Shrimp mortality due to luminous bacteria has been a problem of the shrimp industry worldwide. Polyculture of shrimp with finfish, such as grouper, seabass, snapper, siganid, Tilapia hornorum, and the Genetically Improved Farmed Tilapia (GIFT), could control the growth of luminous bacteria. One way to reduce adverse environmental impact and to reduce bacterial count is through the use of bivalves to filter pond effluents. This study investigated the effect of several bivalves on the growth of luminous bacteria in a simulated shrimp culture environment using concrete tanks. Tanks were stocked with shrimp at a biomass of 100 g/m3 and with brown mussel (158 pcs/m3), green mussel (137 pcs/m3), or oyster (376 pcs/m3). Growth of luminous bacteria decreased to below 101 cfu/ml in tanks with green mussel after 5 d, brown mussel after 16 d, and oyster after 17 d. Bivalves, such as green and brown mussels, and oyster, could be used as an alternative species for polyculture with shrimp to control disease due to luminous bacteria.

Milkfish and Nile tilapia are the major fishes now produced but groupers, sea bass, rabbitfish, red snappers, carps, and catfishes are grown by some farmers. The tiger shrimp is still the most important cultured crustacean, but white shrimps and mudcrabs also have great potential. Oysters and mussels are produced in considerable amounts. Mariculture of the seaweed Eucheuma is now a well established industry, and the pond culture of Gracilaria for agar extraction is beginning to take off.
Conference paperL Cheong - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - SEAFDEC Aquaculture DepartmentThe trend of fish production in Singapore is towards increasing contribution from marine and brackishwater aquaculture. Aquaculture production in 1986 represented 6.8% of local fish production. It is envisaged that this sector will provide about 37.5% of production by 1995. Freshwater aquaculture will focus mainly on production of ornamental fish. Production from farming of freshwater food fish is not likely to increase significantly. Commonly farmed marine finfishes are groupers (Epinephelus tauvina), sea bass (Lates calcarifer), and golden snapper (Lutjanus johni). Crustaceans include prawns (Penaeus merguiensis), crabs (Scylla serrata) and mussels (Perna viridis). Of the freshwater finfishes, the most commonly cultured are the grass, silver and bighead carps, red tilapia (Oreochromis niloticus hybrid), Lampam jawa (Puntius gonionotus), marble goby (Oxyleotrix marmorata) and the snakehead (Channa sp.). Aquaculture systems use a combination of floating and shorebased techniques. Earthen ponds are utilized for the culture of freshwater carps, floating netcages for marine finfish, ponds and floating netcages for marine crustaceans, and rope culture for mussels. Some research and development studies conducted presently include maturation studies to solve the problem of inconsistent supply of prawn spawners, experiments or use of dry formulated feed to do away with dependency on trash fish as main feed for grow-out marine finfish, and investigations on diseases of prawns under intensive culture. Constraints for large-scale production of finfish seeds lie in the large tank facilities required for producing live feed; for nursery operations, time and manpower required for grading and feeding; for growout systems, disease prevention and control; for prawn production, inconsistent spawner supply; and for mussel production, low consumer demand. The species with the highest potential for fanning in Singapore is the banana prawn, Penaeus merguiensis as its culture can be intensified and high yields can be obtained.

Total production in 1992 amounted to 79,699 tons valued at RM 207.4 million. These figures are 23% and 25% higher than the previous year's. Semi-culture of the cockle Anadara granosa was still predominant, contributing about 70% of the total output. Culture and production of the oyster Crassostrea iredalei is still insignificant. Sea bass Lates calcarifer constituted over 80% of the production from marine cages. Cage culture of grouper Epinephelus sp., snapper Lutjanus sp. and pompano Trachinotus blochii were also done in much smaller scale. The mangrove snapper Lutjanus argentimaculatus was recently spawned in captivity and larvae and juveniles were produced. In 1992, the tiger shrimp Penaeus monodon constituted about 87% of brackishwater pond production. Pond culture of the white shrimp P. merguiensis and the mudcrab Scylla sp. is at the experimental stage. Red tilapia hybrid was the major freshwater species cultured in cages, with 1,486 tons harvested in 1992. Freshwater pond production was valued at RM 100.85 million, 22% of which was due to the eel Anguilla japonica. Production of freshwater ornamental fishes is also becoming significant. Other exotic species recently bred and cultured are the African catfish Clarias gariepinus and the pacu Piaractus brachypomus. The indigenous freshwater catfish Mystus nemurus and carp Probarbus julleini have recently been bred in captivity and cultured experimentally. Lately, there have been attempts to culture non-conventional species such as the bullfrog Rana catesbeiana, the soft-shell turtle Trionyx sinensis, and aquatic ornamental plants.
