“…Otolith Cu seems subject to an ontogenetic pattern in some fishes (Hüssy et al, 2016). In flounders and gadoids, both Zn and Ca tend to be markedly elevated in the core region (Jackman et al, 2016;K. Limburg, M. Samson, unpublished obs.…”

A consistent temperature response was not evident across studies for either environmental or physiological tracers, presumably attributable to variable relationships between temperature and fish behavior and physiology (e.g., feeding rate, reproduction). Biomineralization thus has a controlling effect on otolith element concentrations for elements that are linked with somatic growth, but not for elements that substitute for Ca in the crystal lattice. Interpretation of the ecological significance of patterns from field samples therefore needs to consider the impact of the underlying biomineralization processes of the element in question as well as physiological processes regulating the availability of ions for inclusion in the growing crystal lattice. Such understanding will enhance the utility of this technique to address fisheries management questions.

“…Equivalent chemistry of most bony fish sagittae appears to be the result of selective pressure to maintain morphological symmetry of the vestibular system. Conversely, flatfish (Order: Pleuronectiformes) sagittae, which exhibit asymmetry in mass (Loher et al ., ; Morat et al ., ; Kajajian et al ., ) and morphology (Jackman et al ., ), do not appear to be chemically equivalent (Loher et al ., ; Morat et al ., ; Kajajian et al ., ; Jackman et al ., ). With such a strong correlation between growth pattern and chemical equivalency, the observed equivalency among C. limbatus vertebrae from different regions of the vertebral column is somewhat of a surprise.…”

Key methodological assumptions regarding the degree of natural variability and influence of sample handling and storage of elasmobranch vertebral chemistry were assessed using laser-ablation inductively coupled plasma mass spectrometry. Vertebral chemistry of juvenile blacktip sharks Carcharhinus limbatus was examined to identify whether differences existed among different regions of the vertebral column, between thoracic vertebrae of individual fish or within individual vertebrae. Additionally, the effects of bleach exposure and storage in ethanol on vertebral chemistry were compared. No significant variation in vertebral chemistry was found among different regions of the vertebral column or between thoracic vertebrae, but significant differences among transect locations within individual vertebrae were observed. The variation at all three levels appears comparable with published data on sagittal otoliths of bilaterally symmetrical teleost fishes. The experimental assessment of potential treatment effects indicated vertebral chemistry was not significantly affected by bleach or exposure to ethanol. Taken together, these results support the idea that vertebrae taken from the same region of the vertebral column can be treated as equivalent and at least certain elements remain robust to exposure to bleach and ethanol.

“…Elements were selected for analysis based on their potential use as indicators of oil (e.g., V and Ni; [ 42 ]) or pollution (e.g., Cu, Pb from terrestrial sources; [ 43 ]) exposure. The list also included elements traditionally used as environmental indicators of temperature and salinity, such as Sr and Ba [ 44 , 45 ], and sediment redox (Mn; [ 46 ]). Calcium was used as a universal internal standard to account for the amount of otolith material ablated.…”

Is Exposure to Macondo Oil Reflected in the Otolith Chemistry of Marsh-Resident Fish?

et al. 2016

Genomic and physiological responses in Gulf killifish (Fundulus grandis) in the northern Gulf of Mexico have confirmed oil exposure of resident marsh fish following the Macondo blowout in 2010. Using these same fish, we evaluated otolith microchemistry as a method for assessing oil exposure history. Laser-ablation inductively-coupled-plasma mass spectrometry was used to analyze the chemical composition of sagittal otoliths to assess whether a trace metal signature could be detected in the otoliths of F. grandis collected from a Macondo-oil impacted site in 2010, post-spill relative to pre-spill, as well as versus fish from areas not impacted by the spill. We found no evidence of increased concentrations of two elements associated with oil contamination (nickel and vanadium) in F. grandis otoliths regardless of Macondo oil exposure history. One potential explanation for this is that Macondo oil is relatively depleted of those metals compared to other crude oils globally. During and after the spill, however, elevated levels of barium, lead, and to a lesser degree, copper were detected in killifish otoliths at the oil-impacted collection site in coastal Louisiana. This may reflect oil contact or other environmental perturbations that occurred concomitant with oiling. For example, increases in barium in otoliths from oil-exposed fish followed (temporally) freshwater diversions in Louisiana in 2010. This implicates (but does not conclusively demonstrate) freshwater diversions from the Mississippi River (with previously recorded higher concentrations of lead and copper), designed to halt the ingress of oil, as a mechanism for elevated elemental uptake in otoliths of Louisiana marsh fishes. These results highlight the potentially complex and indirect effects of the Macondo oil spill and human responses to it on Gulf of Mexico ecosystems, and emphasize the need to consider the multiple stressors acting simultaneously on inshore fish communities.
