98% will be male. that seem's high. I wonder if he meens just this typ of hybrid.

Sure, hybrids exist in nature. It's a question of how important or common (or viable/fit) they are outside of specific transition zones for some species. There's also a large amount of variation in natural populations, and these are not nearly always the same phenomena. Therein lies the rub, to coin a phrase.
In light of what has been found in the last few years, especially with respect to what we consider as humans, hybridization between species despite being infrequent can be very important. Resultant populations can relatively reshuffle deck resulting in a new population where come key gene complexes or alleles provide some selective advantages that was not possible prior to the hybridization event. The advantages can even override reductions (temporary) in fertility of the hybrids. At some point the population can then be said to be no longer hybrid once once everyone can be homozygous (with respect to parental species source) for a given set of alleles.

Centrarchid that is very interesting, there is a river in Arkansas that I read a report on several years ago where Redbreast sunfish were stocked, they completely hybridized with the local Longear, and according to surveys some of the local Longear are larger than populations in other areas and exhibit some Redbreast features.

I am familiar with alleged situation and think it is probably the actual case. The Redbreast features are evident to my eyes. This weekend I will be taking a class on a field trip to the same location.

How did the field trip go, any pics....survey information?
