(a) The plant hydrilla (Hydrilla verticillata) is a noxious aquatic weed not native to the State of California. The Legislature hereby declares that the further introduction and spread of this serious aquatic weed pest would be detrimental to the state, causing irreparable damage to the agricultural industry and recreational use of streams, lakes, and waterways and further that the eradication of this aquatic weed pest is essential to the preservation of the environment. Hydrilla can be introduced into the state in shipments of fish and aquatic plants for wholesale and retail sale within the state. It can become established when aquariums containing hydrilla are dumped into California's streams, lakes, ponds, and waterways. Subsequent spread is rapid, both naturally and artificially.
