摘要

淡水贻贝 Sinanodonta pacifica 被无意引入印度尼西亚后，迅速扩散。人们对该物种在印度尼西亚各地的生命周期和繁殖特点知之甚少。要管理该物种并减轻其可能对本地生态系统造成的负面影响，我们需要这方面的信息。我们首先通过时间监测、组织学调查、光镜和扫描电子显微镜相结合的方法，报告了太平洋贻贝的繁殖生物学特性，并将贻贝密度及其繁殖和胚胎阶段与西爪哇海拔 67 米至 1,580 米五个地点的环境变量联系起来。太平洋贻贝（Sinanodonta pacifica）为原生贻贝，全年都能产卵和繁殖幼体，产卵高峰期为 9 月至 12 月的早期雨季。中原地区的河蚌产卵量是低地或高原地区河蚌的 4.1-8.9 倍；高原和低地河蚌的雌雄同体产卵量是中原地区河蚌的 3.1-4.3 倍。悬浮固体含量高和叶绿素-a 浓度低会导致雌雄同体比例增加和球雌贻贝产量减少。贻贝密度低和性别比例失调也会导致雌雄同体比例增加和球雌贻贝产量减少。这些结果加深了我们对太平洋贻贝如何跨海拔繁殖以及种群增长如何威胁本地物种和自然生态系统的理解。建议采取的管理措施包括定期收获贻贝以控制种群数量，并促进珍珠生产带来的经济效益。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
