Feeding Common Carp Fish (Cyprinus Carpio) on Natural foods (Algae, Phytoplankton, Zooplankton and others) on Tigris River in Mosul Dam / Duhok, Kurdistan Region of Iraq

Abstract

This study is the only study research that has been done on Tigris River in Mosul Dam (Duhok Governorate, Kurdistan Region of Iraq). The main aspect is to Keep Common Carp Fish in Ceramic pond without feeding them any Artificial Feed (Feed concentrate); only depending on natural feeds (algae, Phytoplankton and Zooplankton). At the beginning we thought that fish will lose their weight because of consuming the storage of energy, carbohydrates and others nutrients from muscle and other parts of body, but the result shows opposite, and it increases body weight slightly. This indicates that the water contains many natural foods (algae, phytoplankton, zooplankton and others). Perhaps this reflects types, level and source of water, plankton variety to name but a few of the variables that could be investigated. Other studies could examine the following. It also led us to follow up the research, recording more data and continuing research in the future.
