      Development of aquaculture industry in Southeast Asia: An overview 

      HR Rabanal - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Southeast Asia, a Subregion of the Asia-Pacific Region, is composed of countries of diverse socio-economic circumstances. Fisheries production, particularly that of the aquaculture sector, is relatively developed and is important to the economy of this area. Some 80 economic aquatic species are the subject of culture. Many of these species, which include fin fish, crustaceans, molluscs, and seaweeds, are produced in consequential quantities.

      Total production from the Subregion in 1983 amounted to about 880 000 mt which represented nine percent of total world aquaculture production in said year, and a 100% increase in the area within the decade (1975-1983). Unit production is comparatively low as it is usually done with the use of the extensive level of management developed after long years of experience by fish farmers. Higher rate of production in recent years is a trend especially for high value and exportable species like the penaeid shrimps. Aquaculture production tends to have accelerated growth while capture fisheries production tends to increase very gradually or levels off.

      Technical and non-technical constraints occur which hinder rapid progress of aquaculture in Southeast Asia. This will require the attention of research institutions and governments. However, bright prospects for future increase in production in this industry are developing in the area. Specific instances to support this forecast are discussed.

      Distribution and occurrence of milkfish Chanos chanos (Forskal) 

      The geographic distribution of Chanos chanos; Family - Chanidae: Order Isospondyli, is discussed from available literature sources as well as actual surveys made by the writer. The existence of the species in natural waters as well as its culture in specific areas are noted. The seasonal occurrence and distribution of milkfish fry which is the basis of aquaculture for this species is enumerated. An attempt is also made to describe the nature of distribution of the species in the countries where surveys have been made or where data is available.

      Overview of aquaculture development in Southeast Asia 

      HR Rabanal - In F Lacanilao, RM Coloso & GF Quinitio (Eds.), Seminar-Workshop on Aquaculture Development in Southeast Asia and Prospects for Seafarming and Searanching; 19-23 August 1991; Iloilo City, Philippines., 1994 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The nine countries in Southeast Asia occupy a land area of 1.85% with a population of 7.4% in the world. In 1991, these countries had a total fisheries production of 10.2 million tons or 10.5% of the world total of 96.9 million tons. In aquaculture in 1990, world total production attained 15.3 million tons (15.7% of total world fisheries production) while the Southeast Asian countries produced 1.7 million tons (11 % of total world aquaculture production). The total fisheries production in Southeast Asia which is mainly capture fisheries has continued to increase gradually by about 3.3% from 1986 to 1990 while aquaculture production has been increasing at the rate of over 8.4% during this period.The major areas for aquaculture in Southeast Asia include inland freshwaters, brackishwaters, and marine waters. Various systems exist in the region including ponds, pens and cages, delimited or fenced open water areas, and culture integrated with other production activities. Highest potential is in Seafarming while ranching is a recent innovation. The species being cultured in the region consist of about 50 fishes, 10 crustaceans, 10 molluscs, 5 seaweeds, and 5 miscellaneous aquatic vertebrates.Aquaculture will increasingly supply food and industrial products considering the worldwide levelling off of capture fisheries production. Southeast Asia has the potential to contribute substantially to this need. Support for the industry inspite of this need is inadequate to meet its technical, economic, and management problems. A sound technological base through research and training and extension needs to be pursued vigorously.
