“…data, 2009), the beginning of clear increment formation in otoliths nearly coincides with the first feeding. A similar coincidence has also been reported in Japanese anchovy Engraulis japonica [16], Japanese sardine Sardinops melanostictus [17], and marbled sole Pseudopleuronectes yokohamae [18]. We conclude that one increment was formed per day in lapillus of black-spot tuskfish until 51 DAH (Fig.…”

Otolith development and daily increment formation in laboratory-reared larval and juvenile black-spot tuskfish Choerodon schoenleinii

et al. 2009

Microstructures of lapilli were examined for reared larvae and juveniles of black-spot tuskfish Choerodon schoenleinii. Lapilli of larvae at 1 day after hatching have one diffuse and obscure ring with an otolith radius of 4.3 ± 0.50 lm (mean ± SD, N = 8). The slope and intercept of the regression between the number of days after hatching and increment counts did not differ significantly from one and zero, respectively, indicating that lapillus increments were formed on a daily basis after hatching. There was an ontogenetic shift in the relative values of somatic and otolith growth, which corresponded to the transition from pelagic larvae to settlement stage. Simultaneously, the daily increment width reached the maximum value. These findings suggest that age at maximum value of increment width can be used as an indicator of the planktonic larval duration while settlement mark is not found. Since ontogenetic shift in the relationship between otolith radius and body size was observed, backcalculation of somatic growth in black-spot tuskfish using the otolith radius during the early life stages should be analyzed with caution, and the method requires further validation.

“…However, before the otolith microstructure of wild-caught specimens is analyzed, the daily periodicity of increment formation should be validated through rearing experiments [4]. Conspicuous structures related to important events during early life history such as hatching [5,6], nutritional transition from endogenous to exogenous [7][8][9][10], extrusion for viviparous fish [11,12], metamorphosis [13], and settlement [14,15] are often inscribed on otoliths. Rearing experiments are also effective for investigating the relationship between a unique structure in the otolith and an early life history event.…”

Otolith microstructure of brown sole Pseudopleuronectes herzensteini: validation of daily ring formation and the occurrence of microstructure denoting metamorphosis

et al. 2011

Brown sole Pseudopleuronectes herzensteini larvae and juveniles were reared to validate daily otolith ring formation. At 15°C, a check (a distinct ring) formed on the sagittae and lapilli at 6 days after hatching, and clear increments regularly formed outside the check. For both otoliths, the relationship between the number of days after hatching and number of increments was linear, and the slope of the line was approximately 1; therefore, daily formation was validated. At 12°C, the check formed on the lapillus 8 days after hatching. Accessory primordia (AP) began forming on the sagittae of metamorphosing larvae, and the shape of the sagittae became complicated. AP were not formed on the lapillus; concentric rings were formed throughout larval and juvenile stages. Wide and obscure increments formed on the lapilli during metamorphosis (metamorphosing zone, MZ). Based on MZ, concentric rings that have formed on the lapilli of juveniles can be separated into larval and juvenile rings. The morphs of large juveniles' lapilli were bilaterally asymmetric, and the blind-side lapilli were most suitable for otolith microstructure analysis. This study provides fundamental information for otolith microstructure analysis in wild brown sole.

“…After lapilli were ground almost to the core with lapping film (9 µm particles), otolith images were magnified under a light microscope with translucent light (× 1000 magnification), and the number of increments was counted using an otolith measurement system (RATOC System Engineering Inc., Tokyo, Japan). See Joh et al [13] for details about otolith preparation.…”

“…For marbled sole, the onset of daily otolith increment formation occurs at the transition from endogenous to exogenous nutritional sources [13], and the timing of the first feeding is delayed several days after hatching. Therefore, in 2001-2003, the NTDDs were constructed instead of hatch-date distributions.…”
