Abstract: a comparative study on the composition of the costs and benefits from the Pacific white shrimp (litopenaeus vannamei) breeding at different density levels in water of low salinity by two farms that are doing this study, joined the co-operative group who tha Chin basin shrimp which futures contracts with the processing plant. Child farm 1 to release the white shrimp (litopenaeus vannamei) phase. Post holiday WA the density rate of 13 private farm wells 3 80000 (wells 4 acres) farm 2, release the ball, Pacific white shrimp (litopenaeus vannamei) stage post holiday WA the density rate of 10 private plantation number 100000 3 wells (wells 3 acres). The level of salinity of the water in the pond is a pond in the early experiments, each approximately 2-5 pp t. Throughout the duration of the feed for farm working to catch shrimp, 1, after a time of 129 days, found that the average weight is 0.65 +-gram 20.70 average 108.33 + 1, output-52.04 kg average survival rate of plantation and 67.02 +-5.11 percent average production cost per Rai and assigned 85000 baht.The net average 72000 baht per Rai and how best the farm at a time, after 2 106 days before catching shrimp. It was found that the productivity and survival rate on average is equal to 0.41 grams 977.78 +-+ 14.30-19.24 kg Ranch and 3.21 percent, 68.47 +-, respectively. The average cost of production per farm and 76667 baht on average a net profit of baht per Rai-45555, by comparing sales prices from the Pacific white shrimp (litopenaeus vannamei) where futures contracts with the processing plant through cooperative with Thailand at the time, the market for seafood catch shrimp. It was found that price is the Pacific white shrimp (litopenaeus vannamei) sold through cooperatives is higher than the price from the market, the sea is about 22-23 Thailand baht per kilogram. For water quality throughout the whole period of 2 farms found that appropriate levels of white shrimp (litopenaeus vannamei) As a result, this study shows that white shrimp (litopenaeus vannamei) at low density in order to produce large, shrimp should be appropriate and provide a better return for raising Pacific white shrimp (litopenaeus vannamei) with high density, but is smaller than the shrimp. The futures contracts in a way that is a member of the cooperative can reduce the risk of problems is, of course.
