Pengaruh Umur Larva Saat Dimulainya Perendaman Dalam Hormon Tiroksin Terhadap Perkembangan, Pertumbuhan, Dan Kelangsungan Hidup Ikan Gurami (Osphronemus gouramy)

Abstract

This experiment was carried out in order to study the effect of thyroxine hormone addition at different stages of giant gouramy larvae on their development, growth, and survival rate. Treatments were conducted by dipping giant gouramy larvae at different stages (1, 5, and 1 0 days after hatching) in 0. 1 ppm thyroxine hormone solution for 24 hours. The result of this experiment showed that dipping of giant gouramy larvae at different stages in thyroxine hormone solution did not affect their development, growth, and survival rate.
