%X A comparative study of growth performance of giant tiger shrimp, Penaeus monodon from two traditional and two semi-intensive culture systems was conducted from 14th March to 16th July, 2008 in the village Pania under Kaligonj Upazila of Satkhira district in order to observe the following attributes: stocking density, growth, growth rate, survival rate, production, production rate, production cost, net profit, gross profit and water quality parameters. The average size of the pond in traditional and semi ¨Cintensive culture system was 3.80 hector and 0.605 hector respectively. The initial average body weight of shrimp post larvae during stocking was 0.31g and 0.305g in traditional and semi-intensive ponds. During harvest the final average body weight was found 23.95g and 31.75g respectively in traditional and semi-intensive ponds. No nursing was observed either in traditional or semi-intensive ponds. However, fertilizers and supplementary feed were used in semi-intensive culture system after stocking. The pondĄ¯s dike system was found stronger in semi-intensive ponds than traditional ponds. The average stocking density of PL in semi-intensive and traditional ponds were 117508 PL/hector and 23377 PL/hector respectively. No apparent variations of water quality parameters were observed in traditional and semi-intensive ponds through out the culture period. Throughout the culture period, the average growth rate was found 0.265 g/day and 0.2 g/day in semi-intensive and traditional culture systems respectively. The average net profit was estimated-12463.5 BDT/hector and 677814.5 BDT/hector in traditional and semi-intensive culture systems respectively. From the above study it is understood semi-intensive culture system is said to be economically, more profitable and feasible than that of the traditional culture system in terms of growth, growth rate, gross and net profit.
