摘要:【目的】研究龙须菜(Gracilaria lemaneiformis)在海参养殖池塘中的生长特性及其对水体中氨氮和活性磷的去除作用。【方法】2014年6~8月,在山东乳山海参养殖池塘试验养殖龙须菜,设置不同养殖深度和养殖方法,共养殖80 d。【结果】龙须菜最大增重从0.7 kg到6.1 kg,增长8.5倍,其SGR可达5.5%;水体氨氮平均下降22.7%,活性磷下降21.4%。【结论】龙须菜可以在适合的池塘中养殖,并且能有效去除水体中的氨氮和活性磷,是有效的近海生境修复海藻。

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.
