| 内容記述 | The present survey was conducted to find out the distribution ratio of useable/trash fish caught by long-line fishing. The purpose of the survey was to obtain fundamental data for examining the homeostatic ecosystem in the ocean, as an application of microcosmology. The long-line fishing was repeated 8 times in June 1980 in the East Indian Ocean by the Kagoshima Maru (1038t) of Kagoshima University. The operations were carried out by 7042 hooks, consisting of 3200 hooks with synthetic squids and 3842 hooks with frozen saury. The total number of fish caught was 166 individuals. Therefore, the fishing rate was calculated to be 2.4%. Tuna and horse mackerel were classified into the "useable fish", and shark and similar fish were shorted into the "trash fish". The distributions of useable and trash fish were estimated to be : 66.1 to 33.9% in body weight, and 54.8 to 45.2% in fish number, respectively. |
