The invention discloses a method for culturing monopterus albus by a four square meters of net cage. The method includes the steps of net cage arrangement, preparation before stocking, monopterus albus breed selection and transportation, stocking, feeding, feeding management, overwintering and the like so as to obtain commercial monopterus albus. The method has the advantages that the monopterus albus obtained by the method is few in disease and high in survival rate; moving range of the monopterus albus is narrowed by the aid of the four square meters of net cage, rapid growth of the monopterus albus is benefited, and feed coefficient is low; feeding management is facilitated, labor intensity is reduced, and the method can be implemented only by one person; culturing cost is low; an overwintering method is simple and practical; sustainable market supply is guaranteed while culturing benefits are improved.
