It looks like it. They seem reluctant to make changes but seem to be under pressure to do so. They claim that peak gobbling is around 4/23 (although I suspect that varies a lot from southern to northern MS). So I'm betting they push their season back one week from the traditional 4/15 opener.
But I could be wrong. It's a little hard to tell because this is a very poorly written article. They referenced the difference in TN's harvest numbers last year vs. this year with season changes, but they got the start dates wrong for both seasons (claiming that we opened 4/12 this year and 4/5 last), which completely skews the numbers. And there are a few paragraph that just don't make sense. Such as:
"Mississippi's fall season allows hens to be legally harvested. MSU's data illustrated a 2 percent increase in hen survival by eliminating a fall season thus increased populations by 2.5 times."
and
"Hunters were successful under the old frameworks even with controls for fluctuating habitat and bird populations. If we don't make more turkeys we can get more out of them."
To be clear, this is a critique of the author and publisher of this article, not MDWFP.
