海水繁養殖研究(2003~2006)-利用西刀舌浄化草蝦池水之養殖試驗
主題: 利用西刀舌浄化草蝦池水之養殖試驗
摘要:
循環利用西刀舌池水可使草蝦池水淨化,但對草蝦白斑病的抑制效果並不明顯,唯試驗池的發病有較對照池遲緩,對照池在放養第95日發現少數感染白斑病,二日後引起大量死亡。三口試驗池中的二口(S2及 S3)在第117天時發病,立即採捕,S2池有少數死亡,捕獲約433 kg活蝦,平均體重13.2 g,活存率60%,S3池已大量死亡,僅捕獲活蝦218 kg,平均體重14.1 g,活存率26%,S1試驗池與上述對照池同時發病並同樣引起大量死亡。草蝦試驗池在飼養期間內之水質(水溫、鹽度、酸鹼值、溶氧、總氨、亞硝酸)測定值均在正常適應範圍內。

標題title(英): Study on the utilizing purple clam to purify circulating water in tiger prawn, Penaeus monodon, pond
摘要abstract(英): With biological treatment of purple clam, the water qualities in tiger prawn ponds can be improved. However, the treatment delayed the infection of white spot virus syndrome (WSVD) but could not completely inhibit the happening of the disease. The infection of WSDV in control pond (S4) was found at 95th day, and then mass mortality happened after 2 days later. The same diseases were found at 117th day in treatment ponds (S2 and S3), at when we decided to harvest at once. The results of ponds after harvesting were as follows: In S2, the mean of body weight was 13.17 g and the total gain was 433 kg. The survival rate was 60%; In S3, the mean of body weight was 14.11 g and the total gain was 218 kg. The survival rate in the pond was less than that in S2, only 26%. The infection of WSDV in S1 and S4 were found at the almost same time and caused mass mortality. Water qualities such as pH, DO, ammonia-N, and NO2-N in all shrimp ponds were examined. During the experiment, all of them were in an adequate range.
