Condition of rocky reef communities around Tasmania: fish surveys, Australia (1992-1995 and 2006-2007)

The data is the quantitative abundance of fish derived from underwater visual census methods involving transect counts at rocky reef sites around Tasmania. This data forms part of a larger dataset that also surveyed megafaunal invertebrate abundance and algal cover for the area. The aggregated dataset allows examination of changes in Tasmanian shallow reef floral and faunal communities over a decadal scale - initial surveys were conducted in 1992-1995, and again at the same sites in 2006-2007. There are plans for ongoing surveys The originating metadata record http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=caf7220a-19e0-4a7f-9af6-eade6c79a47a contains project details, additional contacts and on-line resources.

本数据集收录通过水下视觉普查（underwater visual census）方法获取的鱼类种群定量丰度数据，该方法采用样带计数，采样点位覆盖塔斯马尼亚周边的岩礁海域。该数据集隶属于一套更大的综合数据集，后者同时对该区域的巨型无脊椎动物（megafaunal invertebrate）丰度及藻类盖度开展了调查。这套整合数据集可用于分析塔斯马尼亚浅海礁区动植物群落的十年尺度变化——首次普查于1992至1995年间开展，后续于2006至2007年间在同一采样点位完成复勘。目前已有持续开展后续普查的规划。原始元数据记录（链接：http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=caf7220a-19e0-4a7f-9af6-eade6c79a47a）包含项目详情、补充联系方式及在线资源。
