Understanding the behavioral and physiological impact of ocean acidification on elasmobranches in Delaware Bay

The smooth (Mustelus canis) and spiny dogfish (Squalus acanthias) are common to Delaware Bay and coastal waters through the spring and fall, migrating to the area for pupping and foraging. Despite their abundance in research, there have been few studies done to better understand the two species in terms of their physiological responses or behavioral changes in relation to anthropogenic climate change. Relying on evolved sensory organs for food and predator detection as well as navigation, acidic water conditions could drastically affect these traits and reduce their ability to survive.  The research project is currently underway and to be supported by Delaware Sea Grant and Citi Marine Store in Doral, FL who donated a Garmin Striker 4dv to help with efforts in fish collection. Research conducting in this project will be part of Lane Johnston’s Master’s thesis and undergraduate research by Taylor Deemer.
