Abstract

Timing of reproduction and recruitment success of the ahermatypic brooding coral, Tubastrea faulkneri, were documented over a 7 month period from September 1990 to April 1991 off Magnetic Island, Townsville. Planulae were released throughout the 7 months of the project by colonies maintained under laboratory conditions. The number of planulae released peaked in November, one week after the annual mass spawning event at Magnetic Island. Dissections of samples collected throughout the period of the project and field recruitment of T· faulkneri spat also indicated that planulae were released over a protracted eriod. Planulae were found in samples from November to February while new recruits were first seen in the field in December and continued to be recorded until April. Dissections also revealed eggs to be common in all samples throughout the study period while testes were extremely rare. High recruitment was initially achieved on settlement plates under laboratory conditions, and continued to occur after the same plates were outplanted to the field study site. Mortality declined over time, at a variable rate for each cohort. Mortality and new recruitment did not appear to be density dependent.
