| 内容記述 | According to the conventional planning guideline, when fish shoal around an artificial reef is investigated using a fish finder, it is stipulated that data should be collected in the 8 radiating directions from the artificial reef. However, steering a boat in such a way is difficult in actual sea areas with strong wind or ocean current. In addition, it is difficult to estimate whole fish quantity from such radiating survey data. When there are finely divided grid data, grasping whole fish quantity is easy by integrating these data. Even though a program software to convert random data to plane field data has appeared recently, when information volume is relatively large such as fish finding data, an apparatus with large amount of recording capacity is required. The authors have established a new technique to input the data from a fish detector with a portable D-GPS to a note-type personal computer, and easily obtain grid data even on the sea using a system composing of a program language attached to a commercially available spread sheet software. The verification of the operation was carried out using the research boat "Takamaru" of our laboratory. The mobility a middle-sized research boat possesses, advanced electronic equipment of "Takamaru," and excellent steering technique have greatly contributed to the success in the verification work. | |||||
