Crappiewhipped,
When you refer to 'possession limits' in your post, I'm thinking your are referring to daily creel limits so that is how I will address my reply.

If there are two or more anglers in a fishing group then each individual angler's catch will need to be identifiable. This can be through separate livewells, divided livewells, separate buckets, coolers, or two anglers could share a livewell or other container if one of the anglers places their catch on a stringer. If checked by a Conservation Officer the CO will want to know what fish belong to what angler so he can check daily creel limits as well as fish lengths if it is length limit lake. Many anglers throw all their fish into one livewell. If one short fish is found then the big question is who is the owner of the short fish. Same thing with an over limit scenario...which angler is responsible for the extra fish?

Well guys, I was WRONG with my post above and apologize for posting misinformation. LE questions are my Achilles Heel and I didn't fully check all of my sources before replying, obviously a very dangerous practice. I've left the misinformation in place so as to not leave kscrappeye hanging with his post.
Now for the correct answer to Crappiewhipped's question: No, you DO NOT need to keep catches from multiple anglers separate (unless you are fishing "flowing portions and backwaters of the Missouri river and in any oxbow lake through which the Kansas-Missouri boundary passes"). City or county operated lakes could have different regulations so always check local regulations.
