Otolith Microstructore of Larval Herring (Clupea harengus): Image or Reality?

摘要: When assessed with light microscopy, daily increment formation did not appear to occur in the otoliths of known-age larval herring (Clupea harengus). Increment counts underestimated age all larvae. The age-increment discrepancy increased curvilinearly and appeared stabilize after 50–60 d. Both magnitude rate increase were consistent a hypothesis resolution-limited visibility; models otolith growth indicated that discrete increments would be resolvable microscope for first 15–20 d hatch. was also observed effects polishing, systematic difference between different-sized sagittae same larvae, other published reports apparent nondaily slow-growing pelagic Previous limited provide an empirical description phenomenon.
