We tested the hypothesis that otolith (sagitta) microchemistry can document the environmental history of individual fish across an estuarine salinity gradient. Juvenile striped bass,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Morone saxatilis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(Walbaum), (80 days posthatch) were reared for 3 wk in aquaria at two temperatures and six salinities. The ratio of strontium/calcium (&lt;span class="math"&gt;&lt;span id="MathJax-Element-1-Frame" class="MathJax_SVG" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;mtext&gt;Sr&lt;/mtext&gt;&lt;mtext&gt;Ca&lt;/mtext&gt;&lt;/math&gt;"&gt;&lt;span class="MJX_Assistive_MathML"&gt;SrCa&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;) deposited in the sagittal otoliths of reared juveniles was positively related to salinity. Temperature and growth rate had relatively minor, but significant effects on the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="math"&gt;&lt;span id="MathJax-Element-2-Frame" class="MathJax_SVG" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;mtext&gt;Sr&lt;/mtext&gt;&lt;mtext&gt;Ca&lt;/mtext&gt;&lt;/math&gt;"&gt;&lt;span class="MJX_Assistive_MathML"&gt;SrCa&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;ratio. In a second experiment, juveniles (80 days posthatch) were exposed to increasing salinity (0 ppt to 25 ppt) and then decreasing salinity (25 ppt to 0 ppt) over a 20-wk period. Electron microprobe examination of the otoliths from these juveniles showed a gradual rise and decline in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="math"&gt;&lt;span id="MathJax-Element-3-Frame" class="MathJax_SVG" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;mtext&gt;Sr&lt;/mtext&gt;&lt;mtext&gt;Ca&lt;/mtext&gt;&lt;/math&gt;"&gt;&lt;span class="MJX_Assistive_MathML"&gt;SrCa&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;during the experimental period which corresponded directly with experimental changes in salinity. Field data on subadult and adult striped bass corroborated the laboratory analyses and indicated a logistic relationship between ambient salinity and otolith&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="math"&gt;&lt;span id="MathJax-Element-4-Frame" class="MathJax_SVG" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;mtext&gt;Sr&lt;/mtext&gt;&lt;mtext&gt;Ca&lt;/mtext&gt;&lt;/math&gt;"&gt;&lt;span class="MJX_Assistive_MathML"&gt;SrCa&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;ratio. Verification studies support the use of otolith microchemistry to measure migratory schedules and habitat utilization patterns in anadromous striped bass populations.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
