Growth Inhibiting Hormone Removal

[cockroach]

Does anyone have links to some scientific literature on the removal of GIH in fish/aquaculture?
I know water changes remove thus automated changes are used everywhere.
What I am wondering is this; is there a method of removal that would be used in large/public displays where large water changes are not a viable option?

Gonadotrophin-Inhibitory Hormone in the Cichlid Fish Cichlasoma dimerus: Structure, Brain Distribution and Differential Effects on the Secretion of Gonadotrophins and Growth Hormone - PubMed

The role of gonadotrophin-inhibitory hormone (GnIH) in the inhibition of the reproductive axis has been well-established in birds and mammals. However, its role in other vertebrates, such as the teleost fish, remains controversial. In this context, the present study aimed to evaluate whether...

In some public aquariums, every time a toilet or urinal is flushed in the facility, that flush water is old water automatically taken from the system, and is replaced in the system by new water, so a constant set of water changes throughout the day.

In home aquaria, constant water changes, such as a permanent drip system may be the best way of removing hormones. I am sure there are chemical methods but some of those may have undesirable unintended effects as well.

Interesting. I did not know that. Makes perfect sense.

Activated carbon would probably remove it, but I have always been a fan of water changes instead.

I'd like to know if the carbon for sure does this. Very interesting.

This is what I am trying to establish. There are lots of probablies out there. There must also be this does and that does.

I haven't seen any write up that activated carbon can remove growth inhibiting hormones. There's fishkeeper's theories but nothing substantial from the aquaculture industry.

Hence me starting this thread. There are some seriously experienced hobbyists on here as well as people who have worked extensively with fish. Hoping they can chime in and part with the knowledge they have acquired.
