Relation between concentration of manganese in otoliths (mean ±SE) and in 
eye lenses, scales, and spines of juvenile and adult fish (mean ±SE) collected 
from ten locations along the coast of New South Wales. 
Discussion 
Otolith elemental fingerprints are reported to be among 
the most important tools for stock discrimination for some 
species offish (Campana et al., 1995). In the current study, 
adult fish showed a significant relationship between the 
otolith elemental fingerprints and the scale and spine 
elemental fingerprints. In contrast, juvenile fish showed 
significant relationships between comparisons of otoliths 
and each of scales, spines, and eye lenses. Relationships 
among some structures were also seen for some individ- 
ual elements. There have been two other studies involving 
comparisons between elemental fingerprints of otoliths 
and other structures (Dove and Kingsford, 1998; Wells et 
al., 2000). Wells et al. (2000) compared trace elements in 
otoliths and scales of juvenile weakfish by using correla- 
tion analyses on individual elements. They found similar 
results to those in the current study, namely a significant 
correlation between Mn, Sr, or Ba in otoliths and that 
in scales. Dove and Kingsford (1998) compared elemental 
fingerprints of otoliths and eye lenses. In their study dif- 
ferences between locations were compared by using anal- 
ysis of similarity (ANOSIM) permutation tests. Where 
comparisons between locations gave the same response
