Large predatory fish are of great significance to recreational anglers, not only for their trophy status but also for their disproportional fecundity and contribution to future fishing. Remarkably, the distribution and movements of large estuarine fish in estuaries and the coastal ocean are unknown, despite their importance to the national economy. We will determine the role of freshwater discharge and oceanography on the coastal and estuarine habitat requirements, movements and home ranges of mulloway, flathead and bream from the scale of hours to years, and extend these findings to evaluate population sub-structuring and connectivity in the context of a changing climate.

大型掠食性鱼类对休闲钓鱼者至关重要，这不仅是其奖杯状态，而且还因为其不成比例的繁殖力和对未来捕鱼的贡献。 值得注意的是，尽管它们对国民经济的重要性，尽管它们在河口和沿海海洋中的分布和运动尚不清楚。 我们将确定淡水出院和海洋学对沿海和河口栖息地的要求，穆洛威，弗拉特黑头的运动和家庭范围，从数小时到数年的规模到数年，并将这些发现扩展到不断变化的气候下的人口子结构和连接性。
