| Abstract: |
| [Objective] Growth characteristics of Gracilaria lemaneiformis was studied in the sea cucumber breeding pond, and nutrient reduction efficiency of ammonium and phosphorus were determined.[Methods] From June to August,2014,in Rushan of Shandong,G. lemaneiformis was cultured with giving different conditions.[Results] The maximum weight increased from 0.7 kg to 6.1 kg, by 8.5 times factor, the SGR could reach to 5.5%. The reduction efficiency of ammonium and phosphorus were reached to 22.7% and 21.4%, respectively.[Conclusion] The results showed that G. lemaneiformis could grow well in pond under suitable condition, in addition, it uptaked effectively ammonium and phosphorus which was the suitable candidates for habitat restoration. |
