The results showed that the total area for production was 629.01±756.77 m2, whereas the volume for nursing was 582.10±119.81 m3 for pond system and 1,019.56±736.66 m3 for combining pond – hapa system). Each hatchery used 44.26±22.63 pairs of broodstock/breeding cycle and produced whole year. The quantity of seed per cycle of pond system was a half of that figure of other system while seed productivity per m3 was much lower. Snakehead seed was mainly sold to seed traders in the Delta (82.3%). With average production cost of 47.81±16.23 thousand Vietnam dong (VND)/m3, each farm in pond system could reach the total net profit of 49.83±18.74 thousand VND/m3, equivalent to 328 million VND/year. These corresponding numbers of pond – hapa system were 106.98±86.25; 196.12±87.45 thousand VND/m3, equal to 1.75 billion VND/year. Factors of climate change affecting snakehead seed production involved rainfall change, droughts, water and air temperature increase, salinity intrusion which caused  diseases easier (36%), affected seed production in general (31%), bad water quality (10%), .... To reduce the impacts of climate change to production, the farmer in snakehead seed production often changed selling market, suspended production of seeds, used better brookstocks by choosing them more carefully and a number of other measures.<br>
