Descriptions of environmental impact are necessary to predict the effects of specific projects on defined and often small areas, as is the case of the bay of Chancay. In this bay residual water from the fish industry and urban spilling are usually discharged. Environmental impact caused on marine sediments is deduced from an evaluation of the bio-oceanographic conditions this bay presents. Impacts generated this way vary according the environmental variable’s sensitivity or fragility, thus it is, for example, that impact on whichever of them can put the rest of the trophic chain in danger.Such is the case of this research, environmental impact is produced on the short-run and takes place when fishing industrial processing plants are working. The one on the long-run takes place due to the gathering of residues and pollutants that can become irreversible or unavoidable as time goes. The i...
