Any reduction plant in which any fish or any part thereof is used in violation of the provisions of Sections 7700 to 7706, inclusive, 7708, 8151, 8153 to 8157, inclusive, and 8075 to 8080, inclusive, of this code, or in violation of any regulation of the commission, is a nuisance.

If the existence of a nuisance is established in such action, an order of abatement shall be entered as part of the judgment in the case, which order shall direct the closing, for 12 months, of the building or place where such nuisance was maintained, and, during such time, the building or place shall be and remain in the custody of the court.
