Quantifying euryhaline histories in red drum Sciaenops ocellatus : otolith chemistry and muscle isotope ratios
Abstract The combined use of otolith chemistry and tissue isotopes has the potential to reveal movements, habitat associations and food web interactions at a variety of spatial and temporal scales. Here, a combination of otolith Ba:Ca life‐history transects with muscle tissue δ 13 C and δ 15 N value...

Here, a combination of otolith Ba:Ca life‐history transects with muscle tissue δ 13 C and δ 15 N values has been used to assess habitat use and oligohaline residence in red drum Sciaenops ocellatus in subtropical estuaries in the north‐western Gulf of Mexico.

Using a mean oligohaline occupancy threshold, an estimated 82% of individuals used oligohaline waters at some point in their life.

Abstract The combined use of otolith chemistry and tissue isotopes has the potential to reveal movements, habitat associations and food web interactions at a variety of spatial and temporal scales.
