SharkpediaShark Fishing and Trade in Brazil with Dr. Ana MartinsThis week we are joined by Dr. Ana Martins, a postdoctoral researcher at Dalhousie University studying the shark meat trade. The shark fin and meat trade is a common media topic but angler knowledge and opinions seem to be rarely incorporated into these discussions. In her home country of Brazil, Dr. Martins utilized angler knowledge to uncover trends in the shark meat trade. Listen through the episode until the end for a rather fishy field story which will have you laughing in your seat.
The article which is the base of our discussion this week is, "Analysis o...
