In 2007, several American states, including Michigan, enacted regulations designed to slow the spread of fish diseases, including viral hemorrhagic septicemia, by bait fish. [61] Because of the risk of transmitting Myxobolus cerebralis (whirling disease), trout and salmon should not be used as bait. Anglers may increase the possibility of ...
The cercariae penetrate further into the renal portal blood system, into the kidney and deeper tissues into the base of the tail. Penetrations sights are easily visible, as the skin, fins, and tails of the fish appear to be heavily eroded and damaged. [12] Cercariae can also indirectly infect the fish, if the fish eat the cercariae orally. [5]
Trout who swim the streams love to feed on land animals, aquatic life, and flies. [4] Most of their diet comes from macroinvertebrates, or animals that do not have a backbone like snails, worms, or insects. They also eat flies, and most people who try to use lures to fish trout mimic flies because they are one of trout's most fed on meals. [4]

Lung flukes require three different hosts in order to complete their life cycle. The first intermediate host is a snail, the second intermediate host is a crab or crayfish, and the definitive host for lung flukes is an animal or human host. [4] Intestinal flukes inhabit the epithelium of the small intestine.
Skin: Ich infections are usually visible as one or several characteristic white spots on the body or fins of the fish. The white spots are single cells called trophonts, which feed on host cells (epidermal cells and leukocytes attracted to the site) and may grow to 1 mm in diameter.
They also eat fish eggs and adult forms of terrestrial insects (typically ants, beetles, grasshoppers, and crickets) that fall into the water. Other prey include small fish up to one-third of their length, crayfish, shrimp, and other crustaceans. As rainbow trout grow, the proportion of fish consumed increases in most populations.
Myxobolus cerebralis is a myxosporean parasite of salmonids (salmon and trout species) that causes whirling disease in farmed salmon and trout and also in wild fish populations. It was first described in rainbow trout in Germany in 1893, but its range has spread and it has appeared in most of Europe (including Russia), the United States, South ...
