Sea Around Us Project - Relative demersal fish abundance inferred from commercial catch data, northwestern Australia (1997-2006)

This dataset describes the relative abundance of an assemblage of commercially exploited demersal fishes in northwestern Australia, mapped over a 30 arc-minute (0.5 degree) spatial grid. The data cover the period 1997-2006 and are derived from an analysis of commercial landings available through the Sea Around Us Project (http://www.seaaroundus.org/). Further methodological details can be found in the following peer-reviewed publication, which applies the same analysis to a suite of mobile pelagic species: Bouchet PJ, Meeuwig JJ, Huang Z, Letessier TB, Nichol SL, Caley MJ, Watson RA. 2016.

本数据集记录了澳大利亚西北部商业开发利用的底栖鱼类（demersal fishes）类群组合的相对丰度，以30弧分（0.5度）的空间网格开展空间制图。数据覆盖1997-2006年时段，源自对全球渔业足迹项目（Sea Around Us Project，http://www.seaaroundus.org/）公开的商业捕捞上岸量数据的分析。更多方法学细节可参阅下述同行评议学术论文，该文献采用相同分析方法研究了一类洄游远洋物种：Bouchet PJ, Meeuwig JJ, Huang Z, Letessier TB, Nichol SL, Caley MJ, Watson RA. 2016. 基于商业捕捞记录推断的远洋鱼类丰度大陆尺度热点区域. 《全球生态学与生物地理学》（Global Ecology and Biogeography）。
