The aim of this study is to evaluate the development of intensive shrimp farming in land - based ponds and its production and management. This study was carried out in traditional growth ponds of the farmers in Pankep regency, South Sulawesi. There were seven ponds used for shrimp growth with intensive system such as used of high quality feed, seed, probiotic bacteria, intensive aeration, minerals and vitamine. Shrimp growth ponds used intensively culture system with profile condition as follows : (1) water depth of ponds, 120-150 cm, feeding rate four times a day, water quality parameters were measured every day for, water temperature, pH, salinity, turbidity, dissolved oxygen (DO). Average daily gain (ADG), Survival rate (SR), Feed conversion ratio (FCR) and MBW were measured every week. Stocking density every ponds was different, 49 - 56 idividuals/m2. Feeding process was conducted four times a day: 08.00 am, 10.00 am. 14.00 p.m. 16.00 p.m. Culture periods were different per ponds between 105 - 112 days. All ponds used zero water exchange system and addition water from well for change loss water by evaporation. The results of this study showed that shrimp production, 1,778 - 3,664 kg; FCR: 1.28 - 1.4; ADG : 0.22 - 0.31; MBW 21 - 23, water temperature, 29 - 34 °C; pH 7.6 - 8.6; dissolved oxygen, 2.6 - 6.1 mg/L. Salinity 13 - 22 ppt. Water depth with range, 100-130 cm, survival rate (SR) 88 - 91 % and shrimp size in the final culture period average 43 individuals/m2. In summary, Water quality parameters such DO, temperature, salinity, pH and others were in range suitable for shrimp growth and its productivity was 8,800 kg/ha. This study has benefit for shrimp growth performance, feed efficiency utilization and productivity significantly improve. © Published under licence by IOP Publishing Ltd.
