Using Otolith Elemental Composition to Track the Habitat Use, Movements, and Life History Patterns of Common Snook (Centropomus undecimalis) and Red Drum (Sciaenops ocellatus) in the Tampa Bay Estuary
Knowledge of fish habitat use and connectivity is critical for understanding the structure and dynamics of fish populations and, therefore, necessary for the implementation of successful fisheries management strategies. Tagging is an effective means of providing such information, and the elemental c...

Knowledge of fish habitat use and connectivity is critical for understanding the structure and dynamics of fish populations and, therefore, necessary for the implementation of successful fisheries management strategies. Tagging is an effective means of providing such information, and the elemental composition contained within fish otoliths is increasingly being used as a natural tag. The chemical composition of otoliths reflects the incorporation of elements from different water bodies and can thus be used to understand the habitat use, movements, and life history patterns of fishes. To assess the applicability of otolith elemental composition as a tagging technique within the Tampa Bay estuary, Florida, laser ablation-inductively coupled-plasma mass spectrometry (LA-ICP-MS) was used to analyze the elemental composition of otoliths from two estuarine-dependent fish species, Snook (Centropomus undecimalis) and Red Drum (Sciaenops ocellatus).
