Abstract

Penelitianinibertujuanuntuk menentukan suhuyang optimal untukmenentukanwaktupenetasan, dayatetastelurdan kelangsungan hidup larva ikan cupang.Penelitian menggunakan Rancangan Acak Lengkap (RAL) menurut Hanafiah (2012), yang terdiri dari 4 perlakuan dan 3 ulangan. Susunan perlakuan adalah Perlakuan A inkubasi larva padasuhu 26° C, Perlakuan B inkubasi larva padasuhu 28° C, Perlakuan C inkubasi larva padasuhu 30° C danPerlakuan D inkubasi larva padasuhu 32° C. Hasil penelitian menunjukkandengansuhu 280C berpengaruhnyataterhadapwaktupenetasan(15.39jam, dayatetas (81,64 %) dankelangsunganhidup81,11 %.Data kualitas air pendukung yaitu ; pH 6 – 7 dan DO 4,0 mg/l. "This study aims to determine the incubation temperature was good hatching time, developments embryo, hatching rate and larval survival betta fish.. This study uses a completely randomized design according Hanafiah (2012), consisting of 4 treatments and 3 replications. The composition of the treatment is treatment A larval incubation at a temperature of 26 ° C, treatment B larvae incubation at 28 ° C, C Treatment larvae incubation at 30 ° C and Treatment D larvae incubation at 32 ° C. The results showed the effect 280C temperature significant effect on hatching time (15:39 hours, hatchability (81.64%) and 81.11% survival.Water quality data supporting that; pH 6-7 and DO 4.0 mg / l."
