There were fewer vertebrae (Mean ± SD) in hatchery-reared- (52.5 ± 2.15) than in wild fish (53.7 ± 0.92). For both the hatchery-reared- and the wild individuals, the correlations between number of vertebrae and vertebral column length (VCL) per standard length (SL) were positive. Head length (HL) was approximated as SL minus VCL. Therefore, the proportion of HL in relation to SL became lower with the higher number of vertebrae. Their vertebral number may relate to the difference of body proportions between hatchery-reared- and wild fish.the Societas Scientiarum Stetinensis (Scientific Society of Szczecin)2013engjournal articleVoRhttp://hdl.handle.net/2115/74031https://doi.org/10.3750/AIP2013.43.1.110137-1592Acta ichthyologica et piscatoria : an international journal for ichthyology and fisheries4317577https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/74031/1/Nakaya%20et%20al%20ACTA%2043.pdfapplication/pdf1.81 MB2013
