Production of Daphnia epiphium, A method for mass production and rapid revival

A new and suitable breeding method for inducing asexual or sexual reproduction (opium pneumonia) of Daphnia Magna is described in the laboratory. Drying and dehydration cause the production of epiphium epiphium with rapid hatching. In the present study, the effect of many different parameters such as pesticides, light periods and light intensity, sediments, culture oxygen levels, dark period, and ultraviolet rays, and The effect of temperature on Daphnia production was reviewed. In the present study, it was shown that the prerequisite for finding the optimal conditions and the highest hatch rate and obtaining the optimal breeding technique need to the present studies more. But in general, in the optimal laboratory method, dormant eggs of cladoceran need a dark period of about 2 weeks (different in different species) and then drying, and then to revive that, light and oxygen conditions and free of herbicides are required.
