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.
