Comprehensive Management for the Use and Recovery of Scallop Populations in the Midriff Island Region, Sonora

Gulf of California Rocky Reef

Sustainable Fisheries

OBJECTIVE: To develop a sustainable fishery management model for the usability of pen shells (Atrina tuberculosa) and wing-oysters (Pteria sterna) in Bahía de Kino and Puerto Libertad, Sonora.

Scallop fishery has taken place in Sonora since the mid-20th century. In the last few decades, interest in these resources has increased thanks to an appreciation for the consistency and flavor of scallops. Scallops are considered a seafood delicacy.

Since the 1970s, overfishing has caused drastic drops in catch numbers, local extinction in specific banks, and has precluded the natural recovery of the two species. The overexploitation of these resources has occurred mainly due to scant regulation, an open access situation, and overcapitalization in the fishery. To fix the current crisis, producers are seeking alternatives to ensure the sustainable management of these resources.

Since 2014, two cooperatives – Ecopescadores (Bahía de Kino) and Paredones de Punta Cirio (Puerto Libertad) – have been implementing a “comprehensive management” project for pen shells (Atrina tuberculosa) and wing-oysters (Pteria sterna). The cooperatives obtained a concession, which gives them exclusive access to an area of 25.91 hectares in Bahía de Kino and 31.42 hectares in Puerto Libertad.

The producers also identified three fishery management tools they wanted to use in the area awarded:

1)         Fishery refuge zones (no fishing areas) corresponding to 30% and 33% of the total area in Bahía de Kino and Puerto Libertad, respectively.

2)         Management of quotas representing 32% and 33% of the awarded area in Bahía de Kino and Puerto Libertad, respectively.

3)         Restoration zone for mariculture, which will involve the capture of larvae from the natural environment, growth of organisms, and cultivation in the seabed. This area represents 37.5% and 34% of the total awarded areas, in Bahía de Kino and Puerto Libertad, respectively.
