Assessment of Nutrients Uptake of Ulva.P.K. Under Synthetic Environmental Conditions

Seaweed used as water purification media can remove excess nutrients from aquacultural system and provide an extra commercial crop. The uptake patterns of Ulva.P.K. to NH⁺₄ and NO^-₃ were studied under synthetic environmental conditions. Results showed that the influences of water temperature, pH value and light intensity on the uptake rate of Ulva.P.K. were different, and the three factors were also interrelated each other to removing of NH⁺₄ and NO^-₃. Control of water temperature and pH value would be important for nutrients removing by Ulva.P.K. in aquacultural system.
