マダイ・クロダイ幼魚の耐流性状に関する基礎的実験 A Basic Study on Rheotaxic Behaviour of Young Red Sea-bream and Black Sea-bream Yasunaga, Yoshinobu 安永, 義暢 ヤスナガ, ヨシノブ Yasunaga 安永 ヤスナガ Yoshinobu 義暢 ヨシノブ 80372019 Higano, Junya 日向野, 純也 ヒガノ, ジユンヤ Higano 日向野 ヒガノ Junya 純也 ジユンヤ metadata only access Rheotaxic behaviour of young red seabream and black seabream was studied with circulation tank of channel length was about 2 meters. Both species revealed finely rheotaxic behaviour according to increase of current velocity, but the black seabream endured more strongly to current than the red seabream. Next, rheotaxic behaviour of fish was studied in case that the reef model wsa set on the center of the channel bottom. The model produced the change of flow in the channel divided to three current velocity zone, approximate to, faster than and slower than set current velocity, and fish moved between the current variation. In comparison of behaviour of two species, it cleared that the red seabream was apt to select more finely slower current velocity zone formed in the behind of the model to current direction than the black seabream did. 水産工学研究所 National Research Institute of Fisheries Engineering 1990-03 jpn article https://fra.repo.nii.ac.jp/records/2008091 nrife_gd_12_11 https://agriknowledge.affrc.go.jp/RN/2010460285 日本農学文献記事索引(agriknowledge) AN00329681 0389-2344 水産工学研究所技報. 水産土木 Technical report of National Research Institute of Fisheries Engineering.
