My guest today is Dr. Karlisa Callwood. Dr. Callwood is the director of the community conservation education and action program for the Perry Institute for Marine Science, and an expert on the coral reef fisheries of the Bahamas, and has a PhD in Ecosystem Science and Policy from the University of Miami in Florida.Today we talk about about the coral reef systems of the Bahamas, how they function, their overall health, and a couple important species that call the reefs home - spiny lobster (Panulirus argus) and parrot fish.In fact, Dr. Callwood's research and expertise goes well beyond these animals and their ecology, and into the social and cultural impacts of policy and fishing at the reefs. Dr. Callwood tells us how an emerging Parrotfish fishery adds new pressures to the coral ecosystem. And how the spiny lobster fishery, driven partly by few regulations for Bahamian citizens, has evolved to include new forms of fishing that are more productive for the fishers, but also put fishers in conflict with each other. And these new methods have unknown long term ecological impacts, as Dr. Callwood explains.As you'll hear, Dr. Callwood combines ecological knowledge with building trusting relationships with the people on the islands, allowing her to deeply understand the motivations and rationale of the fishers. This understanding allows her to assess and recommend policy responses that strike a balance between reef health and the needs and motivations of the people on the islands.You can find Dr. Callwood on twitter @Sci_in_Color and instagram @science_in_color.It's a fascinating set of topics today - please enjoy!FULL SHOW NOTESSupport the show
