中文摘要:
      2017年7月-2019年4月期间,本研究采用大面观测、现场模拟实验、生长情况跟踪相结合的手段, 基于Dame指标和Herman模型估算了胶州湾菲律宾蛤仔的养殖容量。结果表明,调查期间胶州湾水体的叶绿素a浓度在2.09~4.28mg.m-3之间,均值为3.07mg.m-3;不同规格(壳长2.29~3.59cm)的菲律宾蛤仔单位个体的平均滤水率为0.45L.h-1.ind-1,单位重量的平均滤水率为2.52L.g-1.h-1;菲律宾蛤仔1龄、2龄和3龄的平均干重分别为0.18、0.30、0.42g;胶州湾的水团停留时间为52天,初级生产时间为1.58天,贝类滤水时间为2.09天;1龄、2龄和3龄的蛤仔养殖容量分别为637、378、272ind.m2。目前的菲律宾蛤仔养殖量已经超过养殖容量,建议若以2龄蛤为采捕对象,适宜的播苗密度为582ind.m2;若以3龄蛤为采捕对象,适宜的播苗密度为789ind.m2 。研究结果为保障胶州湾菲律宾蛤仔养殖产业的绿色高质量发展提供了理论依据和数据支撑。
英文摘要:
      During July 2017 to April 2019, this study used a combination method of large-area observation, field simulation experiment and growth tracking to estimate the carrying capacity of Manila clam(Ruditapes philippinarum) based on Dame Indexes and Herman Model in Jiaozhou Bay. Based on Dame Indexes and Herman Model, the carrying capacity of Manila clam (Ruditapes philippinarum) in Jiaozhou Bay is estimated with the comprehensive fishery survey data, field simulation experiment and growth tracking data during July 2017 to April 2019. The results showed that the average chlorophyll a concentration concentration in Jiaozhou bay was betweenin the range of 2.09 and 4.28 mg.m-3, with an average value of 3.07 mg.m-3. The average clearance rate was 0.45L.h-1.ind-1 per unit and converted to a unit-mass based value was 2.52L.g-1.h-1. per unit weight for Manila clams of different sizes (shell length between 2.29 and 3.59cm). The average dry weight of Manila clams at 1, 2 and 3 ages were 0.18, 0.30 and 0.42g, respectively. The water mass residence time was 52 days, the primary production time was 1.58 days, and the bivalve clearance time was 2.09 days in Jiaozhou bay. The corresponding carrying capacity of Manila clam at the 1, 2 and 3 ages was estimated were 637, 378 and 272 ind.m2 for 1-year, 2-year and 3-year old clams, respectively. At present, the cultivation cultured quantity of Manila clams has exceeded the carrying capacity. It is suggested recommended that if clams of 2 years old are taken as the collection object, the suitable seedlingstocking density is to be 582 ind〖?m〗^(-2) if 2-year clams are taken as the target object, and if clams of 3 years old are taken as the collection object, the suitable seedlingstocking density is to be 789 ind〖?m〗^(-2) if 3-year clams are taken as the target object. The results provide theoretical basis and necessary data support for the green and high quality development of the clam aquaculture industry in Jiaozhou bay.
