I think, in my opinion, is that people just "can't see the tree's thru the forest" ... and I certainly open this discussion up to everyone ....
On a related matter, I lived in Maryland for 6 years. EVERY year the BIGGEST outdoor debate was about the Blue Crab population. Every year they told us that the Blue Crabs were in SUCH a decline that they had to change, shorten and close the season, as well as change the amount and sizes of Blue Crabs you were allowed to keep.
Mind you, Blue Crabs "do it all" as far as the Chesapeake Bay ecosystem is concerned. Along with Eel's and Menhaden, Blue Crabs are the #1 food source for the Striped Bass (Rockfish) as well as other fish in the Chesapeake and when the Blue Crabs were in decline, the numbers of Rockfish that were caught followed that decline. It is proven every year, when the crabs suffer, so does everything else from the fish to the fishermen who caught the Blue Crabs for a living.
BUT .....
When the state regulated the Blue Crab limits, everyone FREAKED and the thing that TOTALLY astounds me EVERY YEAR, is that they tell you that the Blue Crabs are in decline BUT, They still allow harvest of the Female Blue Crabs ........



And on a TOTALLY related note, there is a place at the head of the Chesapeake Bay called the Susquehana Flats where the Rockfish go to spawn every year. Thousands of pregnent females and milk bearing males all converge to this area to spawn every year and yet they open the season on the Susquehanna Flats for fishing!!!! Mind you, there is a "catch and release" rule in effect for the Susquehanna Flats but they say the mortality rate is brutal from improper handling and non-use of circle hooks! Yes, people are SUPPOSED to use circle hooks on the Susquehanna Flats, but you see pictures of people using jigs and other lures that have regular hooks on them.
... and if you thought about these two things I just stated, and if you thought about "how can we increase the amount of Blue Crabs and Rockfish in the Bay" .... Wouldn't it just be SO simple to close all harvest of Female Blue Crabs for a certain amount of time and to leave the Rockfish to spawn undisturbed...?!?!?!?!?!?!
I mention all of the above to illustrate the idea that if they closed the Walleye season during the PEAK spring spawning time, and let those Walleye "do their thing" undisturbed, wouldn't you think that the problems with Walleye populations would be alleviated with just a few years..?????
There is another post on this Great Lakes forum where all the fish are either FAT with eggs or FAT with sperm .... and all those people did was remove egg bearing females, and their counterparts from the breeding populace .... ?!?!... Its like shooting a gun and then complaining about the noise!!!
I remember when I was a very young kid living in Ohio for a short time, you could catch ALL the Yellow Perch you wanted. Then they put a bag limit on Yellow Perch and people FREAKED saying it wasn't the fisherman that were causing the decline of Yellow Perch populations, it was the Walleye and Coho Salmon that were eating the Perch ... but all the sudden, after they regulated the bag limit on Perch, BOOM, the Yellow Perch populations took off!
Isn't this the same scenario that can be corrected with the same measures that were taken years before...?
