There is growing attention on reconstructing recreational catch to quantify the impacts of recreational fishing [Reference Cooke, Venturelli, Twardek, Lennox, Brownscombe, Skov, Hyder, Suski, Diggles, Arlinghaus and Danylchuk1, Reference Radford, Hyder, Zarauz, Mugerza, Ferter, Prellezo, Strehlow, Townhill, Lewin and Weltersbach6]. In the absence of quantitative catch and effort data, a time series of reconstructed catch and effort is determined from sporadic data sources [Reference Freire, Belhabib, Espedido, Hood, Kleisner, Lam, Machado, Mendonça, Meeuwig, Moro, Motta, Palomares, Smith, Teh, Zeller, Zylich and Pauly2, Reference Pauly and Zeller5]. The aim of this study was to reconstruct a time series of recreational catches for key species from a boat-based recreational fishery in the West Coast Bioregion of Western Australia from 1993/94 to 2017/18, based on data collected by various survey approaches [Reference Lai, Mueller, Hyndes and Ryan3, Reference Ryan, Hall, Lai, Smallwood, Tate, Taylor and Wise7]. Prior to the reconstruction, there was a need to develop a thorough understanding of the survey methods and the data collected to ensure scientific credibility and stakeholder acceptance of reconstruction results [...].
