This week Alanna chats with Dr. John Mohan, a Conservation Biologist in Protected Resources at the North Carolina Division of Marine Fisheries, about his work using chemical tracers such as trace elements and isotopes in fisheries science. The two chemistry fans talk about applications in species such as striped bass, Atlantic croakers, Pacific bluefin tuna, and a variety of sharks. John provides a crash course in chemical tracers for those interested in using these tools, and gives excellent advice for scientists of all stages.

Main point: "Go with the flow"
