do you think fish growth is reduced by tank size

48 times turnover... BB loses effectiveness at anything over 4x. 2-4x for BB is recommended. No need for me to post links. Just look it up on google.
like i said earlier i think you all make good points. but the origianal question was do you think fish will grow the same size in captivity vs wild. now that being said i firmly do not believe a 5 year old arow being fed and water changed every week in a 300 gallon tank will rival the size of a 5 yr old aro in the wild. lets just say water quality is the same even though it woldnt be. imo the wild arow would be much larger then the tank raised. i have a motoro stingray in my tank which requires very good water so i do 50 percent every 5 days in a 180 but from what ive read my ray should be twice its size for its age but is not. AND MOST IMPORTANT OF ALL I HAVE WELL WATER. HAHAHAHHAHAHA. kidding but ive always had good luck with fish with well water.
How about the fact that the oscar that lives 5 years in the wild has incredible genetics, as 99% of all fish are eaten before they can reproduce.
Let's try the human analogy.
Parents, both 6' tall, have triplets. After the three children are able to survive on their own;
- one is set free outside and has ample grains to maintain health. There is a certain risk of death from the environment (e.g., lightning, homicide, etc).
- one is placed in a sealed 1,000 sq ft home. The home has sufficient fresh air blown in to maintain health. The child is given sufficient grain everyday to survive. The fresh air and grain are provided without interruption for 100 years.
- one is placed in a sealed 5,000 sq ft home. The home has sufficient fresh air blown in to maintain health. The child is given sufficient grain everyday to survive. The fresh air and grain are provided without interruption for 100 years.
If we repeat this experiment with 100 sets of triplets; I will speculate on four observations:
1 - All three would grow to about 6ft tall, assuming they lived to adulthood.
2 - On average, the children living in the homes may live longer considering the lack of risk.
3 - The size of the home will have virtually no impact on longevity.
4 - On average, those fewer people who survive outside will be in better physical shape and live longer than those who grew up in a house.
IMO - Fish raised in tanks will grow just as big because of genetics and assuming: The fresh air and grain are provided without interruption for 100 years. I suggest it is consistently providing the later that causes many people to think wild fish get larger.

The one that gets pissed off and eats the other four will grow the largest.
Im surprised that noone has mentioned growth hormones. I dont know much about this myself but I have read/heard that fish secrete growth hormones and growth inhibiting hormones. Water changes eliminate the concentration of hormones and affect growth?
Someone must know more about this than me.

Another way to dispel the fish grow to the tank size myth; partition a 6' 150G tank into a 2' and a 4' section using a tank divider. Fish will grow to the same size on both sides.
And I'm sure some of the MFK's have raised small fish that normally grow only an inch or two, larger than what you find in the wild.

Which of the kids will be living in their own waste? That is the one that will be sick all of the time and will not grow as tall or be as healthy as the others.
