| 内容記述 | 病害の多い湾奥部に１試験地を設け，８月１日から９月30日まで15日間隔で５回，非罹病域の湾口部へ貝を移動避難して，感染時期の確認と罹病防止の効果を検討した。 1) 湾奥部から８月30日以前に湾口部へ移動避難したものは，湾口部に引き続きおかれていたものと同じように非常に低い罹病率（0.2～1.0%）を示したが，９月17日および30日に移動したものでは16.3%および23.8%と高い罹病率をあらわした。なお，10月上旬以降は湾奥部においても感染はみられなかったことから，この試験期間の感染期の主体は９月一杯とみてよいと考察された。 2)海底での延縄式養殖では付着物は少なく有利であるが，余り長く海底におかれていたものでは貝の成長の面に悪い影響があらわれた。 |

| 内容記述 | The present study was made with the purpose of finding effective methord for controlling the parasite penetrating into the pearl oyster. The author reported in the previous paper that the major season when pearl oysters are infected with the parasite exists during the period of about two months in the early autumn. Some groups of one unit consisting of 210 individuals which were collected as the uninfected materials at the inner part of Tanabe bay, in where the pearl oysters are liable to invasion of the parasite, were transferred into the entrance area in same bay where the infection with the parasite is free, at intervals of 15 days for five times from the 1st August to the 30th of September 1967. After that, each group was turned back again to the inner part of the bay at the time (the middle October) when the pearl oyster be going to be free from the infection such as has been reported in the previous paper. Then, on the 2nd of November, they were carried into our laboratory in Mie prefecture and were examined whether the flukes can be find or not. The results obtained are summarized as follows: 1) Three groups which were taken refuge into the entrance region befor the 30th of August showed the low infection rate (0.2~1.0%) as well as that had been set at the entrance from the first. While the two groups of the 17th and the 30th of September suffer a high infection, viz .- the former is 16.3%, the later is 23.8%, as well as that had been set at the inner part from the first. Judging from the above-mentioned fact, it can be said that the pearl oyster had not been received the infection with the parasite before the 30th of August and since the 12th of October in 1967. |
