Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.
Enteric redmouth disease, or simply redmouth disease is a bacterial infection of freshwater and marine fish caused by the pathogen Yersinia ruckeri. It is primarily found in rainbow trout (Oncorhynchus mykiss) and other cultured salmonids. The disease is characterized by subcutaneous hemorrhaging of the mouth, fins, and eyes.
The gas bubble disease may cause floating problems due to the excessive amount of gas in their bodies, ultimately leading to upside-down swimming and death. [3] Gas bubble disease may also occur in humans and is commonly known as decompression sickness. It generally occurs in divers when they resurface without using proper decompression procedures.
The trophont is not visible to the naked eye until it has fed on the fish and grown to a diameter of about 0.3-0.5 millimetres. The white spots may reach more than 1 mm in diameter and are easily recognized on skin and fins whereas trophonts attached to the gills are hard to see due to the gill cover ( operculum ).
