Here's an interesting (scientific, not hearsay and opinions) comparison between Granby and Blue Mesa Lakers....

I'm not a biologist, but I can appreciate the info presented here to help understand the requirements to grow big macs. Check out the girth diference between the Blue Mesa (tunas)and Granby fish (snakes) - those old Granby fish look starved! Another interesting bit of info shows that the Granby fish growth has decreased to almost a standstill...so even if you release that 26" hoping that it will grow into a trophy fish, it will take another 10yrs for it to grow to 30", and it will still only be 9lbs-so is it actually better for the fishery to keep more and increase the growth rate and have a few healthy fish vs. a ton of skeletons swimming around?
pretty interesting........
