Parasitic infections from freshwater fish are a serious problem in some parts of the world, particularly Southeast Asia. Fish that spend part of their life cycle in salt water, like salmon, can also be a problem. A study in Seattle, Washington showed that 100% of wild salmon had roundworm larvae capable of infecting people.

Myxobolus cerebralis triactinomyxon Henneguya zschokkei in salmon beard. Diseases can have a variety of causes, including bacterial infections from an external source such as Pseudomonas fluorescens (causing fin rot and fish dropsy), fungal infections (Saprolegnia), mould infections (Oomycete and Saprolegnia), parasitic disorders (Gyrodactylus salaris, Ichthyophthirius multifiliis ...
Due to the low host specificity of the parasite, Ich infection is known from all freshwater fish systems examined. However, the susceptibility and the impact differ between host species. Rainbow trout , catfish and eels are highly susceptible fish species and uncontrolled infections lead to almost 100% mortality.
Columnaris disease occurs in both wild and farmed freshwater fish and is caused by the bacteria F. columnare. The age of an infected fish impacts the course of the infection. [ 1 ] The bacteria usually enter fish through gills, mouth, or small wounds, and is prevalent where high bioloads exist, or where conditions may be stressful due to ...
