Strontium. None of the three fish species
exhibited a significant HabType*TL interaction
for strontium (data not shown). Moreover, strontium
concentrations were not significantly associated
with TL in kelp bass (data not shown) and
kelp rockfish (data not shown). In kelp bass, strontium
concentrations did not differ significantly
between HabTypes (Figure 22). However, in kelp
rockfish, strontium concentrations differed significantly
between HabTypes (Figure 22), with lower
concentrations occurring in fish from oil platforms
(mean, 120. µg/g; 95% confidence interval,
92.-150. µg/g) than from natural areas (mean, 200.
µg/g; 95% confidence interval, 160.-260. µg/g). In
Pacific sanddab, a significant inverse association
was found between strontium concentrations and
TL (F 1,94.6
=11.30, P=0.001). On average, strontium
concentrations in Pacific sanddab decreased by
3.8% (95% confidence interval, -5.9% to -1.6%)
for every 1.0-cm increase in TL. Nevertheless, after
controlling for TL, strontium concentrations
in Pacific sanddab did not differ significantly between
HabTypes (Figure 22).
Tin. Kelp bass did not exhibit a significant
HabType*TL interaction for tin (data not
shown). Moreover, in kelp bass, TL was not
significantly associated with tin concentrations
(data not shown). On average, tin concentrations
in kelp bass did not vary between Hab-
Types (Figure 23). By comparison, tin concentrations
in kelp rockfish and Pacific sanddab
exhibited significant HabType*TL interaction
effects (Figures 24-25), and significant associations
with TL (for kelp rockfish, F 1, 53.6
