Pertumbuhan Dan Kelangsungan Hidup Anak Siput Abalon Tropis Haliotis Asinina Dalam Bak Beton Pada Kepadatan Berbeda

Tropical abalones (Haliotis asinina) is a marine gastropod that has high economic value andconsumed by people in the world. In 2002, the production of abalones was 4.076 ton from totalproduction of marine fisheries in the world 8.000 ton. The countries that produce abalone byfarming are Taiwan, Cina, South Africa, Japan, Cilie, USA, Australia and New Zealand.Information about the production in Indonesia is scarce. The main issue faced by farmer ishigher mortality during post larvae and juvenile. The aim of this research was to observe theinfluence of abalone seed density in concrete tanks regarding to growth and survival. Theresearch was conducted in January - May 2012 Mataram Marine Bio Industry TechnicalImplementation Unit, LIPI. Analysis of varians showed that seed densities was not significantlydifferent (P>0.05). The highest survival rate were in density 75 individual/tank with 11.11 persenmortality. The highest growth rate were in 50 individual/tank with shell growth rate 0.21cm/14days and seed weight was 1.23 g. Jurnal Ilmu dan Teknologi Kelautan Tropis, Vol. 4, No. 2 Desember 2012. Hlm: 191-197
