A pilot study targeting sawfishes in the southern Pilbara region of Western Australia, which is undergoing a major expansion in human activity, was conducted using gillnets during April and October 2011 in the Ashburton Estuary and adjacent mangrove creeks. Catch per unit effort was greatest in the Ashburton Estuary in October, due to an influx of green sawfish Pristis zijsron pups, and was orders of magnitude higher than previously reported for any Pristidae; the study sites contained P. zijsron up to almost 3 m total length. This study identified the first pupping site for P. zijsron in Western Australia, and the most southerly known nursery area for the species in Australian waters, and is potentially the most important globally.
在西澳大利亚皮尔巴拉地区南部针对锯鳐开展了一项试点研究，该地区正经历人类活动的大规模扩张。2011年4月和10月期间，在阿什伯顿河口及邻近的红树林小溪使用刺网进行了研究。由于绿锯鳐（Pristis zijsron）幼鱼的涌入，10月份阿什伯顿河口的单位捕捞努力量最大，且比之前报道的任何锯鳐科鱼类高出几个数量级；研究地点的绿锯鳐全长近3米。该研究确定了西澳大利亚绿锯鳐的首个产仔地，也是澳大利亚水域该物种已知最南端的育幼区，并且可能是全球最重要的产仔地。
