After the effective date of suspension of this chapter, the operation of the commission shall be concluded and all moneys held by the commission not required to defray the expenses of concluding and terminating operations of the commission shall be returned on a pro rata basis to all persons from whom assessments were collected in the immediately preceding fishing season. However, if the commission finds that the amounts returnable are so small as to make impractical the computation and remittance of the prorated refund to these persons, any moneys remaining after the payment of all expenses of winding up and terminating operations shall be withdrawn from the approved depository and paid into an appropriate state or federal program conducted or used to fund activities related to the subject matter of this

chapter.
