I cannot find any information on "Israeli carp" per se but I have some information on the common carp.
The common carp is an omnivore, a creature that eats both plants and animals. Carp live in rivers, streams and lakes, feeding on anything that tastes good to them. A typical carp will eat aquatic plants, insects, crayfish, dead fish, mollusks such as freshwater clams and nuts that fall from trees into the water.
