MARINE RESERVE OF OS MIÑARZOS

Page 8: Marine Reserve Galicia (May07)

A BRIEF HISTORY OF THE MARINE RESERVE OF OS MIÑARZOS

DRIVERS. October 2003

• Biological crisis due to over-exploitation affecting the artisanal fleet of the fishers’ organization (Cofradía de Pescadores) of Lira-Carnota. Marine reserves are an alternative?

• Success of the new community-based management systems implemented for some shellfisheries. Why not to expand to artisanal fleets and mobile resources?

• Previous experience in the development of projects to improve the status of the fishing sector. Active collaboration with research groups. Lonxanet, Mar de Lira, Fishing tourism, …

Page 9: Marine Reserve Galicia (May07)

OBJETIVES OF THE MARINE RESERVE

1. Restoration of over-exploited stocks

2. “Troyan horse” for a change in the fishery management system:

• Limiting effectively access

• Introducing territorial users’ rights for fishers

• Moving from command-and-control to co-management

• Some future scenarios?: From community-based to market-based mechanisms

(individual transfereable quotas) Finnancial support derived from the reserve activity

IDEA AND PROPOSAL DEVELOPED BY THE FISHERS’ ORGANIZATION

• Workshops with fishers, scientists, governement officiers and NGOs, …

IDEA AND PROPOSAL DEVELOPED BY THE FISHERS’ ORGANIZATION

• Working group including organization leaders, fishers and scientists

Page 12: Marine Reserve Galicia (May07)

IDEA AND PROPOSAL DEVELOPED BY THE FISHERS’ ORGANIZATION

• Discussions and decission-making carried out at the general assembly of the organization

Page 13: Marine Reserve Galicia (May07)

FINAL PROPOSAL OF THE FISHERS’ ORGANIZATION. 2006

Implemented officially in April 2007 as a“Marine Reserve of fishery interest”

ZONING:

1. No-take reserves: nursery habitats

2. Marine protected area:• increases in minimum sizes,• new quotas for main resources,• fleet census (future access restriction)

3. Open-access areas: “business-as-usual”

MONITORING SYSTEM

1. Assessment of the pre-reserve status of stocks and acosystems

2. Monitoring key parameters related to fishing performance, stock status and biodiversity:

BACI frameworkBefore / After + Control / Impact (reserve)

1. Development of infraestructure of geographical, environemntal and fishery data to be implemented in a Geographical Information System

HIDROACUSTIC MAPPING OF BENTHIC HABITATS

• Acoustic surveys

Page 19: Marine Reserve Galicia (May07)

HIDROACUSTIC MAPPING OF BENTHIC HABITATS• Data analysis to map functional habitats in a GIS

BIODIVERSITY, ABUNDANCE AND COMMUNITY ESTRUCTURE OF BIOLOGICAL COMMUNITIES

• Sampling design:Before / After + Control / Reserve
