Estuaries are iconic recreational areas providing both ecological habitat and millions of dollars in revenue to the tourism and fisheries industries. How estuaries respond to human pressures is highly variable with some such as the Gippsland Lakes succumbing to algal blooms, whilst other heavily nutrient laden systems such as the Werribee Estuary support extremely high fish populations. This project aims to lead to an understanding of the links between freshwater flow, blue-green algal blooms, and recruitment of a key fishery species, black bream. The outcome of the project aims to give catchment managers greater confidence in setting levels of environmental flows that will both support fish populations but also mitigate against algal blooms.

河口是标志性的休闲区，为旅游业和渔业提供生态栖息地和数百万美元的收入。河口对人类压力的反应是高度可变的，一些如吉普斯兰湖屈服于藻华，而其他营养丰富的系统，如Werribee河口，支持极高的鱼类种群。该项目旨在了解淡水流量、蓝绿色藻华和关键渔业物种黑鲷的补充之间的联系。该项目的成果旨在使流域管理者更有信心设定环境流量水平，既支持鱼类种群，又减轻藻类水华。
