ABSTRACT
Introduction Fishing on coral reefs in the Western Pacic region has been practiced by the indigenous people of American Samoa, Guam, the Commonwealth of the Northern Mariana Islands (CNMI), and Hawaii for more than 3 millennia (Dye and Graham 2004). This practice is embedded in the fabric of the local cultures and traditions despite changes in socioeconomic and sociocultural conditions brought about by urbanization and Western inuence (Allen and Amesbury 2012, Levine and Sauafea-Leau 2013). In an age of globalization and modernization, coral reefs and associated sheries are being threatened from multiple fronts and on multiple scales: land-based pollution resulting in phase shifts (Pastorok and Bilyard 1985, Hughes 1994, Edinger et al. 1998), global warming coupled with climate change (Brander 2007, Munday et al. 2008), and destructive shing combined with overexploitation (e.g., Edinger et al. 1998, Jackson et al. 2001, Newton et al. 2007, McClanahan et al. 2008). The multidimensionality of the coral reef sheries poses a signicant challenge to management, hence multiple tools have been developed to address the various impacts affecting the sheries. These management tools range from spatial-temporal managementlike rotational closures or permanent no-take marine protected areas (Roberts and Polunin 1993) to traditional shery tools such as input controls (e.g., gear restriction, limited entry program, and effort limits) and output controls (e.g., size limits, bag limits, seasonal

closures, and catch limits). All these tools are geared toward conserving and managing stocks that are regarded as being in decline on a regional and global scale (Pandol et al. 2003, Newton et al. 2007, Zeller et al. 2007, Worm et al. 2009).
