[Shimanto City, Kochi Prefecture] Savoring the River! Ayu, Unagi, River Shrimp, Gori! Traditional Fishing Methods That Live Alongside the Shimanto River
Introducing the traditional river fishing methods passed down by river fishers on the Shimanto River. This highlights the important local culture of living close to the river and gratefully receiving its bounty.
〇Traditional Fishing Methods of the Shimanto River
The Shimanto River’s traditional fishing methods have been carefully preserved by local river fishers. While their form has gradually changed with environmental shifts, they still remain part of daily life. The river’s abundant gifts—ayu (sweetfish), unagi (eel), tenaga-ebi (long-arm shrimp), and aosa nori (green seaweed)—brighten family meals with the seasons. Skilled chefs in Shimanto City also prepare them into delicious dishes for visitors, and various processed forms are enjoyed as souvenirs.
〇See the River, Taste the River
A slow walk along the Shimanto River reveals traps for catching eels and long-arm shrimp seen from chinkabashi bridges, partly submerged in the water. Depending on the season, you may encounter people fishing for ayu or working from traditional river boats. Along the banks you might spot stone-lined devices for catching gori, and at the river mouth workers harvesting green seaweed. If you look closely at the Shimanto River, you’ll discover human lives intertwined with the river. In the evening, taste the very ingredients caught with the traps you saw, slowly savored at a local restaurant. It’s a distinctive, insider way to enjoy the Shimanto River.
〇Introduction to Traditional Fishing Methods
・Ayu Fire-Swinging Fishing
Nets are set across the river in advance, and at night a boat swings torches from the deck. Startled by the dancing bands of flame, ayu panic and are driven into the nets. Today this practice often uses LED lights, but the principle remains the same as the traditional method. Ayu are also caught by cast nets, angling, and other methods.
・Long-Arm Shrimp Fishing
From a chinkabashi bridge looking toward the water’s edge, you can see PVC pipes spaced at regular intervals. These are korobashi, traps for catching long-arm shrimp. Once made of wood, they have changed to more convenient materials over time. Long-arm shrimp are commonly enjoyed deep-fried whole, producing vibrant colors, and are treasured as a local flavor—some grow large enough to resemble cucumbers.
・Unagi (Eel) Fishing
You may see pieces of styrofoam or PET bottles floating in the river without drifting away; they can mark korobashi used to catch eels. Sensitive to smell, eels avoid resin traps, so wooden korobashi are still widely used.
・Gori Fishing
If stones are lined along the riverbank to dam the water, they may form the setup for gori’s noborio-toshi-ue fishing. In the Shimanto River, juvenile Numachichibu fish are called gori and are enjoyed as a spring to early-summer delicacy. They are typically eaten deep-fried or simmered in soy-based preserves.
