  1. RESTORATION OF AQUACULTURE IN ACEH, INDONESIA – SEAWEED IN SHRIMP PONDS Kevin Fitzsimmons and Hasanuddin Busan, Korea May 21, 2008

  2. Aquaculture in northern Sumatra • 33,000 households registered with aquaculture as primary family vocation • Family owned one hectare coastal ponds typical • Commonly used mono-culture of shrimp

  3. Lamnga, Aceh: before and after Dec 2004

  4. Damaged aquaculture ponds

  5. Problems before the tsunami • Shrimp diseases • Poor growth rates and survival • Decreasing water quality • Over reliance on single crop (shrimp) • Removal of mangroves and other estuarine vegetation

  6. Potential solutions – Sustainable coastal aquaculture • Polyculture with fish (tilapia, milkfish, grouper fingerlings), bivalves and seaweeds • Improve biosecurity (quarantine, pathogen free shrimp) • Improve water quality • Improve water management and tambak design and operations • Use mangroves to filter water and reduce erosion

  7. Recycling of wastes • Fish and shrimp discharge ammonia (NH3), CO2, phosphates and solid waste • Plants (algae, seaweeds, mangroves) use these wastes as nutrients (fertilizers) • We need to use the plants to recycle wastes and improve water quality and provide food and oxygen for animals • Bivalves (clams, oysters, mussels) filter suspended solids from water

  8. Seaweed polyculture Aceh 2007 - 2008 • Provide a more sustainable aquaculture production system for shrimp and caged fish farmers • Integrate seaweed with fish and shrimp • Gracilaria and Euchuma • Diversify production • Develop a local demand for seaweed as a new sea vegetable and source of agar for cooking and candy

  9. Workshops andtraining • Field visits to farmers

  10. Demonstration ponds stocked with Gracilaria KAB. ACEH PIDIE (5.073) Ha KAB. BIREUN(6.710) Ha Aceh Besar KAB. ACEH BESAR (3.450) Ha

  11. Initial stocks from Ohama corporate farm (1000 kg) brought to Sumatra Fresh material Material loaded from farm Gracilaria distributed into ponds

  12. Gracilaria growth between January and June 2007

  13. Fresh Gracilaria from the shrimp pond

  14. POPULATION OF KAREUNG VILLAGEBEFORE TSUNAMI : ± 400 PEOPLEAFTER TSUNAMI : 127 PEOPLE OF 57 FAMILIESSUBSISTENCE : MOSTLY FISHERS VILLAGE : KAREUNGSUBDISTRICT : LHONGDISTRICT : ACEH BESAR

  15. PLANTING OF SEAWEED (Euchuma SEED

  16. GROWOUT OF Euchuma SEAWEED

  17. SEAWEED IS READY FOR HARVEST

  18. SEAWEED HARVESTING

  19. PRODUCTION RESULTS (Euchuma SEED DEVELOPMENT) AVERAGE PRODUCTION

  20. Results

  21. Seaweed, milkfish and shrimp polyculture

  22. Agar production workshop April - May 2008 • Small scale processing of agar • Use for cooking ingredient and candy

  23. Off to the next workshop ………

  24. Presentation of results

  25. Conclusions • Shrimp and fish farms integrated with seaweed production are economically and ecologically sustainable. • International efforts required to bring diverse funding sources and expertise to assist with restoration efforts. • Still more efforts required to assist producers to apply sustainable methods.

  26. Partners • AquaFish - CRSP • Aquaculture without Frontiers • World Aquaculture Society • Professionals International • University of Arizona – Maricopa Ag Center • Network of Aquaculture Centers in Asia • YSI Aquaculture Restoration Funds • Mercy Corps • World Wildlife Fund • UN – Food & Agriculture Organization • US-Agency for International Development
