[[:Category:Nematodes|Nematodes]] infect '''freshwater, marine''' and '''brackish water fish species'''.  Pathology normally occurs within the '''intestines''' but can affect all organs and substantial damage to the host can occur. Some nematodes cause high levels of fish mortality in wild fish populations. Nematodes can infect fish as adults but larval stages of nematodes infecting piscivorous birds, mammals or reptiles, or less frequently predatory fish, can also infect fish species.
