Yellow Perch

[Diamondhitch]

OK lets complicate things a bit more here. How about water temp Vs. longevity and growth rate.

For example I have heard that in Texas a Walleye can reach 10 lb in as little as 5 years and seldom live past 10 years. Up here a fish that size may be 25 yrs or older. Or even a more extreme example, Lake trout, in the southern end of thier range they may be 30lb in 5 years and not live past 15 years but in the far north they may take nearly a century to reach that size!

If we keep out tanks near the upper end of a fishes prefered temp range do they grow quicker and die sooner?

That might be true Diamondhitch, it makes sense.

A perch tank would be a real cool setup though.

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.

yea i have a smallie right now and i can almost gurantee hes growing quicker in my tank than he would in the lake i got him it simply because of the constant food source

Constant food source, constant temps, and clean water=big fish really quickly lol
