The studied area is Shonai and Shin river basin- hereinafter referred to as the Shonai river system. It locates about the center of Japan including Nagoya city area, 5th largest city in Japan with the population about 3millions. Therefore, two rivers flow through densely populated area and into the Pacific Ocean and are typical city-type rivers in Japan. Shin Riv. Border of basin Shonai Riv.

Report of Riverfront Research Institute No.18 ABSTRUCT September, 2007 Foundation for Riverfront Improvement and Restoration Experimental research on restoration of the gravel bed of the Makomanai River, Sapporo Hokkaido (interim report) Hiroki TAKAHASHI/Noboru MARUOKA/Kiyoshi TAKEUCHI/Keizou WATANABE The Makomanai River has many rock-bedded sections where the bedrock has been exposed as a result riverbed degradation. This is thought to have been caused by a combined effect of the narrow valley flat, soft rock, decreases in sediment supply due to the check dams constructed in the 1980s, and the fixed water route of the river due to the river improvement carried out in the 1960s. The rock-bedded river channel, lacks river structures created by gravel (sediment) transport and scour–deposition processes and does not have shallows or pools suitable as habitat for benthos and fishes. Flood control problems caused by the scouring of revetment foundations are another matter of concern. This study is underway, therefore, on technical measures to restore the gravel bed of the Makomanai River based on adaptive management approach. In this study, a series of model experiments was conducted on various structures and configurations of facilities for accelerating gravel deposition, and, according to the experiment results, possible structures and configurations of experimental facilities were narrowed down and on-site experiments were conducted. Then, after monitoring-based verification, measures to be taken to restore the gravel bed of the Makomanai -

The Behavioural Homing Response of Adult Chum Salmon Oncorhynchus Keta to Amino-Acid Profiles
Journal of Fish Biology (2016) doi:10.1111/jfb.13225, available online at wileyonlinelibrary.com The behavioural homing response of adult chum salmon Oncorhynchus keta to amino-acid profiles E. Y. Chen*†,J.B.K.Leonard‡ and H. Ueda*§‖ *Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo 060-0810, Japan, ‡Biology Department, Northern Michigan University, Marquette, MI 49855, U.S.A. and §Laboratory of Aquatic Bioresources and Ecosystems, Field Science Center for the Northern Biosphere, Hokkaido University, Sapporo 060-0809, Japan (Received 29 June 2016, Accepted 18 October 2016) Adult chum salmon Oncorhynchus keta homing behaviour in a two-choice test tank (Y-maze) was monitored using a passive integrated transponder (PIT)-tag system in response to river-specific dis- solved free amino-acid (DFAA) profiles and revealed that the majority of O. keta showed a preference for artificial natal-stream water and tended to stay in this maze arm for a longer period; natal-stream water was chosen over a nearby tributary’s water, but not when the O. keta were presented with a non-tributary water. The results demonstrate the ability of O. keta to discriminate artificial stream waters containing natural levels of DFAA. © 2016 The Fisheries Society of the British Isles Key words: artificial stream waters; dissolved free amino acids; homing behaviour; PIT tag; Y-maze. INTRODUCTION The ability of Pacific salmonids to successfully return to their natal stream follow- ing outmigration to and rearing in the ocean is a critical component of the success of the group (Groot & Margolis, 1991; Dittman et al., 1996).
