Abstract
Taurin yaitu senyawa turunan asam amino bebas, diketahui dapat meningkatkan kematangan gonad dan kelulushidupan larva ikan laut. Taurin juga mampu meningkatkan pertumbuhan ikan tawar, namun belum diketahui respon pemberian taurin terhadap fekunditasnya. Penelitian ini bertujuan mengetahui pengaruh taurin terhadap fekunditas gurami (Osphronemus gouramy Lac.). Penelitian dilaksanakan pada bulan Januari – Maret 2015 di Desa Taman Endah, Lampung Timur, Lampung. Penelitian menggunakan Rancangan Acak Kelompok Lengkap, dengan perlakuan pakan komersil tanpa taurin (kontrol), pakan komersil ditambah taurin sebanyak 1g/1kg pakan. Ulangan berupa jumlah telur yang didapat pada setiap pengamatan. Tiga puluh delapan ekor induk ikan gurami digunakan dalam penelitian ini dengan berat rata-rata sekitar 1,2 kg/ekor. Pengamatan dilakukan selama 90 hari, dengan parameter uji berupa jumlah telur, diameter telur, derajat tetas telur, kelulushidupan larva, dan kualitas air (oksigen terlarut, pH,dan temperatur). Data diuji dengan T-student pada α >0,05 dan data kualitas air disajikan deskriptif. Hasil penelitian menunjukkan, penambahan taurin belum mampu meningkatkan fekunditas induk, namun mampu meningkatkan jumlah telur, derajat penetasan, diameter telur, dan kelulushidupan larva walau tidak menunjukkan adanya perbedaan yang nyata dibandingkan dengan pakan tanpa penambahan taurin. Katakunci : Fekunditas, gurami (Osphronemus gouramy Lac.), taurin THE ADDITION OF TAURIN SUPLEMENT TO COMMERSIAL FEED ON THE FECUNDITY OF MATURE GOURAMI (Osphronemus gouramy Lac.) Taurine is known as free amino acid has affected the gonad maturation and increased larvae survival rate of marine fishes. Taurine also affected the growth rate of fresh water fishes, however its function in fresh water fishes fecundity is still unknown. The aim of the study was to elucidate taurine effect on fresh water fishes fecundity, namely gourami (Osphronemus gouramy Lac.). The study conducted in outdoor fish pond in Desa Taman Endah, Lampung from January until March 2015. Completly random block design with was applied 2 treatments. The control group (feed without taurin) and group taurine suplement of 1g/kg commercial feed. 38 of mature gourami (average body weight of 1,2 kg) was used as experimental unit, data was colected until 90 days with parameters : egg numbers, diamaters of eggs, hatching rate, survival rate, and water quality(Disolved oxygen, pH, and Temperature). Data was analyzed using Tstudent (at 5% of significant level). After 90 days observation, the result indicated taurine has not been able to increase fecundity but able to increases the number eggs, diamaters of eggs, hatching rate, and survival rate of hatchery, yet the statistic analysis indicated no different as at α 5%. Keywords : Fecundity, gourami (Osphronemus gouramy Lac.), taurine
