Your license, fishing/reptile and I believe amphibian also, does allow you to collect up to 4 kings. It does not allow you to sell the kings or their offspring. California DFG is anal and rarely of any real help. They don't want you collecting and breeding. They don't want to deal with you and permits. So their answer is to make the permit for breeding and selling expensive. About $150 which if you consider the relatively small clutches of 6-8 eggs, the current price for cal kings in the KS classifieds, separate housing for the kings, food, etc. it's cost prohibitive. As a result of this many honest CA residents simply collect, breed, and sell without the permits. The cost, lack of help from DFG agents, and the regulations create a black market for cal kings. Just the opposite of what they should do.
Just my opinion.
