WAMSI 2 - Dredging Node - Theme 8 - Effects of dredging related pressures on critical ecological processes for finfish

Theme 8 was conducted in 2 phases - Project 8.1 and 8.2. The objective of Project 8.1 was to review existing literature on the impacts of dredging on critical environmental windows of finfish in both tropical and temperate areas using the steps outlined below:• identify critical ecological processes (such as spawning, recruitment and early post- recruitment growth) and associated environmental windows;• identify pressure parameters and the intensity associated with dredging;• assess likely sensitivities/tolerances of the ecological processes and windows to dredge relatedactivities; and• provide recommendations on key areas of concern and potential mitigation.The objective of Project 8.2 was to assess the information presented in the literature review and to identify (by a workshop) gaps in the knowledge and highlight priority areas for future laboratory/field experiments.

第八主题分为两个阶段实施，对应8.1项目与8.2项目。8.1项目的目标为按照下述拟定步骤，系统梳理现有关于疏浚活动对热带与温带海域有鳍鱼类关键环境窗口期影响的相关研究文献：
- 明确关键生态过程（如产卵、种群补充及补充后早期生长阶段）及对应的关键环境窗口期；
- 梳理疏浚作业的压力参数与相关作用强度；
- 评估上述生态过程与环境窗口期对疏浚相关活动的潜在敏感性与耐受度；
- 针对重点关注领域及潜在缓解措施提出建议。
8.2项目的目标为评估前述文献综述所涵盖的相关信息，并通过专题研讨会梳理现有知识缺口，明确未来实验室与现场实验的优先研究方向。
