AquaVitae project (H2020) CS10 - Freshwater finfish: Hormonal induction in the pirarucu Arapaima gigas: effects in oocyte development, colour pattern and sex steroids.
Reproduction of Arapaima gigas in captivity is currently done after separation of couples in earthponds, with spawning naturally occurring during the rainy season, a method still unreliable. We tested the application of slow-release Evac GnRHa (40ug.kg-1) implants in five couples. Males and females were implanted on the 4th May (T0), on the 25th May (T23) and then at the 15th June 2021 (T44). Three couples not implanted were used as controls.
