"石斑魚為亞洲多國重要的高經濟價值海水養殖魚類，但是近年來養殖石斑魚苗常在培育過程中傳出因病毒的感染而造成大量死亡的疫情，使魚苗培育業者損失慘重，而台灣石斑虹彩病毒正是目前嚴重威脅本省海水魚養殖的兩種魚類病毒之一。由於多種水產生物遭受病毒感染後，殘存者可能成為帶原者(Carrier)繼續經由水平或垂直方式傳播病原，當環境不良時再次爆發疾病引起死亡，因此，為了有效防治虹彩病毒的傳播，本計畫擬追蹤調查虹彩病毒在石斑種魚中的感染情形，同時監控所孵化出之幼魚罹病情形和活存率，此外配合所研發出之石斑虹彩病毒不活化奈米疫苗的施用，以期能培育出健康種苗。如此除了可以提高石斑魚育苗過程之活存率，並可降低生產成本，使本省的魚苗在國際市場上更具競爭力。" "Grouper (Epinephelus spp.) is an important and high-priced maricultured finfish in several Asian countries. However, outbreaks of viral disease, such as iridoviral infection have plagued larvae and juvenile groupers in the past few years. Grouper iridovirus of Taiwan (TGIV) is highly pathogenic and have been shown to cause severe economic losses in maricultured fish species in this island. There is evidence that survival of viral infection could become carrier in populations and shed virus via vertical or horizontal transmission. Afterwards, further stress due to adverse environmental conditions will result in the onset of disease from time to time. For this reason, attempts were made to clarify the prevalence of iridoviral infection in brood grouper first. Subsequently, tracing infection of individual brooder and survival of offspring will provide useful information for disease control strategy. Thus, effective protection against iridovirus will be expected to achieve by eliminating of the carrier state and vaccination strategies."
