What are the key points of the method for culturing paramecia?
How do you culture paramecia?
Paramecia are protozoa. Protozoa are commonly also called protists. They refer to single-celled animals whose entire body is one cell. The individuals are relatively small, and generally difficult to see with the naked eye. Although some species are visible to the naked eye, their external form still cannot be clearly distinguished. But they are all good live food for feeding ornamental fish fry. Their culturing methods are all relatively simple, and the scale can be large or small depending on need.
Culturing paramecia: Paramecia are light-loving by nature and generally live in lakes and ponds. In places rich in humus and in hay infusion, they reproduce especially vigorously. The suitable temperature is 22°C~28°C. Put pond water in a glass culture jar; if there are tiny white dots swimming in the water layer, that indicates their presence. When they reproduce in large numbers, they drift or swirl in the water layer as grayish-white cloudiness, which is why they are also called "hui shui" (infusoria water). When culturing, take the infusoria water as the seed source. Another method is to take about 70 cm of rice straw rope, cut it into several short pieces and place them in a glass jar, then add about 5 L of water, introduce a small amount of seed source, and then place the glass jar in a place with relatively sufficient light. Cultured at a water temperature of 18°C to 24°C for 6 to 7 days, paramecia can reproduce in very large numbers. When the reproduction quantity reaches its peak, if they are not harvested in time, most will die the next day, so they must be harvested every day. The harvested amount should preferably be 1/3 to 1/2. At the same time, replenish the culture liquid, that is, add new water and fertilize with rice straw. By continuously culturing and continuously harvesting in this way, live food can be provided continuously.
