The survey was done by a systematic sampling of shrimp hatcheries for collecting primary data. There were about 300 hatcheries in Central Vietnam of which the small scale operators were predominant. The interview was carried out with 112 hatcheries comprising 13 in Danang city, 25 in Quinhon city and 74 in Khanhhoa province. Those were considered the main areas of shrimp seed production in Vietnam. Although the basic elements of hatchery technology have been applied into Vietnam since the beginning of 1970s, it is still a new, diverse and highly risky business. As most of hatcheries are less than 5 year old, it indicated the recent rapid development of the shrimp seed production in Vietnam. This study suggests that under the present conditions in Vietnam, the small size hatcheries with a total volume of larviculture tanks of 20-25 m3 , are more suitable to management and economically viable. The water supply is becoming a severe problem in the next years because of waste disposal from hatcheries without treatment. Most wastewater is drained to sea (83 %). Deterioration of water quality and transmission of diseases are unavoidable. The survey of hatcheries shows that 35 % of hatcheries were operating at a loss in 1993. There are certain constraints for shrimp seed production in Vietnam: (1) Diseases, (2) Water pollution, (3) Broodstock supply, (4) careless use of drugs and chemicals, ( 5) Quality of feeds and chemicals, ( 6) High cost of imported goods. The priorities for improvement are: (1) Disease prevention and treatment, (2) Water treatment and pollution control, (3) Broodstock supply. Several recommendations were put forward for the development of the shrimp seed production in Central Vietnam.
