Multi-channel feeding by migratory sharks in a fluvial-dominated estuary

Recent FSU graduate, Blake Hamilton (MSc), recently published his second paper from his Master's thesis concerning the use of river and estuarine energy sources by Apalachicola Bay sharks. His findings include:

• Stable isotope analyses revealed that coastal sharks use multiple distinct energy channels.

• Modeled shark diets indicated that, of the five species studies, 52–79% of their diet came from intermittent use of a river-dominated estuary with high fluvial input.

• Neonate and juvenile sharks exhibited a strong reliance on prey from fluvial-estuarine energy channels, gradually shifting toward nutrient sources from nearby seagrass or offshore reef habitats with age.
