The invention discloses a method for ecologically cultivating larva of blue crab in a pond. The traditional method for cultivating larva of blue crab has low survival rate of larva seed; in order to improve the survival rate of the offspring seed, firstly the survival rate of the crab seed from strengthened cultivation to spawning season is necessarily improved, which is taken as precondition forimproving survival rate of crab seed; and then the rational and scientific ecologic cultivation is realized to improve the survival rate of crab seed and meet the need of mass production of blue crab. The method comprises following steps: using bound seed crab rock lobster; cutting single-side eye handle, using flowing water stimulation method to improve the survival rate of broody crab to 70-80%; then propagating natural alga and using biological agent comprising photosynthetic bacteria to maintain excellent micro-ecological environment of pond, the propagation of bacteria is restrained, thetransparency is reduced, t
