were ground to expose the core via disc grinder along the transverse plane and subsequently polished with 1000 and 2000 grit silicon carbide sandpaper to achieve a smooth surface.
Therefore, this study was conducted to evaluate the relationship between otolith
weight and observed age (calculated by reading annuli on sectioned otoliths
) in the stocks of S.
Ages determined from the use of otoliths
and scales collected from river herring were compared to quantify aging bias and precision.
To quantify otolith
[.sup.87]Sr/[.sup.86]Sr, we used a NuPlasma MC-ICPMS and Photon Machines Analyte G2 laser.
A total of 13 body landmarks and semi-landmarks, and 20 otolith
landmarks and semi-landmarks were used in our analysis (Fig.

shape used in the identification of fishes of the genus Serranus.
We are grateful to many staff and colleague for their help, particularly Russell Svec (MFM) for his interest, Zac Espinoza (MFM) for otolith
collections and Greg Bargmann (WDFW), for providing Puget Sound otolith
The Arrow Goby had a significantly longer larval duration ([F.sub.1,705] = 227.3, p < 0.0001), larger otolith
radius at settlement ([F.sub.1,705] = 28.4, p < 0.0001), and slower larval growth rates ([F.sub.1,705] =399.8, p < 0.0001) than the Tidewater Goby (Table 1).
Studies on sagittal otolith
morphometry are more numerous than descriptive studies of lapillus and asteriscus otoliths
(ASSIS, 2003; ASSIS, 2005).
The inner ear consists of three pairs of chambers, each containing an otolith
. The otolith
called lapilli occupies the utricular vestibule, the sagittae occupies the saccular and the asterisci the lagenar vestibule (Secor et al., 1991; Gomiero and Braga, 2007).
