I didn't get a chance to read all of it. But, figured some members here (cough, Ron,cough) would like to read it.

Thanks for the thought. I did read through it and it sounds like the real article is in L'an Cichlidé vol.11.

IMO, this is the main thing to take away:
Quote
Darwin’s theory of evolution proposed the concept of the inferiority of hybrids, which coupled with the survival of the fittest principle were unable to remain as a viable linage.

And I disagree with this assessment:
Quote
This is one more thing to think about when we see species introduced into exotic waters, as the long term effect is impossible to anticipate. We can only be sure of one thing, there will be an effect that will change their evolution for eternity.
Sometimes when exotic species are sometimes introduced, on some occasions they are unable to compete, die out, and don't have a significant effect. While it's quite often as quoted, it's not always the case.

This article was not talking about the Nile Perch and Tilapia released into lake Victoria or the Peacock bass in Florida?
