A short video on NYS DEC's heritage brook trout program. I'm not a fan of "strains" and not a fan of splitting hairs on the importance of one population over another. That's getting awfully close to speciation.
I will say that I was in a presentation last year where the geneticist showed the uniqueness of some of these isolated pond strains in NY. One, in particular, appears to have developed the ability to cope with extremely warm water temps. I was on the phone last night with a geneticist from NY and he said they temped the pond in the upper 70s last year. They've apparently found somewhere around 15 unique populations in the ADK area. I know some of the ST in ME ponds seem to be withstanding some really warm temps too.
So the push in NY is to further protect these unique populations that appear to have adapted better than other populations to warming trends. I'm not sure I like where that's headed, but at least there's a serious effort to look at them closely. If nothing else, they're gathering a lot of data on their populations.
