I'd say 90% guided trips are catch and creel. Salmon or steel . I also believe that how far one traveles to fish also contributes to creel or release . A guy going an hr to fish is going to creel less, well to an extent.
Once you get out of the zone I honestly believe the majority of fishers are going to keep at least 1 fish. Personally I know some who do as Clint said.
I don't think harvesting more is the answer , remember , the lake limits are higher then tribs.
As for stripers and slots.
I do think you , Trev we not really a slot but a min size
Slots SUCK IMO . Not saying that protecting spawners are a bad thing or possibly necessary but a slot limit using live bait is not the answer . Anyone who fished slots for lakers on Ontario can attest .
The stripers along the coastal shorelines are much different then spawning fish in my ( our ) trib.
I have fished striped bass here since the 70's. we slaughtered them then and very few recreational fishers but MANY comercial fishers .
Comercial fishers raped the seas and winter migratory holding areas.
The early - mid 80's got so devistated , it wasn't even worth fishing then here.
Marine regs imposed a comercial restriction and it worked , 100 fold. The fish rebounded to peak levels about 10-15 years ago, and so did the recreational fishers ( here )
Now was the bait ( herring ) issue. Again regs were imposed, no trib netting and 10 herring limit.
So with the new spawning protection slot, imposed herring limit. My guess is in 5-7 years the stripers will explode and the herring ( bait ) will be off limit as in some states ( tribs already ) .
Tricky stuff this fishery game..
