The purpose of the study was to analyze the current practice of shrimp farming in the north central Vietnam, to evaluate the status of agricultural production and economic conditions - social and environment, and determine the limit application of better management practices. The report presents the results of a survey of 90 shrimp farmers in north-central provinces of Vietnam (Ha Tinh, Nghe An and Thua Thien-Hue). Shrimp production costs mainly by feeding (average 65% of total cost) for different varieties of food between provinces. The purchase of seed is the second largest cost (an average of 13% of total costs) | Australian Government AusAID Ministry of Agriculture Rural Development CARD Project Progress Report 002 05 VIE Technical and economic feasibility of applying the Better Management Practices BMP to household aquaculture in Vietnam MS-3 Economic and Technical Evaluation of Shrimp Culture Management Practices in Nort Central Vietnam May 2007 1 Executive Summary The aim of the study is to analyse current shrimp farming practices in north-central Vietnam assess the status of farm production and socioeconomic and environmental conditions and identify constraints to the adoption of Better Management Practices. The report presents the findings of a survey of 90 shrimp farmers in three north-central provinces in Vietnam Ha Tinh Nghe An and Thua Thien-Hue . The cost of shrimp production is dominated by feeding averaging 65 of total costs with feed varieties differing across provinces. The purchase of shrimp seed is the second biggest cost averaging 13 of total costs . Most respondents indicated that the quality of the seed was fair on a scale from 1 very good to 4 poor the average score was . The seed quality rankings were positively correlated to the frequency of seed quality checking. Other minor costs include pond repair conducted by hired contract labour at an average of 45 000VND man-day - or man-day in April 2007 exchange rates energy use chemical and bio-product application Diatomite Zeolite and others and lime and fertilisers application urea phosphorus and NPK . Environmental testing mostly for water quality and disease checking is done by 75 of respondents. Diseases were found to be present by 75 of those respondents who conducted disease testing although this percentage is higher in provinces where disease checking is less prevalent. The average estimated loss from disease mostly through yield decreases was estimated to be 7 million VND two-thirds of the realized shrimp net revenue . Hence there is significant potential to reduce disease and increase .
