Core problem: Reduction in fishing effort required to rebuild capture fisheries to more productive levels and restore biodiversity in the project sites is likely to cause severe social dislocation unless alternative or supplementary livelihoods are available. One of the challenges facing coastal managers is to provide such alternatives, preferably in closely allied sectors such as aquaculture and coastal eco-tourism, where the skills of fishers have some application. This project will be guided by the results of Project 4, to ensure that it delivers viable livelihood options based on coastal resources or integrated land-sea activities.

Main Activities

  • Development of a range of environmentally friendly methods for profitable aquaculture, including: i) small-scale enterprises suitable for villagers focusing on high-value species low in the food chain (e.g. seaweeds, pearl oysters, sponges, marine aquarium fish, sea cucumbers, giant clams and hard and soft corals); ii) strategic research to produce a herbivorous marine fish to meet projected demands for a food when increasing pressures for freshwater limit the supply of low-cost fish from freshwater aquaculture – this will depend on crop-based diets, and may involve ―ranching‖ systems where the fish feed on ―nuisance‖ seaweeds promoted by excessive nutrients in coastal waters; and iii) polyculture to reduce disease risks and improve water quality emanating from coastal ponds. All these forms of aquaculture will be developed in ways that minimize impacts on capture fisheries.
  • Determining ―carrying capacity‖ of coastal areas for aquaculture-based livelihoods, both in terms of   competition for access from other users, and the productive limits of the ecosystem due to inputs from  a variety of other sources.
  • Ecological risk assessments for the new forms of aquaculture.
  • Integration of environmentally friendly aquaculture enterprises with eco-tourism of coral reefs to demonstrate sustainable use of resources and provide added-value commodities, e.g. shell jewelry. 

Milestones

Year 1:

  •  Development and testing of environmentally friendly methods for profitable aquaculture including   sea ranching and poly culture technologies.

Year 2:

  •  Analysis of ―carrying capacity‖ of coastal areas for aquaculture-based livelihoods including ecological risk assessment, both in terms of competition for access from other users, and the productive limits of the ecosystem due to inputs from a variety of other sources.

Key outputs

  • Sustainable methods for producing a variety of commodities from coastal waters, including new food products such as herbivorous fish, and high-value items for the pharmaceutical trade, such as sponges.
  • Assessments of the potential carrying capacity of representative coastal areas for a range of aquaculture enterprises.
  • A more diverse array of eco-tourism ventures for coral reefs.

Expected impacts

  • Creation of a broad range of options for alternative or supplemental livelihoods based on coastal resources, for poor people particularly displaced fishers.
  • Better access to animal protein through an increased supply of fish for food.
