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.

该项目旨在通过增加对掠夺性鱼的生态系统需求的理解来改善经济上重要的诱饵的渔业管理。目前尚不清楚掠夺性鱼的生态系统需求，因为它没有包含少年鱼的相当大影响，尤其是当它们居住在河口时。该项目打算通过在水槽中校准的植入声发射器，以通过确定饮食饮食以及从幼体到成人的掠食性鱼类的大小和温度依赖性生长和生物遗传学来发现现场的生物能率，从河口到成人，到开放的海洋。结果包括从流域到海岸的相关浮游鱼捕食者的生态系统综合。
