Investigating the Effects of Environmental Factors on the Growth and Reproduction of Paramecium caudatum
摘要
Paramecium candatum is helpful for raising dragonfly naiads, namely Crocothemis servillia servillia, and can be found in freshwater ponds, pools, ditches, rivers, lakes, etc. Mosquito biological control employs dragonfly naiads. Nereiads in their early instars prefer to eat paramecium. Thus, a mass culture method for Paramecium caudatum has been established in a laboratory setting with the following parameters: 25 ± 1 °C, 75 ± 1% R.H., and a 10-hour photoperiod. Paramecium caudatum was mass-cultured in a glass tank. A glass aquarium fitted with a sliding cover, an aerator, some hydrilla plants, and paramecium food (growth medium by combining 500 g of a mixture of oats and corn husks in equal proportions, along with 50 drops of skimmed milk) was filled with ½ lit of the paramecium initial culture that was obtained using the glass jar method. The paramecium can divide itself twice or three times a day. As a result, an enormous number of paramecium can be created. The culture was utilized or changed after four to seven days of reproduction.
