Channa lucius Cuvier 1831 which belongs to snakehead is found in freshwaters like rivers, lakes, canals, rice fields and forests of nature conservation in the Mekong River Delta (MRD). Channa lucius meat that is tasty and appetizing people has respiratory organs with natural air, so it is easy to feed and the fish can live well in water from 5.5 to 6.0 low pH (Rainboth, 1996; Lee and Ng, 1994). Many people feeding fish in the MRD think that the fish has very promising development of commercial products, especially cultured in ponds, pens and cages. Currently, the main sources of Channa lucius fries are exploited naturally in small quantities and with insustainable quality. Meanwhile, the studies of this species is not much and the information is only limited in the initial basic research on biological characteristics and natural reproductive techniques. Therefore, the study of growing Channa lucius into a new cultured species which will have a great effect in the diversification of cultured species, thus contributing to reducing risks in farming and food supply needs for society, is a matter of urgency. As a result, the topic “Study of biological characteristics and seed production techniques of channa lucius Cuvier 1831” is performed.
