Thanks for calling KDFWR.
I agree with you personnel preference on culling. I would call that guy back and ask him to read the first paragraph in the 2016 fishing regs and then see what he says about culling with an additional fish when there is already a daily limit in the boat. The same sentence "seems" to also give permission to keep fishing after a limit is reached as long as you don't keep or cull using the additional fish. Here it is. Seems like pretty plain English to me.

If you do call him back can you report what he says back here please.
