Low levels of chemical pesticides occur in water supplies such as ponds and lakes, which provide habitats for many fish species.This results in death of some fish fry (first-year fish), loss of some insects and invertebrates that serve as fish food, and depleted oxygen concentrations due to decomposition of algae killed by herbicides.These effects suggest that the presence of low-level pesticide residues in water supplies acts as a _______ to fish populations.
