抄録

Daily periodicity of otolith increment formation was validated by the use of cultured fish in order to estimate the early growth rate of wild black rockfish Sebastes cheni. Daily increments started to be deposited at extrusion both on sagittae and lapilli. Mean growth rate (0.38±0.08 mm day-1) of wild juveniles (52.2±4.8 mm in total length) collected in a seagrass Zostera marina bed in Miyagi Prefecture, Pacific coast of northern Japan, back-calculated based on the biological intercept method, was about double of those of cultured fish under similar temperatures (0.16±0.06 and 0.20±0.07 mm day-1 at 10 and 12°C).
