Could some one explain some thing to me. I have seen time and time again people stating that when a fish's growth is stunted it's organs keep growing. Now I am confused. If some thing is stunted why would its skeleton and muscles stop growing and it internal organs continue to grow. By definition stunting is: To check the growth or development of. I do not know about any of you, but I have never seen a fish where its insides are too big for its outsides. It seams to me this would only happen with a disease. Now if a fish is stopped growing due to stunting. Then why would its insides continue to grow?
And thanks for explaining this to me.
Probably because organs grow according to hormonal triggers, meaning that even if the fish has stopped growing due to the small confines of its enclosure (the inability to use and build developing muscle, for instance, which tends to happen to koi put in shallow ponds), there's really nothing (if the water is kept clean, that is) to stop the organs from growing.
And even if they do stop growing, stunting changes the physiological makeup of internal organs, mainly the liver, which does result in premature death.
And as to our choice regarding whether or not we keep fish as pets: despite the fact that fish have kilometers of water in the wild, they don't need all that water every waking moment. They may move through it to other places, of course, but they don't actually make any use of the water a kilometer away when they are at one specific point. Fish that are properly cared for are actually better off in our tanks than in the wild. Not only would they get adequate housing (that is, a tank large enough to allow them to grow past their wild counterparts), but they also get lots of food for which they don't have to make any effort, much more protection from predators, and they lack the parasites their wild counterparts will always suffer from. Sure, the power could go out, but in the wild they could also experience an unseasonal cold snap or heat wave or algae bloom. There aren't really any extra risks, while certain other risks are removed.
