Abstract
Spawning time for the reef coral Acropora aspera at reef flat Panjang Island, Central Java –Java Sea (6 ° 34’ 30” S 110 ° 37’ 45” E) was studied by laboratory observations for coral spawning from 29 Maret-24 April 2002. Gametes of most colonies were spawned simultaneously on 5 April 2002 in first quarter moon. While other colonies spawned gametes on 20 April and 24 April in third quarter moon and 4 days before full moon. All colonies spawn at 2.00-23.00, 2 hours after sunset. These results of the spawning time in the aquaria seem to be in accordance with its histological sections. Abstrak Studi waktu spawning karang Acropora aspera dari P. Panjang, Jawa Tengah (6 ° 34’ 30” LS 110 ° 37’ 45” BT) telah dilakukan melalui pengamatan di akuarium pada 29 Maret-24 April 2002. Pengamatan spawning di akuarium memperlihatkan sebagian besar koloni memijah pada 5 April yang bertepatan dengan fase lunar bulan ¼, sedangkan sebagian koloni lainnya memijah pada tanggal 20 April dan 24 April, bertepatan pada bulan ¾ hingga 4 hari menjelang bulan purnama. Seluruh koloni karang melakukan pemijahan pada jam 20.00 hingga 23.00 WIB, 2 jam setelah matahari tenggelam. Studi ini memperlihatkan adanya kesamaan waktu spawning karang A. aspera di akuarium dengan hasil pengamatan gamet pada preparat jaringan populasi karang.
