Pertumbuhan dan Tingkat Kelangsungan Hidup Transplantasi Karang Masif Favia rotundata (Veron, 2000) di Perairan Pulau Pramuka, Kepulauan Seribu, Jakarta

Abstract

Transplantation is a way of artificial coral colonies reproduction by using fragments which placed in stone, concrete, racks or net. Fragments are pieces of coral colonies taken by using a fragmentation. This research aimed to measure the survival and growth of coral transplants Favia rotundata Veron 2000. Favia rotundata placed on the composite cement module and put on a rack-sized 1 m². Recovery of coral fragment Favia rotundata wounds in six months showed that there was no cutting scars. Coloration change from pale to brownish was observed at the end of observation at the end of observation. Survival rate of transplanted fragment was 100%. The average growth rate of coral colonies during the six months study was 0.94 ±0,10 cm² (area), 0,80±0,13 cm (length) and 0,87±0,11 cm (width). The growth rate of average area was 0,0039±0,0018 cm²/month, the growth rate of average length was 0,0187±0,0094 cm/month, and growth rate of average width was 0,0228±0,0066 cm/month.
