more to the point that they dont appear to be
no its not okay, but the organs squishing up in the body theory is a myth. ill quote an explanation from a recent postwhen a fish's growth is slowed, because of in correct housing, the body stops growing, and so do the organs. they dont get crushed up inside, its a myth...have you ever seen a fish with swollen insides because the organs are too big for the fish?
there is no science to explain that the organs carry on growing.
so you are saying that its ok to stunt fish, if they are not effected?
as stated, "why would nature allow growth rates of the organs and skeleton to be different?"let's actually pull some info from a few actual scientific sources:
from "Development and aging of the liver and pancreas in the domestic carp, Cyprinus carpio: From embryogenesis to 15-year-old fish" by Fishelson L and Becker K in ENVIRONMENTAL BIOLOGY OF FISHES Vol 61 Issume (1) pages 85-97, 2001,
"In 15-year-old experimentally stunted fish (110-120 mm TL) the liver and pancreas resemble those of juvenile fish appearing much healthier than those of 8-10 year old large carp from commercial ponds. "
Sure, those are only a few organs and a general assumption about all the organs cannot be completely made completlely accurately, but the liver is a fairly sensiitve organ since it does a lot of the housekeeping of the fish's immune system.
Here is another from "Effect of stunting of juvenile bighead carp Aristichthys nobilis (Richardson) on compensatory growth and reproduction" by Santiago CB, Gonzal AC, Aralar EV, Arcilla RP in AQUACULTURE RESEARCH Vol 35 Issue (9) pages 836-841, JUL 23 2004:
"The carp stunted for 6, 12 and 18 months showed growth compensation, although their weights and lengths were slightly lower than those of the control fish. The body weight and length of fish stunted for 24 months were the lowest throughout the rearing period. Sexual maturation occurred only in the control fish and those stunted for 6 and 12 months. However, the onset of gonad maturity was delayed significantly (P<0.05) in males stunted for 12 months and in both groups of stunted female fish. "
Stunting delayed the development of the fish, but no mention of bulging organs or other deformities.
I believe that some of this comes from the knowledge that teleosts (bony fishes) are considered to have indeterminate growth, that is, they continue to grow over their entire lifespan. However, as some point in their lives, they devote some, and usually most of their resource intake into reproduction -- generating eggs and maturing their sexual organs. In almost every case, this results in a sigmoidal growth curve: slow at first as fry can only take in a certain amount of food, then rapid in their first year(s) as growth is dominant, then almost all resources get devoted to reproduction related activities.
Ultimately, why would nature allow the growth rates of the skeleton and the organs to be different?!?
Finally, every time I've seen one of these posts, I always ask: does anyone actually have a fish with bulging organs from stunting? I've never, ever seen a good example, and I've asked many, many times before. All I've ever seen is rumor, and "friend-of-a-friend" stories, and hearsay. Never anything actually factually presented. So, does anyone actually have a fish with bulging organs caused by stunting (and only stunting). You're probably going to have to perform a necropsy, and do it with the aid of a trained ichthyologist who will be able to identify whether an organ is larger than normal or not. I know it is a lot, but unless we have this kind of info, just the word of someone is insufficient.
in my lfs today i say a woman with 2 kids buyin a fish bowl about 3g with no fillter or evan air pump and i heard them say what they wanted to get 1 shbubkin 1 shara comet and a yellow and red goldfish so i thought i would say to her theres no fillter on the tank and the tanks not evan sutible for one of them fish let alone 4 they all need huge tanks or ponds with really good fillters and she said they only grow to the size of the tank and i said thats a load of rubbish it stunts them and kills them and she said oh well they look nice and just went ahead a brought all 4 of them some people just shouldnt be alowed to keep fish
). Despite your best efforts the mum(?) was probably pampering to the kids wants and really doesn't give a scud about the fish' health even if the hand of God pointed at her in the LFS and said "OI, WOMAN, NO".
) if I bump into them it makes for an exciting and interesting LFS visit <bonus>
My favourite LFS visit is when bumping into numerous amount of fools, giving them the word, then going about my business. I'm real fun like that.no its not fair in the fish, as stunting has been said to stop fish reaching sexual maturity and only when there growth can resume, this maturity can take place, its all a very murky subject, but whats there, shows that the fish's organs stay in proportion to the size of its skeleton.hmm interesting read, but surely stunting cant be comfortable
im sure ive seen several on the forum, loons??

hate when that happens.
