Does anyone know how big Yellow Perch get in an aquarium. I know most tropical fish are smaller in aquaria than in the wild but native fish normally go more 'dormant' under the ice in the winter and do most of their growing during the summer months. Does keeping them in prime growing conditions all year long with plenty of food help them grow bigger than in the wild? the same size? or smaller? Also do they live shorter lives when they are in warm water all year long?
 
Dunno I would like to know also though. Good question.:clap

That ideology is way out of date in thinking captive fish grow to smaller sizes than wild fish. The fact is, with advances in diet, filtration, and maintenance, that captive fish actually can grow larger than wild fish.
What was causing "stunting" earlier in the fish hobby was poor water quality. A condition known simply as brown blood disease (nitrite poisoning) causes a form of stunting through lowering the blood's ability to absorb oxygen. This condition inevitably lowers the fish's immune system and life span which yielded a visual result of attaining a smaller adult size and lethargic behaviors.
Nowadays, a multitude of species are reaching sizes far greater than their reported wild sizes. Just look at the large species being maintained in Asia, Europe, and more and more in the US. As the science of the hobby expands, our fish are living better, healthier, more long-lived lives and one of the payoffs to these advancements is watching them hit larger sizes.

Now, to answer your question...under proper conditions, yellow perch can attain a size of 15 inches. That size is attained by species living in states where ponds/lakes freeze over and in southern states that don't experience freezing temperatures.
 
i would have to say that keeping them in a tank, depending on the size of the tank, makes them bigger simply because in a fishtank the water stays the same temp. year round therfore the fish dont go dormant and can constantly grow all year
 
so basically you mean they all get to that size depending on where they are from and how they have adapted?? So if you got a fish from a palce that freezes over and put them in a warm aquarium year round, it won't work, but if you got it from a lake say in florida, then it would work right?
 
Yellow perch are all the same species, so theoretically they should all grow to about the same size, yellow perch from all over the states can grow to the same size

I would have to agree with that. My bass grew to 13" in 10 months in my aquarium. I don't think they get that big in one year in the wild here in MN.
