In this study, the contents of heavy metals in fishing feed for aquaculture in a certain area of North China were investigated, and the environment of two aquaculture bases in this area was evaluated, providing theoretical basis for aquaculture and the guideline of production practice. The results showed that 2 in the 45 commercial feed samples were found to exceed the standard of heavy metals, with total chromium as all the items and the qualification rate of 95.60%; the exceeding sample were all carp feed, and the qualification rate was 88.20%; and the risk of heavy metal pollution in fishery feed should be paid more attention. In order to evaluate the impact of aquaculture on the environment, the contents of pollutants in sediment, background water, pond water and source water samples were analyzed, and the environmental quality assessment method was used to evaluate the pollution of heavy metals in the sediments of the aquaculture area. The results showed that the quality and safety of fishing feed products in the area were guaranteed, the pond water quality of the two aquaculture bases was better, and the potential ecological risk coefficient and ecological risk level of heavy metals pollution in sediments were lower.
