Cladocera

Japanese: Cladocera
Cladocera

…The larvae hatch at the nauplius or metanauplius stage. About 800 species are known, and they are classified into four orders: Anostraca (shrimps, Artemia), Notostraca (horseshobbs), Conchostraca (conch shrimps), and Cladocera (water fleas). [Shigeo Gamo]. …

From 【Daphnia (Mijinko)】

...The egg shell falls off the carapace, and the winter eggs sink to the bottom of the water still protected by the egg shell. When the environment becomes favorable, females hatch from these eggs. Cladocera have a high reproductive capacity, so they appear in large numbers as plankton in lakes and ponds, and are important as a major natural food source for fish and other creatures. For this reason, fertilization has long been used in fish farming ponds for carp, goldfish, and other fish, to artificially generate and breed large numbers of daphnia.
