Water hyacinth (Eichhornia crassipes) reveals intermittent recurring patterns of decrease and proliferation with specialist environmental and regulatory effects. This analysis intended to screen the intensity of water hyacinth impact on fishery system. The dynamics of a fisheries system in an aquatic environment with two zones: water hyacinth zone and free zone are examined in this study. Fish harvesting is permitted in both zones, and fish migration is permitted from the water hyacinth zone to the free zone but not the other way around. The dynamics of stability are shown in this study when a discrete time delay is included in the fish death rate due to oxygen depletion and water pollution produced by water hyacinth. The analysis concludes that there is a requirement for supported checking of the obtrusive macro-phytes close by environment displaying concentrates on utilizing the accessible time series information to obviously distinguish the biological variables that initiative water hyacinth dynamics and forecast all the more definitively its effect on the delayed fisheries system. To validate the analytical conclusions, numerical simulations are used.
