| Outline of Final Research Achievements |
Katsura River had high dissolved nutrients mainly from the rich forests in the catchment area. The high nutrients originated from forests were thought to contribute to high biodiversity and high biological production of fishes such as juvenile seabass and Japanese eel through diverse food web structures in the river. Forests also had function to reduce discharge of harmful small particle <30μm to river ecosystems. Local people in the study area which was recognized as the Globally Important Agricultural Heritage Systems (GIAHS) by FAO in 2013 perform a traditional fishery called Ishi-kura fishing method in estuaries. Ishi-kura is an underwater pile of approximately 0.5 tons of stones 20-30 cm in diameter and wild eels dwell inside the pile and caught using nets. We found that Ishikura plays an important cultural role which connects nature and local residents in GIAHS in addition to providing habitats for newly recruited young eels and their prey animals.
