The research work presented in this book is to promote the aquaculture in fresh water reservoir. This book describes methods currently used for the production of plant based supplementary feed in combination with animal origin feed. The present work satisfied that Common Carp fry could be successfully reared on artificial diets and also suggests that it is possible to substitute fishmeal with different aquatic weeds based fish feed. Diet formulated by more than two ingredients is better than simple diet. The results of the present work could help fish feed industrialists to prepare cheap and specific feed from the locally available aquatic weeds as raw materials for the better growth and survival rate of Common Carp and also help the fish farmers to get maximum yield in a minimum period of time. This book is an excellent resource to researchers, students, educators and fish farmers.
