Synopsis (short abstract) Thailand experienced several cycles of rapid expansion and intensification of production, followed by sector-wide losses from a series of viral disease outbreaks. Farms were forced to innovate and adapt management measures to address the perceived sources, or drivers, of disease. The implementation of heterotrophic, low water exchange shrimp-farming systems – including the use of biofloc – in Thailand has helped to limit the spread of pathogens and improved farm performance. Techniques include: on-farm recirculation and natural treatment of pond water, a move to lined ponds, and use of strong aeration and water currents to keep biofloc in suspension, among others. The systems can produce more aquatic foods sustainably, with minimal water exchange, less sludge and pond wastes and also improve farm profitability. They also provide both a low-cost and natural method of treating and improving the water quality in grow-out ponds, and simultaneously provide an additional cost-saving food source.

    Pathology, disease prevention and water quality (prawn farming in Thailand) 1980
    Also available in:
    No results found.
    This working paper contains the reports of two consultants to our project who advised on related topics. The first report (pp 1–39) is that of Dr. S. (Ken) Johnson of Texas A & M University who spent one month in Thailand in June/July 1980. During this time he also provided assistance to project THA/75/012 (Pond Management and Fish Diseases) and to marine shrimp workers in the Brackishwater Fisheries Division of the Department of Fisheries. The second report (pp40–45) was provided by Dr. Pau l A. Sandifer who was in Thailand for only 10 days, including five during which he participated in the meeting Giant Prawn 1980 and presented two papers2 on his work at the Marine Resources Research Institute in Charleston, South Carolina. In addition to presenting papers at Giant Prawn 1980, both Dr. Johnson and Dr. Sandifer chaired sessions at the meeting and contributed enthusiastically to formal and informal discussion sessions. Their visits to Thailand were well appreciated here.

    Report to the government of Thailand on shrimp farm development 1973
    Also available in:
    No results found.
    The report gives an account of shrimp farm development investigations, including small-scale larval culture experiments in which five species were grown to post-larval size from eggs spawned in the laboratory. The results of two experiments to test the efficiency of fertilizer to increase pond production are reported. Production was greater with ammonium sulphate and superphosphate than with superphosphate alone. Application of tea-seed cake at rates of 25 parts per million (ppm) and 10 ppm was effective in eliminating fish from shrimp ponds without damaging the shrimp. Research to produce shrimp in hatcheries should be conducted, but it is important that pond management skills be developed before additional shrimp from hatcheries are provided to traditional type farmers. Suggestions which might assist in improving shrimp farming have been indicated. Supplemental feeding is not considered necessary at this stage of development in the traditional practice of shrimp farming in Thailand. Sufficient food can be supplied by fertilization of pond waters. The most immediate need is to determine what types of fertilizer are appropriate for Thai waters, and their proper rates of application.

    Brine shrimp (Artemia salina) inoculation in tropical salt ponds: a preliminary guide for use in Thailand 1979
    Also available in:
    No results found.
    This work paper is prepared in view of the wish of the Thai Department of Fisheries to inoculate salt ponds with Artemia salina to produce cysts. Artemia cysts are used to obtain live food in many aquacultural operations, but especially in the hatchery of the giant freshwater prawn, Macrobrachium rosenbergii. These inoculations, if successful, could encourage the Thai Government in the future to conduct experiments in large-scale cyst production. Indeed, up to this date, Thailand completely de pends on import of expensive Artemia cysts from abroad. The yearly expenditure in cysts by the Department of Fisheries for the national fisheries stations, is estimated to be more than US$50 000. The inoculation ponds considered are: (i) ponds in the National Fishery Station at Samut Sakhorn (still to be completed), and (ii) privately-owned salt ponds of salt farmers in the vicinity of the National Fishery Station at Chachoengsao. Although previously, several inoculations in other parts of t he world have proven to be successful, no written guides are yet available. Trial inoculations in Thailand being considered important, the necessity was felt to gather all available information on Artemia inoculations and cyst production into one working paper to serve as guide on improving the chances of a successful experiment.
