“…Otolith chemical composition has been a particularly valuable tool for marine and fishery ecologists in understanding the spatial ecology of marine fish (Edmonds et al, 1991(Edmonds et al, , 1992Campana and Thorrold, 2001;Thorrold et al, 2001;Gillanders, 2002;Kraus and Secor, 2005). A principal application of otolith microchemistry is to assign widely distributed adults to their natal nursery habitats using otoliths as birth certificates (Secor, 2004) or natural tags (Campana, 2000).…”

“…In our study area, there are over 400 ponds within the 100-year floodplain, and more than 200 others nearby, many of which are located on private land (Martinez 2004;Martinez and Nibbelink 2004). The advent of stable isotopic and microchemical analyses of otoliths that exploit natural markers reflecting a fish's environmental history throughout its lifetime (Campana and Thorrold 2001) provided an exciting new avenue for the study of nonnative fish sources.…”

Sources of Nonnative Centrarchids in the Upper Colorado River Revealed by Stable Isotope and Microchemical Analyses of Otoliths

et al. 2007

Nonnative fishes represent a significant impediment to the recovery of imperiled fishes, including those endemic to the Colorado River in the southwestern United States. Efforts to control nonindigenous fish abundance in the upper Colorado River basin have been unsuccessful owing in part to lack of knowledge regarding nonnative fish recruitment sources. We determined the source habitat (floodplain pond versus riverine habitats) for nonnative centrarchid fishes (largemouth bass Micropterus salmoides, green sunfish Lepomis cyanellus, bluegill L. macrochirus, and black crappie Pomoxis nigromaculatus) in the upper Colorado River using stable hydrogen isotopic composition (δD) and strontium: Calcium (Sr: Ca) ratios in fish otoliths as natural markers of environmental history. Stable hydrogen isotope analysis revealed that 59% of centrarchids exhibited the otolith core signatures expected for riverine‐origin fish, while 22% had emigrated from floodplain ponds and 19% were of uncertain origin. Strontium: Calcium ratio data were consistent with the δD assays and indicated that relatively few fish immigrated to the river from high‐salinity habitats. Black crappie was the only species that originated primarily from floodplain ponds. Efforts to control the abundance of most of the fishes included in this study should be concentrated in riverine habitats given the hydrologic conditions (below‐average river discharge) present during our study. However, the proportion of pond‐origin fish increased with fish age, which, coupled with historical river discharge data, suggested that floodplain pond contributions to riverine nonnative fish populations fluctuate with the interannual variations in flow regime and river‐pond connectivity. Our results are the first to demonstrate the utility of δD as a natural marker of fish environmental history that will probably provide valuable insights into the management of fish in other environments.

“…Natural geochemical tags in calcified structures that form during embryogenesis, including otoliths, shells and statoliths, have shown particular promise (e.g., Swearer et al 1999;Zacherl et al 2003;Becker et al 2005). Fish otoliths (earbones) have long been recognized for their utility in age estimation of fishes (Campana and Thorrold 2001), and in most species changes in the diel pattern of aragonite and protein deposition creates daily and annual increments that are apparent following proper preparation (Fowler 1995;Campana 2005). The chemistry of these increments, when combined with the chronological information that is contained within the increments, serves as a permanent archive of ambient environmental characteristics experienced by an individual (Elsdon et al 2008).…”

“…Natural geochemical signatures in otoliths have been used to assign natal origins in a number of marine fish populations (e.g., Campana et al 1994;Gillanders and Kingsford 2000;Thorrold et al 2001). Profiles of an individual's dispersal history can be derived from otolith information and subsequently used to discriminate potential source populations or locations (FitzGerald et al 2004;Sandin et al 2005;Hamilton et al 2008).…”

Otolith geochemistry does not reflect dispersal history of clownfish larvae

et al. 2010

Natural geochemical signatures in calcified structures are commonly employed to retrospectively estimate dispersal pathways of larval fish and invertebrates. However, the accuracy of the approach is generally untested due to the absence of individuals with known dispersal histories. We used genetic parentage analysis (genotyping) to divide 110 new recruits of the orange clownfish, Amphiprion percula, from Kimbe Island, Papua New Guinea, into two groups: "self-recruiters" spawned by parents on Kimbe Island and "immigrants" that had dispersed from distant reefs ( > 10km away). Analysis of daily increments in sagittal otoliths found no significant difference in PLDs or otolith growth rates between self-recruiting and immigrant larvae. We also quantified otolith Sr/Ca and Ba/Ca ratios during the larval phase using laser ablation inductively coupled plasma mass spectrometry. Again, we found no significant differences in larval profiles of either element between self-recruits and immigrants. Our results highlight the need for caution when interpreting otolith dispersal histories based on natural geochemical tags in the absence of water chemistry data or known-origin larvae with which to test the discriminatory ability of natural tags.Berumen et al.
