California Code, Fish and Game Code - FGC § 8042

The amount of the landing fee under this article shall be determined by multiplying the fee rate for the type of fish delivered by a commercial fisherman in this state in accordance with the schedule in Section 8051 by the number of pounds, or fraction thereof, delivered. If the fee is imposed based upon weight in the round, and the fish is cleaned, gutted, beheaded, or otherwise not in the round at the time of delivery, the fees shall be adjusted by a conversion factor as determined by the department by regulation.
