Keith Davis: He was protecting the oceans - then he disappeared

Keith Davis was an adventure-loving marine biologist who worked as a fisheries observer to protect the oceans. In 2015, he disappeared on the Victoria 168 tuna fishing boat owned by a Taiwanese conglomerate and hundreds of miles off the coast of Ecuador. The mystery surrounding his disappearance has brought attention to the world of commercial tuna fishing and the perilous nature of being an observer in this industry. Observers like Davis face dangerous conditions, including witnessing gun activity, knife fights, and even human trafficking incidents at sea.
