EVALUASI PERFORMA PERTUMBUHAN DAN KELANGSUNGAN HIDUP BENIH IKAN TAMBAKAN (HELOSTOMA TEMMINCKII) PADA MEDIA PEMELIHAARAN DENGAN SUMBER AIR BERBEDA
The raising of kissing gourami (Helostoma temminckii) is influenced by various factors, with water quality being a significant one. The quality of water used in aquaculture is greatly affected by the source from which it is drawn. This study explores three different water sources: water from the local water company (PDAM), wastewater from Nile tilapia (Oreochromis niloticus) culture, and swamp water. Each of these sources has unique characteristics that may impact the growth and development of kissing gourami differently. The primary objective of this study is to evaluate the effects of water quality from various sources on the success of kissing gourami fingerlings culture and to identify the optimal water source for enhancing the growth and productivity of kissing gourami fingerlings. This research was conducted at the Aquaculture and Experimental Pond Laboratory of the Aquaculture Study Program, Department of Fisheries, Faculty of Agriculture, Universitas Sriwijaya; the Palembang Public Health Laboratory; and PT. Tambak Sejahtera Indah Perkasa Laboratory in Bangka. The research design employed was a completely randomized design (CRD) with three treatments and three replicates: P1 (PDAM water), P2 (tilapia wastewater), and P3 (swamp water). The results showed that treatment P2 (tilapia aquaculture wastewater) produced the best performance, with a survival rate of 98%, an absolute length growth of 0.79 cm, an absolute weight gain of 0.79 g, and a plankton abundance of 1260 ind L⁻¹. These values indicate that this water source effectively supported the growth of kissing gourami fingerlings.
