Abstract

Small-scale fisheries are large contributors to regional economies and livelihoods in coastal communities of Latin America. While Mexico is one of the cases where small-scale fisheries play an important role, overfishing and poor management strategies have led to the collapse of many of its fisheries. The callo de hacha scallop fishery of the Ensenada de La Paz in Baja California Sur is an example of such a fishery which, after years of mismanagement, was closed by the Mexican authorities in 2009. The present study evaluated the recovery efforts in the cove and the potential outcomes of a collaboration between a non-governmental organization and a fishing community working towards the restoration of this pen-shell fishery. After more than four years of closure and active monitoring of the recovering process, the callo de hacha population has shown a significant population recovery, with potential solvency for reopening fishing activities. Four scenarios of uncertainty are evaluated with two of them providing positive net present values from reopening the fishery. We also document the involvement of a non-governmental organization with a fishing community, which created social capital and, in our opinion, was essential for a successful restoration. Having an actively involved community helped raise funds for the fishing closure so fishers were able to comply with Mexican legislation; it also fostered community building and self-organization that will be crucial to maintaining the sustainability of the fishery.
