Latin: piscus = fish; oon = egg; dinos = armed animal.

Life Cycle

There exist two species of these so-called freshwater dinoflagellates: Piscinooodinum limneticum and P. pillularis. Size and reproduction are similar to that of Amyloodinium. However, inside the floor stage of P. pillularis only 64 swarmers are formed, while in the case of P. limneticum 256 of such dinospores are formed, which, however, lack the red eyespot that is present in the other species (Oodinium).

Symptoms of Disease

The skin of infected animals appears troubled and develops yellowish surface layers. Infected fish feed less, have problems to take up oxygen, do not grow, and start rubbing their skin at stones. Due to loss of fitness, heavily infected fish often die.
