Embodiment 3
[0047] Comparative Test:
[0048] Using self-made high-concentration food for daphnia, daphnia food produced by BBE in Germany and live algae, the experiment of feeding daphnia was carried out in the laboratory to compare the growth and reproduction of daphnia.
[0049] The experiment was divided into 3 groups, namely the self-made daphnia-like high-concentration food-fed group, the German BBE daphnia-like food-fed group and the living algae-fed group.
[0050] The experiment was carried out in a 250ml beaker. At the beginning of the experiment, 100ml of diluent was added to each beaker. The preparation of the diluent was prepared according to the requirements in the national standard GB / T13266-91 "Water Quality-Materials to (Magna) Acute Toxicity Determination Method". Then add 4 water fleas, the age is 3 days after birth, keep the indoor temperature at 25°C, add 4μl concentrated solution every day, observe continuously for 11 days, record the growth and reproduction of water...
