By experiment device and way designed, on the conditions of artificially simulated water enviroment, the experiments have been done with 100 young Penaeus japonious per group on the their adaptability to illuminance, temperature, salinity, dissolved oxygen, pH, along with double factors of temperature and salinity, temperature and dissolved oxygen. By analyzing the data of the experiments, the paper discovers that they are very drawn to light, their suitable range is 133 - 10631x. Their bearable temperature range is extensive , the suitable range is 21 - 29℃ ,the most is 25 - 28℃. Their bearable salinity range is extensive, the suitable range is 18- 30,the most is 18- 22. Their bearable dissolved oxygen density range is no less than 6.4mL·L-1. Their bearable pH range is 7.7 - 8.8, the suitable range is 7.7 - 8.6, the most is 8.0 - 8.2. While analyzing the data of the experiments, the results show that temperature effect is the most remarkable, the effect of salinity and dissolved oxygen is subordinate.
