1. Introduction

In an attempt to recover fisheries resources and provide food security to communities in the Western Pacific, locally-managed marine areas have been widely promoted (Govan, 2009; Jupiter et al., 2014). Periodically harvested closures (PHCs) have become one of the most common forms of fisheries management used in locally-managed marine areas, with over 1000 closures estimated across the Western Pacific (H. Govan, pers. comm.). PHCs are generally small fisheries closures (e.g., median area of 1 km2 in Melanesia; Govan et al., 2009), with periodic harvest regimes that make them functionally similar to rotational closures (Cohen and Foale, 2013). Historically they have been applied in Pacific coastal communities to increase catch efficiency and provide for socioeconomic and cultural needs, while objectives such as sustaining small-scale fisheries and conservation of biodiversity have been proposed more recently (Cohen and Foale, 2013; Jupiter et al., 2014, 2012). The widespread use of PHCs in a region where small-scale fisheries are essential for food security (Bell et al., 2009), highlights the importance of understanding the best practice and trade-offs of PHCs for fisheries management and conservation strategies. PHCs vary markedly in the way they are managed, in particular the time they are closed versus open to fishing, which has resulted in variation in their ability to increase the abundance, size or biomass of targeted species (Bartlett et al., 2009; Cinner et al., 2006; Goetze et al., 2015; Jupiter et al., 2012). However, a recent meta-analysis found that PHCs across Melanesia were capable of providing pre-harvest protection benefits through increased abundance and biomass of targeted species, which translated into harvest benefits when opened to fishing (Goetze, 2016). The meta-analysis found that these benefits are greater in PHCs that are large, have high compliance and are closed to fishing for long periods. However, variation in these factors within Fijian PHCs has resulted in inconsistent outcomes for the abundance, size and biomassof targeted species (Goetze et al., in review). While there is some evidence for well-managed and designed PHCs providing short-term fisheries benefits prior to harvesting, a large proportion of the biomass of targeted species is usually removed during harvest events (Goetze, 2016). The ability of PHCs to recover from high levels of harvesting and their role in sustaining fisheries has not been explored empirically
