Changes

Members of the ''Dactylogyrus'' species prefer to live on the '''gills of host fish''', most often '''cultured Cyprinids''' (common carp, grass carp, silver carp). The adults are '''oviparous''' and the eggs are released into the water to hatch. These eggs are often very resistant and can survive chemical treatment. The emerging ciliated larvae are carried to a new host by water currents and by their own movement.

The maturation time of ''Dactylogyrus'' species from egg to adult '''depends on the temperature'''. At approximately 20°c it only takes a few days, but at approximately 2°c it can take several months.

The adult fluke attaches itself to its host by the '''opishaptor''' which hooks into the surface of the skin. The flukes live on mucus and skin debris and in small numbers do not seem to cause any harm.

Chemicals are the main method of treatment and control.

'''Chemical treatments''' via dips of baths in '''salt, formaldehyde or organophosphates''' are all possible.

'''Potassium permanganate''' is also effective and is the treatment of choice if bacteria or fungi are invading the damaged tissue.
