The mean value of m is mean = 0.0078 ±0.002 (n = 30, total length = 17.0-24.8 cm) for C. sordidus and 0.0067+
0.004 (n = 30, total length = 17.0-36.8 cm) for H. harid (b = 0.0027, a = -0.0473). The relationship between otolith
mass and fish total length is m = a l + b, (b = 0.0027, a = -0.0473) for C. sordidus and (b = - 0.0024, a = -0.0698)
are shown in Figure 2 and Figure 3.

The mean absolute value of the otolith mass asymmetry |x| for C. sordidus and for H. harid are 0.44 and 0.03
respectively.
The regression analysis has shown that the fish length and |x| were not related in the two-species studied (Figure 4
and Figure 5). However, the qualitative results of absolute value of otolith mass difference |mR– mL| in both
species showed to be increased slightly with the fish length (Figures 6 and Figure 7).
