Question

Osmo regulation in fish is controlled by adrenalin

Answer 1

Osmoregulation is the process of maintaining an internal balance of salt and water in a fish’s body.The neuroendocrine system is a critical part of osmoregulatory adaptations. Cortisol has been viewed as ‘

the seawater-adapting hormone in fish and prolactin as ‘the’ fresh water adapting hormone.

So hormones control osmoregulation
