Grow to their environment...

Has an actual study been done on this hormone? I've recently read a lot
of posts leaving the "fish will grow to the size of the tank" up to
myth. I was ready to dismiss it completely too. I'd like to read about
the other side of the story. Can you post a link or the name of the
hormone?

Thanks Iain.

Yeah, I'm still looking for solid evidence of any phenomenon :/

Facts, not opinions? Newsgroups?

I'm sure you've all heard this idea before, that fish of various kinds
will
grow to fit their environment, and then stop growing.

There has been much discussion and research on the rate of fish growth.
There are several factors, which if I recall correctly, are in the
following priority : water quality, diet (total quantity, number of meals
and quality), temperature and genetics. The leading constraint is water
quality (the other factors will differ in priority based on types of fish
and opinions, but the number #1 is easily water quality). The next topic
is exactly what water parameters act to constrain growth. Here there is
still much discussion, from high nitrate levels and/or DOCs to growth
hormones released and read back by the fish. Regardless of the exact
cause, small tanks are all prone to all the suspected growth constraints,
so it does not really matter. The bottom line is that small tanks will
more obviously constrain fish growth, and the solution is to keep their
water fresh and upgrade their housing as required by their growth, imho
of course ;~).

If you have more interest in the topic, mine the newsgroup archives for
discussions. There was one in particular about 2 years ago in r.a.f.m.
which included biologists, scientists and a couple of fish-farm employees
which was quite instructive.

All species of fish have a normal size which they will grow to be around,
but when confined in small tanks their growth is slowed and stunted. In
proper sized tanks, fish should grow to their full potential size which
should not be dependent on tank size.

If their growth is stunted, they will also become more prone to disease and
may die earlier than they otherwise would.

Seems to me, you could reword this as such:

"Poor living conditions and water quality will make fish more prone to disease,
attribute to stunted growth, and possibly an early death.

You could have a look he

and see where it takes you.

Well the fish will be stunted with its growth but it will still grow.
For instance if you put an oscar in a 1 gal bowl , fed him everyday
changed the water kept great water quality he WOULD outgor that i gal
tank but be stunted in his growth.

it isnt healthy. thing sticking a child in a closet to limit their size. what runts
fish (other than genetics) is poor water quality, and that takes out their immune
system. Ingrid
