| 内容記述 | Undoubtedly it is very important to have any researches on the catch-fluctuations in the various types of fishery under the influence of the Solar-eclipse, but that is not the way things are now. On April 19, 1958, under the annular eclipse of the sun, some investigations were done both on the fluctuation of the Mackerel-long-line Catch and on some oceanographical conditions at the sea, 10 miles south-east off Cape Sata. In this paper some records were described about the relationships, ascertained to have existed, between the extraneous phenomena observed in the fishing-rate and the environment-factors. |

| 内容記述 | The writer made some researches on the fluctuation of mackerel long-line catch both at the solar eclipse time and before or after that time at the fishing grounds off Cape Sata. The results were summarized in Table 1~4 and Fig. 1~7. with the aid of these results the following items were ascertained. (1) The highest fishing-rate of mackerel was to be fixed at the time passed from 6~8 o'clock in the morning, it maximum being 68%. (2) The fishing-rate got under the influence of the solar eclipse showed the same ratio as that got at 6~8 o'clock in the morning. (3) It was brought into consideration that the difference in the illumination-intensity must have been one of the important factors to cause the good catch under the eclipse. (4) The body-length-distribution of Mackerel was within the range from 26~40cm, and the number of the fish measured from 31~32cm in fork-length was most numerous. (5) The water temperature and salinity appropriate for the good catch was within 14~16°C ; 34.60~34.80‰, respectively. |
