KAJIAN TENTANG RESPON PERTUMBUHAN KEPITING Trapezia ferruginea YANG DITRANSPLANTASI BERSAMA KARANG Pocillopora verrucosa PADA BERBAGAI HABITAT DI TERUMBU KARANG

Abstract

There is still lack of study on Trapezia in Indonesia, even few reports on preliminary research had been done for inventarisation. The objective of this study were to analyze the growth response of the crab T. ferruginea transplanted within coral Pocillopora verrucosa in two different locations and three zones of coral reef, after 60 days of transplantation; and to determine environmental parameters that influence the growth of crab and stony coral as well. Data were analyzed by t-student and PCA. The result showed that the growth rate in weight were not different between locations, but significant (p≤0,05) between zones. The best growth rate (100%) occurred in mixing zone (sea grass and coral communities). In high sedimentation rate, the growth rate the crab greatly depend on the growth of stony coral (specifically for weight growth), locations with high temperature and total organic matter (TOM) as food source.
