Fisheries connectivity measures of adaptive capacity in small-scale fisheries

Abstract Small-scale fisheries (SSFs) around the world are increasingly facing pressures from a range of environmental, economic, and social sources. To sustain SSFs, it is imperative to understand how fishing communities adapt these pressures. In particular, manage economic risks fishers often catch many different species; diversifying harvest portfolios creates multiple income sources in case one species becomes less abundant, valuable, or otherwise unavailable. Here, we apply connectivity network analysis assess potential adaptive capacity small-scale Baja California Peninsula (BCP), Mexico. We found that metrics like modularity density varied by region through time. The Pacific coast displayed modular networks, indicating landings became asynchronous with each other increased. remaining three regions showed opposite trend, where temporal covariance between increased over Overall, this study shows varies substantially throughout BCP, highlights networks can offer way quantify advance our understanding within communities.
