Restore nature reefs and maintaining artificial reefs

Introduction:
Small-scale artisanal fishermen in Thiruvananthapuram district have long been committed to preserving marine habitats and promoting sustainable fishing practices. Since the 1990s, the practice of deploying artificial reefs in the sea has been steadily gaining traction among local fishing villages. This initiative, which was initially led by various local organizations, has since received attention from governmental bodies. Recently, the Central Marine Fisheries Research Institute (CMFRI) has been actively involved in overseeing the establishment of artificial reefs. This report outlines the activities, outcomes, and concerns related to the deployment of artificial reefs and protection of natural reefs in Thiruvananthapuram district of Kerala, South India
Key Activities:
1. Collaboration under the Pradhan Mantri Matsya Sampada Yojana (PMMSY): In August 2023, the Association of Artisanal Fishers collaborated with the Kerala State Coastal Area Development Corporation Limited (KSCADAC) to deploy artificial reefs in the waters of Thiruvananthapuram district. This collaboration was part of the PMMSY scheme, which aims to boost the fishery sector by improving fish production and conservation efforts.
2. Local Involvement in Identifying Locations: As part of the initiative, the organization’s members assisted in identifying the most suitable locations for deploying the artificial reefs. They played a critical role in ensuring that the reefs were placed in areas with the best potential for enhancing marine biodiversity and supporting sustainable fishing practices.
3. Deployment and Monitoring: In January 2024, the artificial reefs were successfully deployed. Members of the Association of Artisanal Fishers were present to assist during the deployment process and to ensure that the operation proceeded smoothly.
Challenges and Concerns:
Despite the success of the project, members of the Association of Artisanal Fishers have raised concerns regarding the implementation of the artificial reefs. They reported that certain suggestions provided by Indigenous fishermen, who have extensive knowledge of local marine ecosystems, were not adhered to by the authorities. These suggestions could have had a positive impact on the fish production and overall effectiveness of the reefs.
Future Monitoring and Documentation:
1. Monitoring of Marine Productivity: Ongoing efforts are being made to monitor and record the production of marine organisms around the artificial reefs. The organization aims to assess the effectiveness of these reefs in boosting fish populations and improving the feasibility of fishing in the area.
2. Underwater Documentation: In collaboration with the local research group, Friends of Marine Life, the organization has begun efforts to conduct underwater documentation in December 2024. This research will help evaluate the impact of the artificial reefs on marine life and fish productivity, as well as provide valuable data for future projects.
Conclusion and Recommendations:
The artificial reef initiative in Thiruvananthapuram district is a significant step towards preserving marine biodiversity and promoting sustainable fishing practices. However, to maximize the success of such projects, it is crucial that the expertise and suggestions of local, Indigenous fishermen be more thoroughly considered. It is recommended that:
• Authorities engage in better consultation with local communities during the planning and implementation phases.
• Continuous monitoring and research be conducted to assess the impact of the artificial reefs and ensure their long-term success.
• Further efforts be made to document underwater life and fish populations in the area to gather insights that can guide future reef deployments.
