| 内容記述 | The liberation of larvae in the Sea-farming, which has already taken place in the whole of Japan, is developing as a kind of important technology in the future fisheries. Accordingly, the assessment on the effect of the liberation with a wider vision should be made at this moment. The author tried to assess the effect of this on Kuruma Prawn (Penaeus japonicus) which is one of the most popular species in the Sea-farming in Japan. Two kinds of statistics, the number of released larvae and catch abundance of Kuruma Prawn from 1977 to 1980 have been used in this paper, and the author obtained three kinds of interesting results as follows: 1. Dividing the sea area around Japan into seven divisions, the most numerous liberation and catch abundance of Kuruma Prawn can be seen in the Seto Inland Sea division, and both statistical data in this division show no big changes during thefour years. On the other hand the proportional increasing tendency between the above mentioned two kinds of statistical data can be seen in the East China Sea division and the inverse proportion of them in the Middle Pacific division. 2. Looking at the statistics in each prefecture, the prefectures having no big changes in either data the number of released larvae and catch abundance of Kuruma Prawn, are comparatively numerous during the four years. The second numerous condition is prefectures having the relation as the increase in liberation and stabilityin the catch abundance. Besides, the number of prefectures which have the proportional relation between the two kinds of statistics of Kuruma Prawn is not as many as the number of prefectures which have an inversely proportional relation. 3. Comparing the two statistics in each station of the liberation, there is no relation during the four years between the increase or the decrease tendency in the number of liberations and this in catch abundance. | |||||
