Mini fish formula......

i was thinking............

•When fish are born they produce a hormone that makes some of the fish in the same “family†smaller than others so I thought what if you can extract this hormone out of the water and then put it in food or make droplets or something??​

​

​

Why?​

well most of my friends that have fish often buy fish that will out grow their tanks but they say when the fish gets too big they take it back to the shop. Now if you give a fish this hormone you could -possibly-stunt its growth or just make them smaller for longer​

I would just like to know if this will work……..if so ill discuss means of extracting it from the water


egar

but would you really want to stunt its growth, isnt really fair on the fish, is it ...

Should'nt we as fishkeepers just be more responsible, I mean you wouldnt keep an Anatolian Shepherd in a one bedroom flat would you ?

 

Agreed @Relborg . why have the dog if you want to give it sleeping pills so it doesn't want to run around..?? Same with the fish, yes you'll have it to look at and it will survive. But rather don't have it if you can't keep/care for it the way nature intended..

 

The fish will die inevitably of immature organ growth. Besides that, from what the professor told me, there is no scientific proof that there even is a growth stunt hormone. Read "The Magic Water Theory" thread. He says that dominance may play a role in the growth rates of fish (Discus). More dominant fish will scare off less dominant fish during feeding resulting in the dominant fish eating more and growing faster.

He also says that strong (but not excessive) feeding may overcome this. Placing the dominant fish from one tank into a tank with bigger fish of the same species , may balance out growth.

Again, I would not advise this stunting of fish thing . . . get a bigger tank or keep another fish.

If this could be done, it would have been done by probably someone in the far east and sold as miniature "this" or "that"

 

The problem is always, you buy small fish (due to pricing), that you know will grow big, put in in your tank and it looks empty. You go and buy some more, and more, and more untill it looks good. 6 months down the line you realize that your tank is too small. You might even end with fish breeding, what now?

You WILL end with multi-tank syndrome !!! Accept it, love it and enjoy keeping fish.

I personally prefer a couple BIG fish, say 3 -7 fish in total per tank, but have never been able to control myself.... LOL

 

If you're going to buy a fish that grows big in the first place, then why would you want to stunt its growth? Pointless exercise, really. As people have explained, the stunting isn't good for the fish in the first place. An easier method would be cramming lots of big fish into small tank, as I've seen this work many times. Much cheaper, too.

If your friends buy fish that grow big for their tanks, and it happens to them more than once, I think you might need to look into mass producing a logic hormone for your friends instead. This will be much more worthwhile in the long rung.

 

hahahah +1 @SalmonAfrica

Although it may be possible to create mini species of fish, how long do you anticipate them living?

 

Wow.......................Hahahaha dont worry im not going to do it but i just wanted to know...And i assure you my friends are getting bigger tanks (i can really persway them And its only logical that the "hormone" wont stunt its growth-the only way would be to get a large amount of pure hormone and this is highly unlikly!- but might slow it down.....

But thank you so much for your imput i really appreciat it!!!!!!!!

 

Okay, lets put it this way. There is no such thing as a growth stunting hormone. If you have scientific proof then we can talk, but for now, it does not exist.

Actually there has been loads of research regarding growth hormone treatment and its been used on animals and children who have a lack of growth hormones dont know if it has been used on fish but there is the Wikipedia article: http://en.wikipedia.org/wiki/Growth_hormone_treatment

I think with today's progress in DNA and gene manipulation it would be easier to breed a species of fish and add a dwarf gene to it and make a new dwarf specie then to add hormones to the water. It will be more humane to that way the fish does not die of organ failure.

 

Anyone heard of "allelogene"(Afr.)? -chemicals that plant excrete, to avoid competitive plants to grow fast/well. Could fish have the same?

 

Need to post on first page, to go to second page...

 

Go to your User settings and change the number of posts per page. I'm still only on page one of this thread. (20 posts per page). Also... the more posts you have per page, the less downloading you are doing when loading pages all the time. You would be downloading page 1 and then page 2 if you are on 10 pages per post. I don't see why you should download the banner and all that stuff at the top just to get to the second lot of posts every time.

 

Ineresting Gert , never heard of it..I will have a look into my litrature for INTEREST sake (I strongly disagree with altering any of natures creations to suit our fads, unless done for the betterment of the species)

In my other business (buildong HDPE dams , containers etc) we have consulted on a few aquaculture products and I know of products (derived from salmon) to speed up growth, but nothing to slow it down / inhibit

 

Hi guys. Just out of interest, there is an article I read about a Discus breeder that specifically focus his breeding on size. He breeds one Discus strain only and his Discus are HUGE! Now if that is possible it should be possible to produce a line in direct contrast. So without addhng things to the water, but just selectively breeding small individuals it should eventually get you to have 'small' large fish. I'm sure there will be a limit to that though as an Oscar will not some day become a dwarf cichlid via selective breeding, . .
