The role of arginine vasotocin in teleost fish osmoregulation.
The AVT system is a key component of the complex mechanism responsible for coordinating the response in teleost fish to hyper-osmotic challenge. The pituitary AVT store falls following transfer to SW from FW and this is accompanied by an increase in circulating AVT levels. This indicates that there has been release of AVT in response to this stimulus and the system is being up-regulated. The effect of an increase in secretion would appear to be predominantly to reduce GFR and urine production as is seen when AVT is injected into FW-adapted fish. This action is consistent with the requirements of hyper-osmotic challenge when water conservation becomes essential.
