Current Research

The post-release mortality of sublegal Atlantic cod caught by recreational angling; condition and discard mortality of skates in the sea scallop dredge fishery; behavioral and blood chemical consequences of longline capture in various carcharhinid sharks in Cape Eleuthera (The Bahamas); physiological response of the yellow stingray to acute and chronic anthropogenic stressors; the effects of sample processing factors on blood gas measurements in teleosts, elasmobranchs and turtles.
