙蓉岛人工鱼礁区生态系统Ecopath模型,系统分析了芙蓉岛人工鱼礁区生态系统的能量流动规律和结构特征,估算了仿刺参(Apostichopus japonicus)的生态容量。Ecopath模型由16个功能组组成,基本涵盖了芙蓉岛人工鱼礁区生态系统能量流动的主要过程。结果发现:生态系统各功能组的营养级范围为1.000~3.978,其中花鲈(Lateolabrax maculatus)处于最高营养级;生态系统总转换效率为10.6%,来自初级生产者的转换效率为10.8%,来自碎屑的转换效率为10.1%;生态系统总流量为2596.108 t·km-2·a-1,其中44%来自碎屑;系统总初级生产量/总呼吸量为1.454,连接指数为0.402,系统杂食指数为0.211,Finn’s循环指数和平均路径长度分别为8.86%和2.98。结果表明,芙蓉岛人工鱼礁区生态系统成熟度和稳定性较低,食物网结构较简单。根据模型计算得出,仿刺参的生态容量为131 t/km2,是现存量的6.55倍,具有较大的增殖潜力。
英文摘要:
      By investigating the fishery resources in Furong Island, Laizhou Bay artificial reef in 2019, the energy flow and the structure of the ecosystem were modeled and the ecological capacity of Apostichopus japonicus was estimated using an Ecopath model (EwE 6.6). The model included 16 functional groups which basically covered the main processes of the energy flow in Furong Island artificial reef ecosystem. According to the results, the trophic levels of the functional groups varied from 1.000 to 3.978, and Lateolabrax maculatus occupied the highest trophic level. The total transfer efficiency was 10.6%, and the proportions of the total flow originated from primary producers and detritus were 10.8% and 10.1%, respectively. The total system throughput was estimated to be 2596.108 t·km-2·a-1, with 44% originated from the detritus. The ratio between the total primary productivity and the total respiration of the system was 1.454, the connectance index was 0.402, the system omnivory index was 0.211, and the Finn’s cycling index and Finn's mean path length were 8.858% and 2.981, respectively. The results showed that the Furong Island artificial reef ecosystem was under a relatively low maturity and stability level with a relatively simple food web. The ecological capacity of the Apostichopus japonicus estimated by the model is 131 t/km2, which is 6.55 times the existing stock, with a greater potential for the growth of Apostichopus japonicus. According to actual production situation, the ecological balance of the ecosystem can be maintained with the annual catch of 4.1 t/km2. At present, there are few studies on ecological effect evaluation and ecological capacity evaluation of artificial reef using Ecopath model at home and abroad, and there is little discussion on fishery management model. More application and verification of artificial reef are needed. This study is expected to provide scientific basis for ecological effect evaluation of artificial area and sustainable utilization of marine ranch.
