Following the planned FAO Ecosystem Restoration Programme for estuarine habitats to support estuarine fisheries and early life stages of estuary-dependent marine fish, direct relationships of total seagrass and eelgrass Zostera m. capricorni areas and biomass with fish harvest were derived for a range of slightly to highly urbanized coastal lagoons that are expected to support the larvae and juveniles of estuary-dependent marine fisheries. Fish harvest and seagrass area and biomass in the lagoons increased with moderate catchment total suspended sediment and total phosphorus loads due to lagoon flushing rates directing excess silt and nutrients out to sea via the lagoon entrances. Well managed, sewered catchment management works are shown that could assist estuary managers maintain seagrass for estuarine and offshore estuary-dependent fisheries by maintenance of seagrass and fishery ecological processes. Further research is suggested to investigate estuary-dependent post-juveniles leaving estuaries and lagoons migrating to nearshore, offshore and shelf marine fisheries.
根据粮农组织计划的沿海生境生态系统恢复计划，以支持沿海渔业和依赖河口的海洋鱼类的早期生命阶段，为一系列轻度到高度城市化的沿海泻湖得出了总海草和鳗草 Zostera m. capricorni 面积和生物量与鱼类收获的直接关系，这些泻湖预计将支持依赖河口的海洋渔业的幼虫和幼鱼。由于泻湖的冲洗速度通过泻湖入口将多余的淤泥和养分导向大海，因此，泻湖中鱼类收获以及海草面积和生物量随着流域中总悬浮泥沙和总磷负荷的适度增加而增加。研究表明，经过良好管理、有污水管道的集水区管理工程，可以通过维持海草和渔业生态过程，帮助河口管理者为河口和近岸依赖河口的渔业维持海草。建议进一步研究离开河口和泻湖的依赖河口的幼鱼向近岸、近海和大陆架海洋渔业迁移的问题。
