In the Mekong delta, inland fishing and rice production provided a major source of income for rural communities. Since early settlement, the inhabitants have caught fish. Still, fish provides the main source of animal protein in their daily diet (Madan et al. 2005). Fish are caught in flood plains and in rice fields.

CV5attonella marina, a raphidophycean flagellate, is one of the most toxic red tide phytoplankton and causes seyere damage to fish farming. Recent studies demonstrated that C7iattonella sp. generates superoxide (02'), hydirogen perexide (H202), and hydroxyl radicals ( ・ OH), which may be responsible for the toxicity ef C marina. In this study, we found that other raphidophycean fiagellates such...
