The experiments of P. orientalis culture in large and small scale have been carried out and have got a satisfactory result and an obviously economic benefit. 1. The mean body length reached 12.09 cm in intensive culture in small scale(5.3mu). A record yield of 605.45 kg per mu was obtained which is the advanced level in our country. 2. In the three test of water exchanging rate of 20%, 25% and 30%, there were no significant difference in the production and the economic benefit. So the 20% water exchanging rate per day is more economical. 3. The test of reaping by stages have had a harvest of 167.10 kg per mu. This will be of great benefit to the full usage of the equipments, the increasing of production and the improvement of the economic benefit, specially in the countryside industry. The achivement above will offer some experience to the development of the prawn industry in our country.
