"PERTUMBUHAN TULANG LARVA IKAN NILEM (Osteochilus hasselti) YANG \r\nDITUNJANG OLEH KALSIUM TEPUNG CANGKANG KIJING LOKAL \r\n(Pilsbryoconcha exilis)"^^ . "ABSTRACK \r\nNilem carp, O. hasselti is one of the local freshwater fish species in Indonesia that has an \r\neconomical value. The purpose of this study was to obtain the optimal of calcium concentration on\r\nculture media to support vertebrae ossification, growth, and survival of nilem carp larvae. The research \r\nwas carried out from June to August 2018. The treatments consisted of 4 treatments and 3 replications. \r\nThe water hardness levels used as a treatments were A) 80 mg / L, B) 100 mg / L, C) 120 mg / L, and D)\r\n140 mg / L. The nilem carp larvae with 1 day old were used as a fish test. The fish were cultured in the \r\nfiber tanks. The density of nilem carp for each tank was 20 fish/L. fish fed Artemia and artificial diet that \r\ncontaining 38% protein. The parameter observed in this research were ossification percentage of \r\nvertebrae, absolute length growth, absolute weight growth, and survival. The observation of vertebrae \r\nossification, samples of fish were stained using Alizarin Red. The result showed that the best ossification \r\npercentage of vertebrae, absolute length growth, absolute weight growth, and survival found at C \r\ntreatment (120 mg/L of hardness) compared to the others treatments (P<0.05). Water quality such as \r\ntemperature, pH, DO during the culture were within the optimal range for nilem carp culture. Utility of\r\nshell flour from local mussel (P. exilis) is fruitful to improve vertebrae ossification, growth, and survival \r\nthat recommended of 14 mg/L CaCO3 concentration in the culture media. \r\nKey Words: Ossification, nilem carp, shell flour, local mussel"^^ .
