Spatial closure cost-benefit analysis.

<p>Cost : benefit curves for six of the New Zealand SPRFMO Area bottom trawl fishing areas, assuming closure of 40% of the blocks in each fishing area, and showing the decline in average, discounted habitat suitability and increase in percentage retained catch (decreasing cost to industry) as blocks of highest historical catch value are sequentially opened. The average discounted habitat suitability and percentage retained catch of current closures in each area (Penney <i>et al</i>. 2009) are shown as points on these curves. Blue dashed lines mark the position of the example optimised trade-off closure scenarios chosen for the Challenger Plateau and Northern Louisville Ridge areas, and illustrated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0082273#pone-0082273-g010" target="_blank">Figure 10</a>.
