Green Crab Monitoring Data, Tasmania, 1996-

Dataset contains monitoring data from field surveys (mainly from crab-traps) on the distribution of European green crab (Carcinus maenas) in Tasmanian coastal waters, from January 1996 onwards. Data are also collected for bycatch of native crab species (including common shore crab Paragrapsus gaimardii, rough rock crab Nectocarcinus integrifrons, and ocean surf crab Ovalipes australiensis). The majority of data comes from keysites on the north-east (Georges Bay, Falmouth) and south-east (Little Swanport, Blackman Bay, Norfolk Bay) coast which are surveyed each late Spring to early Autumn (initially fortnightly, later monthly, most recently bimonthly). Data contains details of catch location, date, crab species, crab size, abundance, sex, gonad condition, limb loss, carapace colour. These data are collected as part of CSIRO's studies on the impacts and demographics of introduced marine species in Australian waters.

本数据集收录了1996年1月起针对塔斯马尼亚沿海水域欧洲青蟹（Carcinus maenas）分布开展的野外调查监测数据，调查以蟹笼为主要采样手段。同时同步采集了本土蟹类的兼捕数据，涉及常见滨蟹（Paragrapsus gaimardii）、粗糙岩蟹（Nectocarcinus integrifrons）以及澳洲梭子蟹（Ovalipes australiensis）。
绝大多数数据采集自东北海岸（乔治斯湾、法尔茅斯）与东南海岸（小天鹅港、布莱克曼湾、诺福克湾）的核心监测站点，上述站点的监测周期为每年晚春至初秋，初期采样频率为每两周一次，后调整为每月一次，当前为每两个月一次。
数据集涵盖捕捞点位、采样日期、蟹类物种、个体尺寸、种群丰度、性别、性腺状态、附肢缺损情况以及甲壳颜色等详细信息。
本数据集为澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）针对澳大利亚海域外来海洋物种的生态影响与种群特征开展的研究项目的一部分采集所得。
