Fine-scale variability in catch and growth rates of western rock lobsters (Panulirus cygnus), Western Australia (2017-2019)

A catch and markrecapture survey was conducted over 46 successive days every month over an 8-month study period between May and December in 2018. A minimum of 15 baited wooden pots enclosed by mesh were used to capture individuals at each study location, with each pot site being sampled twice on each trip. Additional markrecapture data were obtained from a simultaneous and comparable on-going research program conducted by the DPIRD (Fisheries Research) at Seven Mile Beach between May 2017 and November 2018. Historical data from a previous tagging study between November 2017 and December 2017 conducted by the University of Western Australia (UWA) contributed an additional 1682 tagged individuals.

2018年5月至12月的8个月研究周期内，每月开展连续46天的标记重捕（catch and mark-recapture）调查。各研究点位均布设至少15个带诱饵的覆网木质诱捕笼以捕获目标个体，每次采样行程中对每个笼捕点位进行两次采样。本研究额外的标记重捕数据，取自由DPIRD（渔业研究部）于2017年5月至2018年11月在七英里海滩开展的同步可比在研项目。西澳大学（University of Western Australia, UWA）于2017年11月至12月开展的既往标记研究的历史数据集，额外提供了1682尾已标记个体。
