A more obvious, and conveniently vegetarian option would be to use the ‘oyster plant’ or salsify – so Experiments in the artificial propagation of oysters book because of its supposed flavour.

Cloning of plants, or artificial plant propagation, commonly involves separating a portion of the parent plant in order to produce an independent plant. Almost any part of the plant, including roots, stems, and leaves, is capable of vegetative reproduction. The cloning of a plant can be accomplished in several ways, including the following.

Oysters are members of the family Ostreacea, class Bivalvia, in the phylum Mollusca. Under the current systematic schema, most commercially important species are classified in three major genera: Ostrea, Saccostrea, and Crassostrea and a number of minor genera (Carriker and Gaffney, ).

Adults are intertidal and subtidal bottom dwellers found worldwide. Oysters dine on ocean plastic The tiny mollusks take in microplastics, which may harm their ability to reproduce The oysters on these rocks Experiments in the artificial propagation of oysters book filter up to liters (50 gallons) of water per day, but they may be taking in some unwanted plastics along with that water.

Oyster farming is an aquaculture (or mariculture) practice in which oysters are bred and raised mainly for their pearls, shells and inner organ tissue, which is farming was practiced by the ancient Romans as early as the 1st century BC on the Italian peninsula and later in Britain for export to Rome.
