Despite its high conservation status and importance to commercial and recreational fisheries, seagrass is still declining in Australian waters. By investigating a trophic cascade that links nutrient pollution to the growth and survivorship of seagrass and commercially-important juvenile fishes, our study fills knowledge gaps crucial for improved future management of seagrass habitats. The primary outcome of this study will be a model that can predict how changes in nutrient pollution will influence population dynamics of commercially-important fish species supported by seagrass. This information has, therefore, direct relevance to managers of estuarine and coastal environments at all levels of government - local, state and federal.

尽管海草的保育地位很高，对商业和休闲渔业也很重要，但澳大利亚水域的海草数量仍在减少。通过研究将营养污染与海草和具有重要商业价值的幼鱼的生长和生存联系起来的营养级联，我们的研究填补了对改善未来海草栖息地管理至关重要的知识空白。这项研究的主要结果将是一个模型，该模型可以预测营养物质污染的变化将如何影响海草支持的具有商业重要性的鱼类物种的种群动态。因此，这些信息与各级政府--地方、州和联邦政府--的河口和沿海环境管理人员有直接关系。
