Abstract
The nutritional food security is a vital challenge at present for every population of India .Enhancement of freshwater prawn and fish production by utilizing our vast resources both in fresh water as well as brackish water is, badly needed to meet the challenge of today. Suddenly swiss over to fresh water prawn production by the entrepreneurs became a matter of concern due to spreading over of viral disease by P. monodon (brackish water sps.) during post nineties. Also the verdict of Supreme Court on CRZ issue made many low saline areas idle which subsequently turned to M. rosenbergii farming. The reliable Scampi seed production by the successful captive breeding during that time by fresh water prawn hatcheries encouraged the entrepreneurs to go for this culture. Recent two phase post larval rearing system and segregation of juvenile prawn before stocking to grow out ponds is no doubt a tremendous achievement by the fishery scientists towards fresh water prawn farming aspects .An experimental study was conducted to compare the growth, survivality, productivity and economic aspects of M.rosenbergii culture through monoculture, polyculture (carp & prawn) in a500sq mt cemented pond P1 and earthen pondP2 at Chandrabhaga prawn Hatchery, Konark, Puri. The experiment was conducted randomly with different hazards like, heavy rain, cyclonic weather with severe wind for a period of 6 months. The average weight, productivity, growth rate were studied which revealed that growth rate was highest in all male culture, 92 kg, and in poly culture, growth of carps and prawn were also good i.e. 35kg prawn& 70kgs of carps were harvested during the experimental production. Survivality in all two types of culture was good.
