Based on the data from eight seasonal oceanographic censuses in the Changjiang Estuary (28°00′-32°00′N, 122°00′-123°30′ E) in 1959 and 2002, this paper discussed temporal\|spatial distributions of Sagitta crassa and Sagitta enflata and effects of global warming on them in the Changjiang Estuary. The results show that the average abundance of S. crassa was less than 1.00 ind/m3, and its occurrence frequency was lower, had no aggregate feature during spring, summer and autumn.
