Fyfer, what's making the fish appear so reddish? It could be the natural colour of the fish under the water and it might be exaggerated by the camera. They do tend to look like that underwater. They are brown trout so they have a natural red and brown colour.

I would caution that long term stunted populations select for small size in many species. It is a survival adaptation selection process. Shetland ponies and Mammoth and Mastodons isolated on islands come to mind. On the other hand, I am aware of no research documenting this effect with LMB over time scales of a human lifetime. Please point me in the right direction if you are aware of one. My sense of LMB is that there is considerable adaptability already built into their genetics for environmental variation of food availability and competition. LMB from an environment where food is abundant and competition is low (they go together) have the genetics to grow slow as an adaptation to environment where they may have been stocked at too high a density. The opposite is also true. There is intense predation pressures for fish populations. I don't see this factor favoring slow growers or smaller fish so I think more than one factor would influence selection and that meaningful selection for slow growth or smaller ultimate weight potential probably would not rapidly occur (In other words, I think it would take more generations than Fyfer's fish have encountered). I doubt there exists any water that grows LMB at their maximum genetic potential over time. Competitive pressure and food supply always limit growth below this potential. For genetics to contribute meaningfully to growth and ultimate weight, the competition for resources must be subdued enough to allow genetics work their magic. I have yet to see a live Mammoth or Mastodon of any size.

See the next issue of PB mag - adaptation vs evolution . There is a lot we don't know. Just because no one has proved (peer reviewed study) how LMB might do is not an indicator that the problem does not exist. My experience from examining lots of stunted (overcrowded) LMB ponds has taught me that I don't want them as my source fish.

Pet hell, that was my working bronc back when men were men. BTW, don't ever try to cross breed a mammoth to a mastodon. She's too hard to get into the catch pen. Then you have to hold onto her while the introductions are being made. West Texas is a little different from the sissy places.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
