Fertilization studies (Project 7.3): The fertilization of broadcast spawning corals occurs at the ocean surface where interactions with dredging plumes are likely. The objectives of Project 7.3 are to examine if success fertilization of corals gametes is affected by water quality conditions that can occur during dredging programs. Fertilization experiments will be conducted with two broadcast-spawning species and involve examining fertilization success in response to a realistic range of TSS concentrations and PSDs over an incubation period of several hours. Experiments will be conducted each year (over a 3 year period) during the coral spawning period (October-December of 2013, 2014 and 2015). The first 6 months of the project will involve developing protocols and experimental procedures and equipment to conduct the work.

施肥研究（项目7.3）：散播产卵型珊瑚的受精过程发生于海洋表层，此处极易与疏浚羽流发生相互作用。本项目的研究目标为探究珊瑚配子的受精成功率是否会受到疏浚作业期间可能出现的水质条件影响。本研究将针对两种散播产卵型珊瑚开展受精实验，通过数小时的培养周期，考察不同实际浓度范围的总悬浮颗粒物（Total Suspended Solids，TSS）与颗粒尺寸分布（Particle Size Distribution，PSD）条件下的受精成功率。实验将每年开展一次，总周期为3年，于2013年、2014年及2015年的珊瑚产卵期（10月至12月）进行。本项目的前6个月将用于制定实验方案、操作流程及搭建所需实验设备。
