TINGKAT KEBERHASILAN HIDUP TRANSPLANTASI KARANG Porites sp. PADA SUBSTRAT RUBBLE SKALA LABORATORIUM

Abstract

Porites sp. can be found scattered on the island of Madura. This study aims to determine the survival rate of coral Porites sp. by transplantation using rubble media on a laboratory scale. The transplanted coral samples came from Ten Waters, Bangkalan. The transplanted coral fragments range in size from 3-5cm. The success rate of coral life was 100% for 9 weeks, length growth for 9 weeks was 0.0733 cm with an average growth of 0.0067 cm/week. Air quality is an important factor in supporting the survival rate of transplanted corals on a laboratory scale. The air quality must be in accordance with the coral's original habitat so that the transplanted corals can live well. Air quality observed in the form of temperature 33 ̊C, Salinity 25-40‰, pH 6.5-7.5 and DO >5. In addition to air quality, an important factor in coral transplantation is the choice of substrate. The substrate debris in this study showed good results for coral transplantation.
