This is a picture showing the number of boats working off Kino Bay fishing grounds. Kino Bay is governed under an open access regime. Our boat counts regularly yielded 70+ boats, a symptom of their inability to control access to other fishers. As a result of the open access regime, their sea pen shell fishery (sea pen shells =a sessile mollusk that lives buried in the sand) has been overexploited. In this context, overexploitation is measured by fishers’ inability to sustain constant harvesting of sea pen shells year-round before they become too scarce and small in size. In contrast, the Seri are able to sustain their fishery year-round.
