Effects of different feed types and light intensity levels on the growth and reproduction of clam shrimp, Cyclestheria hislopi (Baird, 1859)

Clam shrimp (a Phyllopod order conchostraca) is a freshwater crustacean belonging to the subclass of Branchiopoda. It possesses a bivalve carapace, inhabit mainly the benthos but can swim freely in water column. Cyclestheria hislopi is the only species that has been reported to be found in perman...
