Common carp are omnivorous fish and they eat any food, which can be digested. However, their habit are to dig and
burrow into the soil in search of organic matter such as larvae of insects, worms, molluscs and decayed matters
containing bottom dwelling organisms, pieces of plants the young shoots of aquatic weeds[16-18].
In case of aquarium culture, common carp fish can’t get their natural proteinous food. Therefore, the fish might not
grow satisfactorily. It also indicates that the fish growth would be better when fed with higher protein containing
feed especially animal protein. The fish growth was better when fed with cattle feed containing animal protein than
the fish fed with higher protein containing feed without fish meal. It means that the fish need higher protein
containing feed with necessary animal protein too.
