Data from: Short-term impacts and value of a periodic no take zone (NTZ) in a community-managed small-scale lobster fishery, Madagascar
The small-scale lobster fisheries of Madagascar's impoverished southeast coast account for the majority of national catch and export, making a significant contribution to the regional economy. Data suggests catches have declined, likely due to over-exploitation. In response, the community of Sa...

The small-scale lobster fisheries of Madagascar's impoverished southeast coast account for the majority of national catch and export, making a significant contribution to the regional economy.
