Fish medicine
a medicinal herb easily available in India can increase the resistance to disease and ensure better growth among some of the commonly consumed fish, according to a recent study by scientists at the Delhi University.
Rina Chakrabarti and Vasudeva Rao studied the effect of Achyranthes aspera on Catla catla (commonly called catla) and Labeo rohita (rohu), both of which are freshwater fish. The roots and seeds of the plant were grinded and mixed with the fish feed. The scientists observed an increase in growth as well as resistance to infectious diseases in the fish, which, they say, was a result of the plant enhancing both their specific and non-specific defence mechanisms. The findings were recently published in two journals
