It is often assumed that placing marine reserves in locations that minimize lost fishing opportunities will reduce impacts on coastal communities, but the influence of the fishing data used on this outcome remains poorly understood. In the Madang Lagoon (Papua New Guinea), we compared three types of proxies for conservation costs to local fishing communities. We developed two types of proxies of opportunity costs commonly used in marine conservation planning: current fishing activity with fisher surveys (n = 68) and proximity from shore. We also developed proxies based on areas of importance for fishing as perceived by surveyed households (n = 52). Although all proxies led to different configurations of potential marine reserves, the three types of cost data reflect different aspects of importance for fishing and should be used as complementary measures. specialized Coral Triangle small-scale fisheries socioeconomic costs systematic conservation planning Madang Lagoon opportunity costs values PAPOUASIE NOUVELLE GUINEE MADANG LAGON 040 036 11 1 2018 1755-263X https://www.documentation.ird.fr/hor/fdi:010072333 10.1111/conl.12352 1755-263X [F B010072333] https://www.documentation.ird.fr/hor/fdi:010072333 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-02/010072333.pdf IRD - Base Horizon / Pleins textes 2018-03-05 2018-03-06 fdi:010072333 fre
