1 Gill flukes are âegg layersâ. 2  Depending on the temperature of the water the eggs can hatch from 4 to 30 days. 3  No treatment will terminate gill flukes in the âegg stageâ. 4  For this reason treatments must be done over a period of time and that time depends on the temperature of the water. Dactylogyrus (Dacs): are called gill flukes, however, gill flukes are also found on the body. 2  Gill flukes are âegg layersâ. 3  Depending on the temperature of the water the eggs can hatch from 4 to 30 days. 4  No treatment will terminate gill flukes in the âegg stageâ.
