The myxosporean parasite that causes whirling disease in trout, has a similar lifecycle. [35] However, as opposed to whirling disease, the Henneguya infestation does not appear to cause disease in the host salmon — even heavily infected fish tend to return to spawn successfully.
Transport of signal crayfish, red swamp crayfish and infected native European freshwater crayfish between waters is the main cause of contamination, though the disease can also be spread via items that have been in contact with contaminated water, such as a fishing tackle or footwear. [9] The spores are sensitive to high or low temperatures.
Because humans do not generally eat undercooked minnows and similar small freshwater fish, these do not represent an important source of infection. Nevertheless, these small second intermediate hosts can be eaten by larger predator species, for example trout, perch, walleye, and pike. In this case, the sparganum can migrate to the musculature ...
European settlement and the introduction of non-native species like brown trout had much to do with that. (Brown trout were despised by a great many anglers after they were brought here in the ...
The red swamp crayfish, a hand-sized crustacean the color of a fire engine, is already a problem in Florida. According to the USGS , they tend to out-eat and out-compete native crayfish, as well ...
An effective way to clear Ich from a fish population is to transfer all of the fish carrying trophonts in their skin, fins or gills to a non-infected tank every 24 hours. Then the fish do not get re-infected and after a number of days (dependent on temperature) the fish have cleared the infection because trophonts exit within this period.

[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]
