What Controls Tropical Reef Fish Populations: Recruitment Or Benthic Mortality? An Example In The Caribbean Reef Fish Haemulon Flavolineatum, M. J. Shulman, John C. Ogden

Recruitment from a planktonic larval stage has been proposed to be an important factor in limiting populations of marine organisms, particularly tropical reef fishes. We monitored recruitment and population densities of juvenile size classes In French grunt Haemulon flavolineatum (Haemulidae) from October 1978 through December 1980 In a portion of Tague Bay, St. Croix, U. S. Virgin Islands. Within our study area, 95 % of new recruits settled onto the sand and seagrass lagoon floor and within a few weeks migrated to nearby reefs; the remaining 5'10 settled directly onto reef structures. Mean annual recruitment rate was 1.8 recruits per …
