“…Researchers have primarily used Sr : Ca (Secor et al 1995;Fablet et al 2007;Hedger et al 2008) and, to a lesser extent, Ba : Ca (Elsdon and Gillanders 2005a;Hamer et al 2006) ratios, to reconstruct environmental histories of fish based on the relationships that they form with salinity. We found that the relationship between salinity and either Sr : Ca or Ba : Ca was not simple, and therefore it is difficult to use these simple single-element relationships to reconstruct environmental histories of hardyhead in the Coorong.…”

“…Fish migrate in order to optimize life-history stages that may require specific environments, or to take advantage of a condition offered by the different water type and/or habitat, such as increased food resources or shelter (Limburg 2001;Secor et al 2001). Traditional approaches to determining fish movement have involved conventional tags (e.g., dart tags) or, more recently, acoustic and radio tags.…”

We investigated the effect of hypersaline conditions on the water chemistry of the Coorong Lagoon, the terminal estuary of Australia's largest river, and the otolith chemistry of a common fish within the system. Water samples and fish were collected from 10 sites along the Coorong, ranging in salinity from 5.8 to 123.4, on six occasions over 14 months. Water (Ca, Ba, Mg, Mn, and Sr) and otolith (Ba : Ca, Sr : Ca, Mg : Ca, Mn : Ca, Na : Ca, Li : Ca, d 13 C, and d 18 O) concentrations were measured. Water Sr, Mg, and Ca concentrations exhibited conservative behavior (i.e., concentrations increased with salinity). Water Ba concentration decreased from nearfreshwater to marine salinities followed by an increase from marine to hypersaline waters, a pattern not previously reported in the literature. Three of the six otolith element : Ca ratios and d 18 O showed significant linear correlations with salinity, but the best fit model for Ba : Ca was a segmented regression with a breakpoint. Positive linear correlations were also found between otolith Ba : Ca and water Ba : Ca, as well as otolith Mg : Ca and water Mg : Ca. Results have implications for reconstructing past salinities inhabited by fish, because they imply that several elemental and isotopic ratios will be necessary to determine whether fish have inhabited, or been exposed to, hypersaline environments.

“…Previous research on northern stocks of Striped Bass has provided evidence for diverse lifetime migration patterns: some members of a given population reside in freshwater or estuarine environments throughout their life (resident contingent) and others are more exploratory and engage in large-scale coastal migrations (migratory contingent) (Clark, 1968;Secor, 1999). There is particularly strong evidence for this "contingent" behavior in Striped Bass in the Hudson River (Secor and Piccoli, 1996;Secor et al, 2001;Zlokovitz et al, 2003). Our study, however, provides little indication of this phenomenon in the AR stock of Striped Bass.…”

Abstract-We analyzed tag returns from a long-term tagging program to evaluate the movement patterns of the Albemarle Sound-Roanoke River (AR) stock of Striped Bass (Morone saxatilis) during a period of stock recovery in 1991-2008. The AR stock was found to increase its movement outside the Albemarle Sound estuary (from <4% to 15-31%) as it recovered from 1991 to 2008. Analysis with multinomial logistic regression where recapture area was modeled as a function of fish size and stock abundance indicated that Striped Bass from the AR stock exhibit a strong size-dependent emigration pattern. Larger (older) adults >600 mm in total length (TL) were much more likely to emigrate to ocean habitats (after spawning) than were smaller adults (350-600 mm TL), which mostly remained in inshore estuarine habitats. Smaller adults showed evidence of density-dependent movement and were recaptured only in adjacent estuarine systems, the Pamlico Sound and lower Chesapeake Bay, during periods of increased stock abundance. Assessment and management strategies for the AR stock of Striped Bass could be improved by accounting for movement (and hence harvest) outside the currently assumed stock boundary. More broadly, this study illustrates that changes in the demographics, such as size structure and total abundance, within fish populations can result in major shifts in their distribution and that long-term tagging data are useful in detection of such population-level changes in movement patterns.

“…Our use-groups were similar to spawning and migratory contingents (Clark 1968;Secor et al 2001) originally defined by Clark (1968) as a unique group of striped bass that ''engage in a common pattern of seasonal migrations between feeding areas, wintering areas, and spawning areas.'' Within contingents, migratory shifts occur, suggesting that these designations need not remain static over the life of the fish (Wingate and Secor 2007).…”

Abstract.-Using acoustic telemetry on migratory striped bass Morone saxatilis in Plum Island Estuary (PIE), Massachusetts, we found that striped bass (335-634 mm total length) tagged in the spring and summer Striped bass spent the most time in two specific reaches: middle Plum Island Sound and lower Rowley River. In both years, three different use-groups of striped bass were observed in PIE. Short-term visitors (n ¼ 24) stayed in the estuary only briefly (range ¼ 5-20 d). Two groups of seasonal residents stayed for more than 30 d, either in the Rowley River (n ¼ 14) or in Plum Island Sound (n ¼ 22). Within PIE, the two seasonal-resident use-groups may be foraging contingents that learn how to feed efficiently in specific parts of the estuary. These distinct within-estuary use patterns could have different implications for striped bass condition and prey impact.
