Obtuse,
Each angler is allowed to land one limit of fish per day, per trip. That's the law. You can give them away, but you can't land anymore that day.
What I am saying is that the secenarios that you described are against the rules of the NY DEC. Interesting legal theory or not, anything the DEC Commissioner passes, or that is written in the Environmental Law, stands, and is only reversible by the NY State legislature. I don't stop people from sharing catches on my boats, and most owners wouldn't stop a client from coming back in the afternoon after making a limit trip in the morning. An ECO may not even bother w/ the infraction. But, it is a law, and people, whether they want to do it or not, must realize that they are in fact violating laws.
It seems inocuous that someone can land a limit on a morning trip, get rid of the catch and go back for a limit in the afternoon. Does it seem OK if a guy in a private boat goes out, catches a limit of stripers, brings them back to hi house, doers it again, brings them to his neighbors house, does it again(Do I need t continue?). The fact is, the landings projections are based on each angler's possible success at the given regs. So when co-mingling is allowed, it becomes easier for more anglers to realize their limit, and that would require an adjustment of the regs.
I love the way people get into semantical and wording debates here, but when the real world event comes around, they either dump their catch when they see the ECOs coming, or sit there w/ their mouth shut when they realize that the ECOs aren't interested in hearing what Jonny Cochran has to say. You'll also find the judges that sit at these hearings are equally disinterested in consittutional-level arguements. If you want to feel right, then you are right. As long as everyone else understands that it is illegal, have your fun.
