REGARDING PREDATION RATES:
"Scientists say ducks must achieve 15 to 20 percent nest success in order to maintain the existing population, but scientific research showed that across much of the PPR, nest success had slipped below that level by 1990. Nest-raiding and hen-eating predators are known to be the major reason that nest success had slipped below maintenance levels."

So think about that the next time you are shooting your 6 duck limit/making a post about the good old days of the 100 point system/etc but lets talk about the Big Picture first...
BIG PICTURE
Farmers destroy nesting habitat to grow crops that are in such abundance that they sell for prices that are below the cost of producing them, what habitat is left and/or is restored via CRP/WRP in the US and DU in Canada, is raided by skunks, foxes, coons, coyotes, hawks, etc and yet the "DUCK INDUSTRY" wants liberal seasons and bag limits to maximize their profits...
THE PROBLEM
The problem, of course, is that most of yall dont know the truth and you dont want to know the truth so you are content to argue about spinners, season lengths, short stopping, etc...The truth is that even if the fall flight index of 100MM was really 100MM ducks, that is nothing compared to 100 years ago...We should be working towards a fall flight of 500MM ducks so there are so many ducks that none of the usual excuses about why we have no ducks would matter...Instead, DU, FWS and the other snake oil salesmen involved in the NAWMP set an artificially low "goal" of 100MM ducks so as not to upset the powers that be in American agribusiness...
The bottomline is this: American and Canadian Farmers have cleared up and are farming too much nesting habitat in the PPR to sustain the fall flights that serious waterfowlers want to see...These farming efforts have been paid for, either directly or indirectly, by US taxpayers...The crops produced sell at prices that are below the cost of producing them even though the true cost of production (which would include pollution, habitat degradation, etc) are not reflected in market prices...
In the short run, we are forced to deal with the symptoms of the loss of habitat which include artificially high predation rates due to concentrated habitat, whether hunters shoot steel shot or lead shot (if there were 500MM ducks nobody would care what shot we used), whether hunters use spinners or not, how long the season is, when it ends, etc...
Ducks hunters could and should lead a revolt against agricultural subsidies that dont contain an implicit counterbalancing offset to the unintended consequences of such subsidies...CRP/WRP in the US are an example of a counterbalance but those programs should be vastly enlarged and a Canadian version should be developed and implemented on a massive scale...DELTA WATERFOWL is in fact working on such an approach in Canada that they call "ALUS- Alternative Land Use Services"....As of yet, DU is not supporting ALUS.
Now you know the rest of the story.
