FEDDERN SEATTLE, WA November 1972 NOAA TECHNICAL REPORTS National Marine Fisheries Service, Circulars The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quan- tity and distribution of these i-esources, and to establish levels for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, develop- ment and enforcement of domestic fisheries regulations, surveillance of foreign fishing off' United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists'the fishing industry through marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyses, and publishes statistics on various phases of the industry. The NOAA Technical Report NMFS CIRC series continues a series that has been in existence since 1941. The Circulars are technical publications of general interest intended to aid conservation and management. Publica- tions that review in considerable detail and at a high technical level certain broad areas of research appear in this series. Technical papers originating in economics studies and from management investigations appear in the Circular series.

FEDDERN, Director, Marine Laboratory Precision Valve Corporation 8737 SW 132 Street Miami, Florida 33156 ABSTRACT A key illustrated by photographs and brief descriptions is presented to aid in identifying the six species of angelfishes, family Pomacanthidae, found in the western Atlantic. INTRODUCTION Fishes of the family Pomacanthidae" are dis- tinguished from those of the Chaetodontidae by the presence in the former of a large posteriorly pointing spine at the angle of the preoperculum. Worldwide, there are seven recognized genera, with three (Pomacanthus, Holacanthiis, and Centropyge) occurring in the western Atlantic. ' Contribution No. 215, National Marine Fisheries Service, Southeast Fisheries Center, Miami, Fl. 33149 and Contribution No. 1542, Rosenstiel School of Marine and Atmospheric Science, University of Miami, Miami, Fl. 33149. ' Angeliflshes have been separated under the name Pomacanthidae from the butterflyfishes (Chaetodonti- dae) by Burgess, W. (in press) on the basis of osteologi- cal and other characters. In this area, the genera are represented by six species. These have been difficult to identify be- cause of nomenclatorial changes and because of color changes from juvenile to adult. The juveniles of these species are of commer- cial importance in the marine aquarium fish hob- by, and the adults are the basis of a fishery in some parts of the Caribbean and the Antilles. The angelfishes comprise the most important group of fishes using live sponge as a source of food. An illustrated key is given for the identifica- tion of the juvenile, subadult, and adult stages of the western Atlantic species of angelfishes. Brief descriptions, common names, habitat, and distributions are also given for each species. KEY TO THE WESTERN ATLANTIC ANGELFISHES Dorsal spines 8 to 10 .B. AA. Dorsal spines 13 to 15 C. B.
