| 内容記述 | The author tried an assessment on the effect of larval release of red sea bream Pagrus major (TEMMINCK et SCHLEGEL), which has been carried out in most prefectures except Hokkaido and Northern Pacific region. Two kinds of statistics, the number of released larvae from 1977 to 1983 and the catch abundance of red sea bream from 1972 to 1983, have been used in this paper. Examinig the prefectural statistics, the author picked out five prefectures as having a positive correlation between the number of released larvae and the catch abundance, another five prefectures as having a negative correlation between the two data. Then, the comparative analysis of the two contrasting situations was done using the information on the differences such as in number of released larvae, catch abundance, location of the release/catch, fishing method, age composition of caught fish, fishing period and the fish composition at trophic level in the fishing ground of red sea bream. The results of these analyses are as follows : 1) The larger number of larvel release does not always have a beneficial effect on the catch abundance of red sea bream, comparing with the case of small number release. 2) The difference of fish composition at trophic level in the fishing ground is not so clear. 3) In conclusion, the effect of larvel release of red sea bream is not obvious and furtuer assessment shoud be made. | |||||||||||
