This study was carried out from February to December 2014 by interviewing 75 farmers who opporate snakehead seed production in An Giang, Dong Thap and Hau Giang provinces, Vietnam. The results showed that the total area for snakehead seed production was 629.01±756.77 m2, whereas the area for nursing was smaller (582.1±619.8 m2). Each hatchery used 27.4±16.6 pair of broodstock/breeding cycle and produced whole year with the total of 11.3±1.17 production cycle. The productivity and the yeild of snakehead seed production was 8,375 larvae/kg and 161.44 54.64 thousand individual/production cycle, respectively. Sakehead seed was mainly sold to seed traders in the Delta (82.3%). With average production cost was 18.23±8:42 million VND/production cycle, in which variable costs accounted for 96.67% of the total cost, the farmers could reach the total net profit of 16.78±17.92 million VND/production cycle, equivalent to 185 millionVND/ year and profitable margins of 1.36. Factors of climate change affecting snakehead seed production involved rainfall, droughts, water temperature, salinity which caused diseases easier (36%), affected seed production in general (31%), decreased water quality (10%), .... To reduce the impacts of climate change to production, the snakehead seed production farmers often changed selling market, suspended production of seeds, used better brookstocks by choosing them more carefully and a number of other measures.
