WAMSI Node 4.5.2 - Modelling Recreational Fishing Behaviour

A model of recreational fisher behaviour for the West Coast Demersal fishery was developed in which fishers optimize fishing time per trip and the number of trips per year conditional on fishing opportunities, constraints on fishing and the opportunity cost of their time. To develop this model surveys were conducted and past surveys analysed. Specifically;

- a statistical analysis of a baseline data base which is prior to recent stock and rules changes in the fishery (2003 survey).

- a statistical analysis of a telephone survey of recreational fishers carried out in the 2009/10 fishing season. The survey was carried out in April/May 2010 by West Coast Field Services in a stratified random sample from the new recreational fishing licence database; and

- a final survey and statistical analysis using a telephone survey of recreational fishers in the 2010/11 fishing season. Survey was from January/February/March 2011 by West Coast Field Services.

本研究针对西海岸底栖渔业（West Coast Demersal fishery）开发了休闲垂钓者行为模型，该模型中垂钓者可在垂钓机会、捕捞作业约束及自身时间机会成本的约束条件下，优化单次垂钓时长与年度垂钓次数。为构建该模型，研究团队开展了多轮调研并对既往调研数据进行分析，具体如下：
- 针对该渔业近期种群与管理规则调整前的基线数据库开展统计分析，数据来自2003年调研；
- 针对2009/10渔季的休闲垂钓者电话调研数据开展统计分析：该调研于2010年4月至5月由西海岸现场服务公司（West Coast Field Services）执行，抽样框架为更新后的休闲垂钓许可证数据库，采用分层随机抽样方法；
- 针对2010/11渔季的休闲垂钓者电话调研开展最终调研与统计分析：该调研于2011年1月至3月由西海岸现场服务公司执行。
