Banggai Cardinalfish – Natural History, Conservation, and Culture of Pterapogon kauderni

Dr Alejandro A. Vagelli is the Director of Science and Conservation at the New Jersey Academy for Aquatic Sciences, and as adjunct professor teaches Marine Biology, Ichthyology, and Marine Conservation at Rutgers University. He is the world's leading authority on the Banggai cardinalfish, Pterapogon kauderni , and was one of the first people to breed the species successfully in captivity. He has published numerous scientific articles on its biology, ecology, and conservation, and his fieldwork in Indonesia led to the inclusion of the species in the IUCN Red List.
