    Cobalt nanoparticles (Co-NPs) were tested for their ability to mitigate endocrine disruption in Anabas testudineus exposed to abiotic stressors.

  • 2

    The study evaluated the effects of Co-NPs on reproductive hormones and milt quality under conditions of arsenic, ammonia, low pH, and elevated temperature.

  • 3

    Supplementation with Co-NPs at 0.4 and 0.6 mg kg-¹ significantly improved reproductive hormones and milt characteristics in fish.

  • 4

    Endocrine disruption from abiotic stressors adversely affected the hypothalamic-pituitary-gonadal axis and reproductive efficiency in fish.

    This research represents the first report on the role of dietary cobalt-based nanomaterials in enhancing reproductive performance in fish.
