ABSTRACT

This experiment was conducted at Inland Aquaculture Research Institute liom July2003 to January 2004. Pond safety from antibiotic management was developed by usingaeration at the pond bottom and added pvc net shelter in vertical setting. Water waimanagement by microorganisms in biological fermented solution 2 hterlrai every week.After 60,000 postlarvae prawn were nursed in a 1 rai earthen pond for 2 months, small prawnwere transferred to rear in nine 400 sqm earthen ponds for 4 months with 3 stocking rates of5, 10 and 15 prawn/sqm and 3 replications.

The result of stocking rate 5 prawn/sqm. show highest production 125xO.Ikg/pond which was significant different with the others treatments. Production of the stockingrate of 10 and 15 prawn/sqm were 120t0.01 and 120+0.03 kg/pond.The stocking of 5prawn/sqm show highest not only average male weight but also average female weight of110-6418.50 and 62.03t3.10 gram, respectively. The highest survival rate was 83x.2.50 o/o tn5 prawn/sqm while survival rate of the stocking 10 and 15 prawn/sqm were 5Z4.II o/o and47tll.l2 7o, respectively. The lowest FCR was 4.14t0.05 in the stocking rate 5 prawn/sqmFCR of the stocking 10 and 15 prawn/sqm were 5.35t0.1 and 6.03t0.05, respectively bothsurvival rate and FCR show significant different among 3 stocking rates. The lowest cost ofproduction rvas 135.59 baht/tig in the stocking rate 5 praw/sq6 u,hich the cost of procluctionin the stocking rate of 10 and 15 prawn/sqm were 113.52 and 198.47 baht,&g. respecriveh,.Conclusion, 5 prawn/sqm was the optimum stocking rate compare with the other treatments.
