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.  aArapaima gigas  aFish  aFreshwater fish  aPeixe  aPirarucu1 aBATLOUN, S. R.1 aSILVA, L. M. de J.1 aLIMA, A. F.1 aLOPES, J. T.1 aALVES, J.
