This book contains the findings of a study which was conducted for 60 days at the pond complex of the Freshwater Station of Bangladesh Fisheries Research Institute located about one kilometer away west of the Bangladesh Agricultural University, Mymensingh. The research was carried out to compare the performance of different nursing practices of giant freshwater prawn (Macrobrachium rosenbergii) post-larvae (PLs). Three treatments such as only fertilizers (T1), fertilizers with 5% supplementary feed (local feed) (T2) and 10% commercial feeds (T3) were applied in the nursing system of prawn PLs in earthen pond. The results showed that growth and survival in prawn nursery was better in commercial feed than only fertilizers and fertilizers with local feeds. So, this book will be helpful for those who are interested in prawn post larvae rearing, feeding and management in nursery ponds.
