Respon Intensitas Cahaya Terhadap Daya Tetas Telur dan Perkembangan Larva Ikan Patin Siam (Pangasianodon Hypopthalmus. F)

This study aims to see the effect of light intensity on hatchability catfish (P. hypopthalmus. F) eggs. research was conducted in December 2021, for 30 days at Inti Karya Perdana Sijenjang Farmers Group, Jambi province. The design this a completely randomized (CRD) with 4 levels and 3 replications, treatments included: without (A), 20 watt (B), (C) 40 (D). Parameters observed included egg hatchability, hatching time, survival rate water quality. results showed that average eggs 83.00 ± 5.46 % ranged from 78.00 2.65 90.67 2.08 %. value time 19.71 2.31 hours, minutes. 85.75 4.03% 80.67 3.51 90.00 3.61%. temperature media 26.82-30.500C morning 29.50-31.830C afternoon, pH 6.65-7.76 6.23-6.78 afternoon. Dissolved oxygen 4.3-4.5 mg/L, CO2 13-15 mg/L ammonia all 0.001 mg/L. larval rearing medium during 26.93ºC-31.11 ºC 27.47ºC-31.45ºC 6.32-7.34 6.10-7. .81 dissolved 4.0-4.3 12-13 Differences form different lamp watts affect Siamese F.)
