Marine cultured species:Cockle Anadara granosaGreen mussel Perna viridisOyster Crassostrea iredalei
Disease crisis: Epizootic ulcerative syndrome in fish, MBC, Yellow head, White spot and luminescence bacteria in shrimp
Constraints:i) seed production is dependent on wild or imports ii) high feed cost
Unsustainable management practicei) indiscriminate use of antibioticii) high profit orientated leading to high stocking densitiesiii) destruction of mangrove and environmental degradation iv) discharge of untreaded pond water
Threats:i) introduction of exotic pathogensii) lack of comprehensive quarantine systemiii) lack basic health management
Fish culture has good prospect due toi) lower marine catch (more trash fish)ii) high fish importiii) health (consumers prefer fish)
PolycultureJavanese carp (surface to middle-depth, eat leaves, pellets, concentrates, grass etc)Lee koh (bottom, eat worms, decay material)Grass carp (surface, middle-depth, eat plankton, plants)Big head carp (surface, middle-depth, eat plankton)Sepat Siam (peripheral of pond, shaded with plants, eat zooplankton)
