California Code, Fish and Game Code - FGC § 853

(a) The director may deputize any employee of the department to check persons for licenses required under Section 7145 and to enforce any violation of that section.

(b) Before a person is deputized pursuant to this section for the first time, the person shall have satisfactorily completed a training course meeting the minimum standards of, and comparable to, the training for “level III reserve” as set forth in the regulations of the Commission on Peace Officer Standards and Training.

(c) A person, who is deputized for the limited purpose stated in subdivision (a) shall not enforce any other provision of this code. Being deputized under this section does not make a person a peace officer subject to Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code.
