At interesting note on the bass and walleye season in MN. The DNR recently proposed that the opening weekend be 1 to 2 weeks earlier to allow for more fishing. They felt the fish were done spawning by then.
The idea met with a resounding NO by virtually all of the angling groups, resorts etc. The really don't like you messing with tradition!!!!
Logic would tell you if you take a bass off the nest and put it in a live well for a few hours...the chances of fry survival have to be close to zero.
A good article on the subject for largemouth bass stocking:
https://netfiles.uiuc.edu/mattd/MattsWeb/Diana%20and%20Wahl%202009.pdfIn Minnesota and Wisconsin the culture has largely changed from stocking to habitat improvement and it's made a big difference!
For example:
"It's a matter of economics and good fishing," says Drewes. He cited the example of Lake Bemidji, a 6,420-acre lake with a naturally producing walleye population. Based on current stocking rates, the DNR would spend about $63,000 each time to stock Lake Bemidji with enough DNR-raised fingerlings to replace natural production.
Drewes says, "By protecting water quality coming into the lake, reducing impacts of shoreline development, purchasing critical shoreline areas, and protecting and restoring eroding banks, we can sustain the fisheries like Lake Bemidji without needing to stock."
