Fish Parasites Found in Smelts
Fish parasites are common. Most smelts have gill parasites, called copepods, which are very small insects that attach and feed on fish gills.Sometimes, nematodes, small worms, can also be found in fish guts. These parasites are intended to infect larger predators such as seals. They have no adverse effects on humans if you thoroughly cook your fish. You can further reduce parasite presence in your cooking if you cut the heads off.
