When farmed, the temperature and salinity of the water are controlled (or at least monitored), so as to induce spawning and fertilization, as well as to speed the rate of maturation – which can take several years. ![]() Oysters naturally grow in estuarine bodies of brackish water. The oysters would get shipped to Italy, where Roman Emperors would pay for them by their weight in gold.Ĭommonly farmed food oysters include the Eastern oyster Crassostrea virginica, the Pacific oyster Crassostrea gigas, Belon oyster Ostrea edulis, the Sydney rock oyster Saccostrea glomerata, and the Southern mud oyster Ostrea angasi. The area's “kentish flats” have been used since the Romans started. Another place in England that is famous for its oyster fishing is Whistable. ![]() A couple of years later the company closed its doors and all the assets were sold by 1881, closing the oyster farming in the Thames Estuary area in England. This act prevented the sale of dredged oysters from the months of June through August, and freshwater pond oyster sales from between May and August. This caused the government of England to make the 1877 Act to solve the problem. In the 1870s the oyster trade suffered from overfishing and sent the industry into a decline. Then on July 25, 1864, The Herne Bay Hampton and Recuiver Oyster Fishery Company moved into the area to start oyster farming. They would export the oysters back to Rome and throughout the Roman Empire. The Ancient Romans started farming the Thames Estuary in Hampton-On-Sea, or Kent, England from the 1st Century to approximately the 4th Century. Some time later the wall was covered with spat coming spontaneously from the sea which gave 2000 baby oysters per square metre. After obtaining the rights to a part of the coast he built a wall to make a reservoir and to break the strength of the current. An important step to the modern oyster farming was the oyster farm built by Hyacinthe Boeuf in the Ile de Ré. In 1852 Monsieur de Bon started to re-seed the oyster beds by collecting the oyster spawn using makeshift catchers. He did this by cultivating the mollusk with a system that could control the water levels. The Roman engineer Sergius Orata is known for his innovative ways of breeding and commercializing oysters. In fact, the Romans were the very first to cultivate Oysters. With the Barbarian invasions the oyster farming in the Mediterranean and the Atlantic came to an end. Oyster farming was practiced by the ancient Romans as early as the 1st century BC on the Italian peninsula. Want to become an oyster gardener?

All of the returned oysters are transplanted onto sanctuary (non-harvest) reefs in nearby waters. Gardeners will grow and care for their oysters in the cages for about one year and will return the mature adult oysters to CBF at an Oyster Roundup the following summer. At the end of the seminar, they will have the option to take home spat-on-shell oysters (baby oysters set on recycled shells) and two 18" x 9" cages to grow them in. How Is It Done?įirst-time oyster gardeners are required to attend a short seminar to learn how to maintain their oyster garden over the coming year. ![]() Once grown, the adult oysters are returned to the Chesapeake Bay Foundation for planting on sanctuary reefs. The Chesapeake Bay Foundation's Oyster Gardening Program gives citizens an opportunity to help bring back this vital species by growing oysters alongside their docks. Unfortunately today's oyster population is a small fraction of what it used to be. They also provide essential habitat for fish and other Bay creatures. Oysters are the Chesapeake Bay's best natural filters. Join a community of over 300 citizens in Virginia who are doing what they can to clean up the water. Oysters are the easiest pets you'll ever own because everything they need to survive is in the water. Did you know a single adult oyster can filter up to 50 gallons of water a day? Imagine how clear our waterways would be if we had more oysters! You can help us! By becoming an oyster gardener, you actually become a "foster parent" for a few hundred baby oysters. ![]()
