Silvofishery in Pangkalan Siata: A Sustainable Approach to Shrimp and Crab Farming
Silvofishery in Pangkalan Siata: A Sustainable Approach to Shrimp and Crab Farming In Pangkalan Siata village, our efforts in 2023 marked a significant stride in sustainable aquaculture, focusing on silvofishery as a part of our comprehensive 001-OxC Designed Project Activities. This initiative aimed to integrate sustainable practices in shrimp and crab farming. Key Highlights of the Project Educating and Empowering Pond Owners: We provided extensive silvofishery training to pond owners, covering the basics and complexities of sustainable farming methods, including the definition, components, benefits, and management practices of silvofishery. Land Assessment: Working closely with the pond owners, we assessed the suitability of their ponds for silvofishery. The assessment showed a main pool of 5 hectares, three connected foster pools, concrete floodgates, favorable water quality, 60% mangrove cover with species like Rhizophora and Avicennia, and overall good pond condition. Monitoring and Challenges: Our monitoring in August 2023 revealed a drop in water pH to 6.5, changes in salinity and temperature, and limited shrimp growth of only 1.5 cm over 1.5 months. We identified low-quality broodstock and Enterocytozoon Hepatopanaei (EHP) disease as the main challenges. Proactive Harvesting Decision: Due to these challenges, we decided on an immediate shrimp harvest, timed for the third week of August to coincide with the big tide season. Facility Handover and Seed Quality Improvement: We handed over pond facilities to the silvofishery group and discussed sourcing higher-quality shrimp seeds from Langsa, Aceh, to address the issues with shrimp seed development. Ongoing Monitoring Commitment: Regular monitoring will continue until harvest to ensure the development of the shrimp and the adaptation of strategies as needed. Our engagement in Pangkalan Siata reflects a deep commitment to sustainable aquaculture. By educating local communities, providing essential resources, and adapting to environmental challenges, we’re not only fostering a successful harvest but also instilling long-term sustainable practices. This project goes beyond aquaculture, aiming to create a harmonious balance between economic success and environmental stewardship.
