Abstract: Slow growth is obstacles to achieving the target of goldfish production (Carassius auratus auratus). The process of metabolism and growth in fish is influenced by hormonal factors. This research was conducted in February-March 2016 at Hatchery and Aquaculture Technology Laboratory Aquaculture Study Program of Faculty of Agriculture University of Malikussaleh. This study aims to examine the effect of thyroxine (T4) and hormone recombinant Growth Hormone (rGH) hormone by immersion method with different doses on growth and survival of goldfish larvae. The experimental method using a complete non factorial randomized design with four three replication treatments. The treatment is: A= control, B= T4 0.05 mgL-1 + rGH 5 mgL-1, C= T4 0.1 mgL-1 + rGH 10 mgL-1, D = T4 0.15 mgL-1 + rGH 15 mgL-1. Result of research with giving of recombination of hormone T4 and hormone rGH with different dose have an effect on to decrease of yolk volume, egg yolk absorption rate, growth and survival with p value
