There was no significant difference between the 
numbers of daily growth increments counted for the 
left and right otoliths (paired £-test: n= 30, P>0.05). 
Therefore, only one otolith was randomly selected for 
daily age estimation. The maximum observed age was 
242 d (for a fish at 110 mm TL), and the minimum ob¬ 
served age was 38 d (for a fish at 12 mm TL). The age 
group 58-77 d (for fish at 18-41 mm TL) was dominant 
(25.5%). Specimens of age groups 198-217 and 218-237 
were absent. The APE and CV were calculated as 4.9% 
and 3.4%, respectively. 
Sagittal otolith length, width, and radius were ob-

served in the ranges of 0.37-7.07 mm, 0.26-5.03 
mm, and 0.18-3.59 mm, respectively. Relationships 
between TL and otolith morphometric measure¬ 
ments (OL, OW, and OR) were described by linear 
equations (Table 2). 
The daily growth rate of YOY common pandora was 
estimated as 0.52 mm/d (Fig. 4). The maximum daily 
growth rate of 0.54 mm/d was found in the June co¬ 
hort, and the minimum value of 0.46 mm/d was ob¬ 
served in the August cohort (Table 3). However, there 
were no statistically significant differences in either 
slope or adjusted mean among the equations (ANCO- 
VA: .Y-1,216, df=4, P=0.305). 
Spawning of YOY common pandora took place in 
2 peaks represented by overlapping normal distribu¬ 
tions (Fig. 5). The first spawning peak was observed in
