. The ecology of coral reefs : results of a Workshop on Coral Reef Ecology held by the American Society of Zoologists, Philadelphia, Pennsylvania, December 1983 . Figure of Discovery Bay, Jamaica, and adjacent fore reef showing the three sites sampled in this study. EFR = East Fore Reef; WFR = West Fore Reef. development of realistic models of reef energetics and an understanding of the behavioral and feeding strategies of many reef organisms. This study was undertaken to examine patterns of abundance and distribution among reef zooplankton at three depths on a Caribbean reef. In this study, reef zooplankton are those zooplankton [holoplanktonic, meroplanktonic, and demersal forms (Robichaux, et al., 1981)] which reside for some period in or near the reef substratum and at some time migrate at least 1 m into the water column. Most planktivory by the sessile reef community should be upon this group of zooplankton during their vertical migration. Zooplankton were collected with emergence traps in a collection program designed to answer the following questions about the quantity and predictability of zooplankton available as a potential food source for reef organisms: (1) What quantity of zooplankton is available to the reef community, especially to sessile reef-dwelling organisms? (2) How variable is the amount of zooplankton on different nights? (3) Do reef sites at different depths differ in a predictable way with respect to abundance of zooplankton? (4) Do reef sites at different depths differ in species composition of zooplankton? (5) Is there any predictable cycling of zooplankton abundance? MATERIALS AND METHODS A total of 392 zooplankton samples were collected over 29 new and full moon nights during 1976-77 using a modified version (Ohlhorst, 1980, 1982) of the demersal trap described by Porter and Porter (1977). Traps were placed prior to sunset, and collection bottles were removed the following morning. 102
