This project aims to improve fisheries management of economically important baitfish by increasing our understanding of the ecosystem demand of predatory fish. The ecosystem demand of predatory fish is currently not understood, because it fails to include the considerable impact of juvenile fish, especially when they reside in an estuary. The project intends to implant acoustic transmitters, calibrated in a flume, to discover bioenergetic rates in the field by determining the diet and the size- and temperature-dependent growth and biogenetics of a predatory fish species, from juvenile to adult, from estuary to the open sea. The outcomes include an ecosystem synthesis of related pelagic fish predators from catchment to coast.

该项目旨在通过提高我们对食肉鱼类生态系统需求的了解，改善对经济上重要的诱饵鱼的渔业管理。食肉鱼类的生态系统需求目前还不清楚，因为它没有包括幼鱼的相当大的影响，特别是当它们居住在河口时。该项目打算植入声波发射器，在水槽中校准，通过确定一种掠食性鱼类的饮食、大小和温度依赖的生长和生物遗传学，从幼年到成年，从河口到公海，来发现野外的生物能量率。结果包括从集水区到海岸的相关远洋鱼类捕食者的生态系统合成。
