| 研究内容要約 Research Summary |
川魚漁は農村の重要な蛋白源として発展してきた。石や礫の多い多摩川中流では、夏にアユ漁がよく見られた。それは投綱を使う漁で、船に乗って行う漁と、河川の中を歩きながら行う漁とがあった。 丸子橋から下流では水量も多くなり、四手綱などが登場した。そこは汽水域であるから、ボラやスズキなども狙った。さらに下流のガス橋ではアユ漁は見られなかった。 貸しボートを営業する人々は川魚漁の重要な担い手である。貸しボートは１９６０年代まで販わっていた。川魚漁や賃ポートは多摩川の汚染の影警を受けて衰退していった。 ８０年代に入り様々な対策が進み河川も浄化したが、レジャーの多様化が進み、賃ポートの客は昔ほどには回復しなかった。最近の釣プームで、多くの人が川に糸を垂れるようになった。しかし、生態系の変化で釣る魚の種類も変化している。 Fishing of fresh-water fish is highly developed, offering village residents an important source of protein. Sweetfish (ayu) fishing was quite frequently carried out in the middle Tama River , where there were abundant stones and gravels. Net casting was the main fishing method to catch sweet fish: they cast a net from a boat or by walking in the River. A large amount of water flows in the area downstream of Maruko Bridge , so four-armed scoop nets were used. Since this area is a brackish water region, Mugil cephalus [mullet] and Lateolabrax japonicus [Japanese sea bass] were also caught. Sweetfish fishing was not carried out at further downstream areas, such as Gas Bridge Boat-for-hire service played an important role in the fishing of fresh-water fish. The service was successful until the 1960’s. After that, fishing of fresh-water fish and boat-for-hire service declined owing to the impact of the pollution of the Tama River As a result of a variety of measures taken in the 1980’s, the water quality of the River improved. Even so, boat-for-hire service was less successful than in the past, because there were other various pleasures for people to enjoy. But thanks to the recent fishing boom, some people again enjoy fishing along the Tama River Fish ecology has changed, and the types of fish people can catch are different from before. |
