The Occurrence of Dual-gender Imposex in Japanese Freshwater Crab
TLDR
The findings reveal that imposex is not a phenomenon exclusive to mollusks and has been found to occur in a common Japanese freshwater crab, Geothelphusa dehaani, which inhabits TBT-uncontaminated mountain streams in Japan. Expand
Acid – Base Balance of Hemolymph in Pacific oyster Crassostrea gigas in Normoxic Conditions
We examined hemolymph O2 partial pressure (Po2), pH, total CO2 content (Tco2), CO2 partial pressure (Pco2), and bicarbonate concentration ([HCO3–]) in order to evaluate the ability of the acid–baseExpand
Age and growth of the torrent catfish Liobagrus reinii in the Kawahara River of the Chikugo River system, Kyushu Island, Japan
Age and growth of the torrent catfish Liobagrus reinii from the Kawahara River in the Chikugo River system, Kyushu Island, Japan were studied by examination of the vertebral centrum. A total of 289Expand
Age and Growth of the Bagrid Catfish Pseudobagrus nudiceps in the Koya River, Western Honshu Island, Japan
Age and growth of the bagrid fish Pseudobagrus nudiceps in the Koya River, western Honshu Island, Japan were studied by examining ring marks of the vertebral centrum. A total of 212 males and 155Expand
Structure and Artificial Baits for Cage Traps to Capture Freshwater Palaemonid Shrimps
TLDR
The results of field experiments demonstrated that the shrimp trap with the entrance size of 40mm and bait 1 can be effective to capture not only the palaemonid shrimps but other freshwaterShrimps and crayfish. Expand

Survival rate of Japanese mitten crabs, Eriocheir japonica, falling from a simulated dam onto concrete and into a pool
降河中のモクズガニが,堰堤から安全に落下できる条件を明らかにするために実験を行った。甲幅約 5 cm の個体がコンクリートに落下する場合,落差 1 m で歩脚が損傷する個体が出現したが,その後 15 日間の飼育で 10 個体すべて生残した。落差 2 m 以上では死亡する個体が現れ,落差 5 m 以上では全 80 個体が死亡した。落差 11 m から水深 60 cmExpand
Effect of Air Exposure on Acid–Base Balance of Hemolymph in Hard-shelled Mussel Mytilus coruscus
We investigated the hemolymph acid–base status of the hard-shelled mussel Mytilus coruscus exposed to air for 24–48 h at 24°C. M. coruscus exposed to air showed a decrease in hemolymph pH from 7.625Expand
