An assessment of the sustainability of the Indigenous dugong fishery in Torres Strait 1997

The referenced report is presented in two sections.

The first section reports on the results of a third survey of dugong distribution and abundance in Torres Strait conducted over four days in November 1996.

The second section estimates the size of a sustainable dugong catch in Torres Strait using the Potential Biological Removal Method (PBR). The sustainability of the dugong fishery is then evaluated by comparing aerial survey estimates of the size of the dugong population in 1987, 1991 and 1996, and catch statistics from the Torres Strait Protected Zone (TSPZ) since 1991 in the context of current knowledge of dugong life history parameters.

本参考报告分为两个章节。
第一章汇报了1996年11月在托雷斯海峡开展的儒艮分布与种群数量第三次调查的结果，本次调查历时四天。
第二章采用潜在生物移除法（Potential Biological Removal Method, PBR）估算了托雷斯海峡儒艮的可持续捕捞量规模；随后结合当前已知的儒艮生活史参数，通过对比1987年、1991年及1996年航空调查得到的儒艮种群规模估算数据，以及1991年以来托雷斯海峡保护区（Torres Strait Protected Zone, TSPZ）的捕捞统计数据，评估了该区域儒艮渔业的可持续性。
