Increasing numbers of people like to go fishing, and to catch a fish, which translates into tourism income and aquaculture business. Restocking is a fisheries management option when the natural supply or survival of larvae is limited. This study will determine for the first time the ecologically appropriate abundance of small mulloway and prawns that an estuary can sustain. We will assess the extra effort needed to release larvae into particular key habitats, and develop new technologies to identify our larvae from the wild. Our findings will be relevant to restocking of Australia's inland rivers, which at present has little ecological basis.

越来越多的人喜欢钓鱼，喜欢钓鱼，这转化为旅游收入和水产养殖业务。在幼体自然供应或存活有限的情况下，重新放养是一种渔业管理选择。这项研究将首次确定河口所能承受的小型梭鱼和对虾的生态适宜丰度。我们将评估将幼虫释放到特定关键栖息地所需的额外努力，并开发新技术来从野生环境中识别我们的幼虫。我们的发现将与澳大利亚内河的补给有关，目前这些内河几乎没有生态学基础。
