摘要
为更好地预防大黄鱼感染寄生虫病,对宁德市三都澳大黄鱼网箱养殖集中的养殖区水温监测和寄生虫感染情况进行了调查研究。结果表明:2012年度,瓣体虫疫情爆发时,水温保持在23.0～27.4℃,水温低于23.0℃或高于27.4℃时,无疫情爆发。刺隐核虫疫情爆发时间和水温条件异于往年,爆发于8月末,水温维持在27.2～28.2℃;本尼登虫疫情爆发时,水温高于往年同期水平,为27.2～28.8℃,疫情最严重时水温维持在28.2～28.5℃,而随着水温降低,本尼登虫爆发程度相应降低。
In order to prevent large yellow croaker infecting with the parasite disease,the water temperature and paradise infestation in large yellow croaker culture area was surveyed in Sandu Bay, Ningde. The results showed that natural infection of Petalosoma occurred when water temperature ranged from 23.0 to 27.4℃ ,lower than 23.0℃ or higher than 27.4℃ couldn＇t occur the disease. Different from the former years,Cryptocaryon erupted in the end of August,and the water temperature was between 27.2 and 28.8℃. When Benedenia infected, the water temperature was higher than the former years,ranged from 27.2 to 28.5℃ ,and seriously when the water temperature ranged from 28.2 to 28.5℃ ,and the infestation had a downtrend with the declining of water tem- nerature.
