[quote bassrods]In every thing I have read about stunting, it happens in bodies of water 20 acres or less of water.
.On all other waters over 100 acres over harvest of the bigger fish like bass Crappie, Blue guile, Perch, will have fish of a bigger size in spring but will be smaller in average size by mid summer cause of slower growth and over harvest..[/quote]
WHAT?!
Hell, that's an easy one to bust! Just look at Lake Powell and stripers!!!
Summit Lake in Alaska -- a great case study on rainbow trout stunting -- is 130ha (~321 acres).

Cliff -- I'll throw you a bone. Here is the definition of "stunting" fish populations: [#FF0000]when fish reach sexual maturity at less than desired sizes.[/#FF0000]
It has nothing to do with forage. It has everything to do with fish reproducing, and reproducing, and reproducing to a point where growth rates slow down.
AGAIN, what you want is a population of fish in the FAST growth rate zone! You can't do this when there are too many fish.
Look at Powell. The stripers, no matter how skinny and malnourished they are, will spawn each year. They can be starving to death, literally, and yet still spawn and create more fish. This is a compounding problem! Adding more forage doesn't work when the forage bucket is already full (ie: Jordanelle). So, you MUST reduce your fish population. Not just little fish, or big fish, or medium fish: all fish!! Reduce their numbers and you will increase growth rates.
Cliff wants to talk about how fast (or slow) bass grow -- increase the growth rate to it's maximum and you will have big fish! That's the magic of fish populations and densities! Fast growth rates = big fish.
stunting is not only happening in Utah. Ask the anglers and managers about Comins Lake in Nevada. A perfect example of stunting (outside of Utah!). Mandatory catch and kill regulations on pike. No limit. Why? STUNTING!

If stunting is just a Utah thing, why does Google have so much information on stunting populations of fish??
