Velvet disease, also known as Rust or Gold Dust disease, originates from parasitic infection. It's caused by Oödinium, a tiny parasite belonging to several different species.
Oödinium is a dinoflagellate and therefore exhibits properties of both protozoa and algae. Here's a more detailed breakdown:
-
What is Oödinium?
- A dinoflagellate microorganism.
- Classified by some as a protozoan and by others as algae.
- Contains chlorophyll, similar to algae.
-
Where does it occur?
- Both freshwater and saltwater environments.
- Infects both freshwater and saltwater fish.
| Disease Name | Cause | Environment |
|---|---|---|
| Velvet Disease (Rust/Gold Dust) | Oödinium (parasite) | Fresh and Saltwater |
Therefore, velvet disease comes from the presence of Oödinium parasites in the fish's environment, whether it's a freshwater or saltwater aquarium or natural habitat. The parasite then infects the fish, leading to the disease.
