Many kinds of fish are the target of fishing. Commonly the fishing method is different according to the kind of fish. The fishing methods depend fundamentally as the habit of fish. Further, the fishing methods are considered by synthesizing requirements, such as place, tide, fishing tackle, and seasons. For this reason, although there are about 30 kinds of fishing now, these are mixed together to make mamy other fishing methods. The fewer one is good although these numbers are a few compared with about 100 of the number of target fish. In the book of fishing, the operation of fishing talks only about the fish classification and there is no explanation of the operation as a whole. So, we analyzed the fishing methods of freshwater fish, which broke down into basic operation guideline. On the basic of these, this paper reports about the fishing methods classified newly by the unified standard.
