Infusoria is a collective term for minute aquatic creatures such as ciliates, euglenoids, protozoa, The culture will start to proliferate in two to three days, depending on temperature and light received. The water will first turn cloudy, but it will. Infusoria is a live food that can be used as for young fry of small fish species Culture of Infusoria Mangang College of Fisheries.

Aman Singh 1Ekta Singh 1O.
Sharma 2V. Live food organisms in this respect serve as “Living capsules of nutrition”.
Infusoria is the most primitive of all the animals of animal kingdom. Besides, they are small in size, nutritionally rich and soft bodied. Owing to these qualities they are a starter feed for early stages of fin fishes and shell fishes in hatcheries.
Cilia present on the body act as chief locomotory organ and food catching organelles. Asexual reproduction occurs by binary fission and sexual by conjugation. The most common are culturw, stylonchia.
These organisms are culture by several methods: Cover the container with cloth which will prevent the entry of mosquitoes and flies, but will allow the entry of air.
Keep the container in a cool place where natural air is available. In days the water becomes milky and emits a foul smell. This is due to multiplication of the large number of bacteria causing decay of banana pealings.
A film of slime will be formed on the water surface. In about days the water will turn clear become transparent with light yellowish colour. This is because of the floating spores of Infusoria in the air which have settled on the water feeding on bacteria which multiplies in large numbers. Subsequently, the film of the slime on the water surface breaks up and disintegrates.

The culture is then ready for early stage feeding of the fish larvae. Once the culture reaches its peak density it must be harvested. If not, the density will suddenly fall due to lack of space and oxygen depletion. The culture will sustain itself up to weeks if a few drops of milk are added.
By using hay infusion: Transfer the hay water into the jar or aquarium. After this repeat the process as described under banana pealing methods.

infusofia By using lettuce leaves: After this follow the same process as banana pealing. By using milk and milk products: Thereafter follow the same process. By using apple snail: The droppings faecal will contain half digested leaves and will give rise to a large population of Infusoria when added to the water.
In order to provide a continous supply of Infusoria it is desirable to maintain Infusoria in batch culture. Culturee is a euryhaline micro-organism, it grows and reproduces over a wide range of temperature C and salinity up to ppt. It can be cultured on various feeds fermented wheat flour.
The best results are observed at ppt and 35 to 45 C temperatures.
The generation period is hours. The best results may be obtained at 35ppt salinity and C temperature. Infusorians are photo static. In the presence of light, they come onto the surface at a high density and can be seen as film or a cluster on the water surface.

They are scooped with fine mesh nets of micro meters bolting silk cloth. Generation period of Euplotes spp. After harvest thorough washing is needed prior to feeding the early stages of fin fish and shell fishes.
