Abstract: The quality situation and pollution characteristics of fishery environment in Chongqing were analyzed. The results show that the rate of test points being up to standard is low and it takes only 48.3%. The main pollutants in water are total coliform bacteria and Cu, and the main pollutants in fishery sediment are Cr, BHC and DDT. The Cu content in water is 0.04～5.21 times, total coliform bacteria in water is 0.84～3.80 times, Cr in sediment is 0.002～0.43 times, BHC in sediment is 0.03～23.88 times, DDT in sediment is 0.08～14.05 times of the standard respectively. By correlation analysis, it is shown that the more the heavy metal in sediment is, the more the heavy metal in water is. By T-test, the contents of Cu, COD_Cr and DO in water of fishing net function area are markedly higher than those in ordinary fishery function area in the secondary rivers, and the content of Cr⁶＋in water is markedly lower than that in ordinary fishery function area. The content of Hg in sediment of fishing net function area is markedly higher than that in ordinary fishery function area in the secondary rivers. The order of test points being up to standard is the general fishing zone of the second rivers＞reservoir＞fishpond＞paddy field＞net fishing zone of the second rivers.
