Aquaculture in northern sumatra
Aquaculture in northern Sumatra SHRIMP PONDS

  • 33,000 households registered with aquaculture as primary family vocation

  • Family owned one hectare coastal ponds typical

  • Commonly used mono-culture of shrimp

Problems before the tsunami
Problems before the tsunami SHRIMP PONDS

  • Shrimp diseases

  • Poor growth rates and survival

  • Decreasing water quality

  • Over reliance on single crop (shrimp)

  • Removal of mangroves and other estuarine vegetation


Potential solutions sustainable coastal aquaculture
Potential solutions – SHRIMP PONDSSustainable 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


Recycling of wastes
Recycling of wastes SHRIMP PONDS

  • 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


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

Conclusions
Conclusions to Sumatra

  • 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.
