The crabs in the mud samples were sorted and identified. There was a clear difference in the preference for habitat, that is, the dominant crab in sandy bottom was Pinnixia rathbuni while that in muddy bottom was Xenophthalmus pinnotheroides. However, X. pinnotheroides also drastically decreased in number during summer season when mud content and AVS-S apparently increased in 2003. Rearing experiments in a small aquarium revealed that X. pinnotheroides could endure drastic change in the environmental condition and live for long period even after releasing the metazoea. These results suggest that changes in the bottom conditions around the survey area in 2003 may have shown some adverse effects even on X. pinnotheroides. 水産大学校 National Fisheries University 2005-01-31 jpn departmental bulletin paper https://fra.repo.nii.ac.jp/records/2011790 fishu_k_53_9 https://agriknowledge.affrc.go.jp/RN/2010721505 agriknowledge AN00124678 0370-9361 水産大学校研究報告 Journal of National Fisheries University 53 1 11 9 19 https://fra.repo.nii.ac.jp/record/2011790/files/fishu_k_53_9.pdf application/pdf 563.1 KB 2024-10-11
