Studi Penempelan Juvenil Karang Pocillopora Damicornis Pada Jenis Substrat Kolektor Dan Zona Terumbu Yang Berbeda Di Pulau Panjang, Kabupaten Jepara

Coral reef at Panjang Island is being gradually degraded. At least, the availability of substrates that suitable for coral\u27s attachment has a great effect to coral abundance. The aim of this research is to know coral juvenile\u27s recruitment (Pocillopora damicornis) based on the abundance of coral juvenile which attaches on the different location (zone), placement (position), type of substrate, and time of observation. This experimental research was carried out on August-November 2009 at Panjang Island, Jepara. The research uses substrate from Cement Block and Andesite Stone placed on the column and bottom of water at reef flat and reef slope zone. The result shows that coral juvenile abundance rise significantly along with time rising. Abundance of coral juvenile also different between coral zones, P.damicornis juvenile on reef flat zone is more higher (86 colonies founds), than reef slope zone (64 colonies founds). This is because the substrate in reef slope zone was far from adult coral colonies which produce planula, whereas in reef flat zone there was much found adult coral colonies

Prediksi Waktu Spawning Karang Acropora Pada Musim Peralihan Kedua Di Pulau Sambangan Kepulauan Karimunjawa Jepara

Knowledge of coral reproduction in Indonesian waters were divided into three groups, there are the spawning time which occurs in first transition season or before East season (January to April), the spawning time which occurs in second transition season or before West season (September-November), and the spawning time which occurs throughout the year. This study aims to predicted spawning time of Acropora by observe gonad maturity level during second transition season (September-October 2012) at Sambangan Island Karimunjawa Archipelago Jepara. The method used in this research was descriptive method. Distribution and composition Acropora were observed using Line Intercept Transect (LIT) method. Spawning time of Acropora was determined by presence or absence of gonad contents, and the maturity level of the gonads deferred to Hanafy et al. (2009). Gonad was examine in new moon phase, before full moon phase, and after full moon phase. The result show that distribution and composition of coral species Acropora at Sambangan Island in depth of 1-3 m was known 5 species of the stations I, 6 species at station II, and 8 species at station III with the highest cover composition at each station was a species A. formosa. Total 8 species Acropora were observe however only two species were found content of gonad. There were Acropora carduus and A. formosa. The gonad of coral A. carduus matured earlier than A. formosa. Gonad maturity of A. carduus occurred in September 2012 (new moon) and then gonad didn\u27t found in the phase before the full moon. Gonad maturity of coral A. formosa occured on the full moon phase in October 2012 and the phase after full moon the colony hadn\u27t contain gonads. Based on this information spawning of two species of Acropora likely occurred in different moon phase. Species of A. carduus has been spawned before the full moon phase and species A. formosa has been doing spawning after the full moon phase in October 2012
