从1976年9月至1991年12月，对包括大麻哈鱼在内的5种成熟鲑科鱼类的15432只雌性进行了调查，（Oncorhynchus masou），鲑鱼（Oncorhynchus ketra），粉红鲑鱼（Oncorhynchus gorbuscha）、红鲑（Oncorhynchus nerka）、科卡尼鲑鱼（Oncorhynchus nerka）和虹鳟鱼（Oncorhynchus mykiss）的47个捕捞站位于日本本土的北海道和本州的北方部分。检查卵巢液和上皮肿瘤组织中的病毒。在调查过程中分离到三种病毒，即虹鳟病毒（OMV）、传染性造血细胞坏死病毒（IHNV）和鲑鱼病毒（CSV）。IHNV被发现在鲑鱼和马苏鲑鱼的卵巢液中，并已在7个采样地点的鱼中检测到11次。在五个案例中，这些分离物来自马苏鲑鱼。1980年，OMV首次从鄂霍次克海岸的野生马苏鲑鱼中分离出来。随后，从鲑鱼的卵巢液和上皮肿瘤组织中分离出该病毒，并发现该病毒在日本北方广泛分布。1987年，CSV从野生马苏鲑鱼的卵巢液中分离出来，并于1988年和1991年在四个地方再次分离出来。在北海道，所有的鲑鱼卵和设施都在早期出现之前用碘伏消毒，从而避免了迄今为止传染性造血细胞坏死（IHN）、OMV感染以及CSV感染的爆发，OMV被隔离的地方数量已经减少。
From September 1976 to December 1991, 15 432 females of five species of mature salmonid fishes, including masu salmon (Oncorhynchus masou), chum salmon (Oncorhynchus ketra), pink salmon (Oncorhynchus gorbuscha), sockeye salmon (Oncorhynchus nerka), kokanee salmon (Oncorhynchus nerka), and rainbow trout (Oncorhynchus mykiss) were collected from 47 catching stations located in Hokkaido and the northern part of Honshu, mainland Japan. Ovarian fluid and epithelial tumour tissues were inspected for viruses. Three viruses,Oncorhynchus masouvirus (OMV), infectious hematopoietic necrosis virus (IHNV) and chum salmon virus (CSV) were isolated during the course of this investigation. IHNV was found in the ovarian fluid of chum and masu salmon, and has been detected on 11 occasions from fish taken at seven sampling localities. In five cases these isolates came from masu salmon. In 1980, OMV was first isolated from wild masu salmon on the Okhotsk coast. Subsequently, this virus has been isolated from the ovarian fluid and epithelial tumour tissue of masu salmon and has been found to be distributed widely in the northern part of Japan. CSV was isolated from the ovarian fluids of wild masu salmon in 1987 and again isolated in 1988 and 1991 at four localities. In Hokkaido, all eggs of masu salmon and facilities had been disinfected by iodophore before the early-eyed stage, thus avoiding an outbreak of infectious hematopoietic necrosis (IHN), OMV infection and also CSV infection until now, and the number of places where OMV had been isolated has decreased.
