Parasitic diseases are a major constraint in aquaculture as they affect fish health, growth, and survival. One common parasitic disease of fish is Ichthyophthiriasis, commonly known as white spot disease. It is caused by the protozoan parasite Ichthyophthirius multifiliis. Infected fish show small white cysts on the skin, fins, and gills resembling grains of salt. Other symptoms include excessive mucus secretion, irritation leading to rubbing of the body against hard surfaces, respiratory distress, loss of appetite, and lethargy. Heavy infection may result in mass mortality, especially in young fish. Another important parasitic disease is Trichodiniasis, caused by the ciliate protozoan Trichodina species. ___ _____ ____ ________ _________ ______ ___ _____ ___ ______ _____ _____.
