A laser ablation microprobe with mass spectrometry was used to examine the variability of Sr concentration among and within scales of striped bass (Morone saxatilis). These exploratory studies demonstrated that the technique is capable of showing differences that we relate to environmental conditions. There were marked differences in scale Sr concentrations at high spatial resolution between striped bass from freshwater reservoirs in Tennessee (low Sr) and the Roanoke River – Albemarle Sound estuary system in North Carolina (high Sr). A peak in Sr concentration was found near the scale focus of striped bass collected in the freshwater Roanoke River (but not in scales from reservoir fish) that may identify saltwater parentage or estuarine rearing. In fish from the Roanoke River and Albemarle Sound, we observed spatial variations across annuli that might reflect movements between fresh and saline water. There was a typical Sr profile with depth through the estuarine scales that exhibited a peak of unresolved significance near the inside surface. Laser ablation mass spectrometry of Sr in fish scales appears to be a valuable technique for life history analyses.

We developed an integrated tagging model to estimate mortality rates and run sizes of Albemarle Sound – Roanoke River striped bass (Morone saxatilis), including (i) a multistate component for telemetered fish with a high reward external tag; (ii) tag return components for fish with a low reward external or PIT tag; and (iii) catch-at-age data. Total annual instantaneous mortality was 1.08 for resident (458–899 mm total length, TL) and 0.45 for anadromous (≥900 mm TL) individuals. Annual instantaneous natural mortality was higher for resident (0.70) than for anadromous (0.21) fish due to high summer mortality in Albemarle Sound. Natural mortality for residents was substantially higher than currently assumed for stock assessment. Monthly fishing mortality from multiple sectors (including catch-and-release) corresponded to seasonal periods of legal harvest. Run size estimates were 499 000–715 000. Results and simulation suggest increasing sample size for the multistate component increases accuracy and precision of annual estimates and low reward tags are valuable for estimating monthly fishing mortality rates among sectors. Our results suggest that integrated tagging models can produce seasonal and annual mortality estimates needed for stock assessment and management.
