The Neotropical Ichthyological Association and the American Society of Ichthyologists will host the WILLIAM A. GOSLINE SYMPOSIUM ON NEOTROPICAL ICHTHYOLOGY during the upcoming 2003 Joint Meeting of Ichthyologists and Herpetologists, to be held in Manaus, Brazil, June 26 - July 01, 2003.

William A. Gosline was a most cherished ichthyologist, with long-standing interests in functional morphology and classification of Teleostean fishes. He is well known for his contributions to South American ichthyology, where he published on catfish and characiform systematics. His work also included marine fishes, with a primary focus on Hawaiian fishes. His life-long dedication to ichthyology was recognized by ASIH in 1996, when he was awarded the Robert H. Gibbs, Jr. Award. The Symposium will honor the memory of Bill Gosline and will also provide a focus on Neotropical Ichthyology during the first meeting of ASIH to take place in South America. The focus on Neotropical Ichthyology is quite appropriate because Bill Gosline started his professional career in Brazil, studying fish at the Brazilian National Museum.

The symposium will bring together former friends of Bill Gosline and ichthyologists interested in Neotropical Ichthyology from North and South America (and other parts of the World).
