      Guidelines for the development of environmentally acceptable coastal aquaculture 

      Southeast Asian Fisheries Development Center, Aquaculture Department - Aqua Farm News, 1995 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The paper presents some recommendations for the development of the environmentally acceptable coastal aquaculture such as: 1) Formulate coastal aquaculture development and management plans, 2) Formulate integrated coastal zone management plans, 3) Apply the environmental impact assessment(EIA) process to all major aquaculture proposals, 4) Select suitable sites for coastal aquaculture, 5) Improve the management of aquaculture operations, 6) Assess the capacity of the ecosystem to sustain aquaculture development with minimal ecological change, 7) Establish guidelines governing the use of mangrove wetland for coastal aquaculture, 8) Establish guidelines for the use of bioactive compounds in aquaculture, 9) Assess and evaluate the true consequences of transfers and introductions of exotic organisms, 10) Regulate discharges from land-based aquaculture through the enforcement of effluent standards, 11) Establish control measures for aquaculture products, 12) Increase public awareness of the safety aspects of consuming seafood, 13) Apply incentives and deterrents to reduce environmental degradation from aquaculture activities, and 14). Monitor for ecological change.

      The use of chemicals in aquaculture in Malaysia and Singapore 

      S Mohamed, G Nagaraj, FHC Chua & YG Wang - In JR Arthur, CR Lavilla-Pitogo & RP Subasinghe (Eds.), Use of Chemicals in Aquaculture in Asia : Proceedings of the Meeting on the Use of Chemicals in Aquaculture in Asia 20-22 May 1996, Tigbauan, Iloilo, Philippines, 2000 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Aquaculture is an increasingly important force in both the Malaysian as well as the Singaporean economies. In recent years, Singapore has focused on the aquarium fish trade, making it one of the largest ornamental fish production and transhipment centers in the world. Similarly, the Malaysian aquaculture industry has made rapid strides in the last few years and is poised to become a major contributor to the national fish supply by the early part of the next century. A significant trend in both countries has been the growing intensification of culture systems to achieve higher production per unit area. This has led to a greater occurrence of disease, particularly among aquarium fish, shrimp and marine fish farms. To obviate and control these diseases, there has been a concurrent increase in the use of chemotherapeutants. The three major groups of commonly used chemotherapeutants are: topical disinfectants, antimicrobials and probiotics. There is a wide range of topical disinfectants used by aquafarmers. The most common of these include lime, teaseed cake, formalin, benzalkonium chloride, acriflavine, malachite green, hypochlorite and poly-vinyl pyrrolidine. Of these, lime and teaseed cake are used exclusively in ponds, and acriflavine and malachite green only in hatcheries, while the others are used in both systems. Antimicrobials being used include sulfonamides, tetracyclines, nitrofurans, chloramphenicol, oxolinic acid and virginiamycin. A number of other chemotherapeutants are also used, albeit on a limited basis. The current concerns surrounding the use of chemotherapeutants and the legislative framework surrounding their sale and distribution are also discussed.
