Cal. FGC § 15512

(a) If aquatic plants or animals are destroyed pursuant to subdivision (e) of Section 15505, and a claim is submitted pursuant to Section 15513, the owner shall be promptly paid from the General Fund an amount equal to 75 percent of the replacement value of the plants or animals, less the value determined by the department of any replacement stock provided by the department under subdivision (b). If the replacement value is not settled between the owner and the department, the replacement value shall be determined by an appraiser appointed by the director and an appraiser appointed by the owner. Appraiser’s fees shall be paid by the appointing party. Disputes between these two appraisers shall be submitted to arbitration under the Commercial Arbitration Rules of the American Arbitration Association.

(b) If the department provides replacement stock to an aquaculturist whose plants or animals are destroyed pursuant to subdivision (e) of Section 15505, the amount to be paid to the aquaculturist pursuant to this section shall be reduced by the value of the replacement stock, as determined by the department.

(c) The result of the arbitration or the amount settled between the owner and the department, reduced by the value determined by the department of any replacement stock provided under subdivision (b), may be submitted as a claim by the owner to the Department of General Services pursuant to Section 15513.
