Aquaculture According to the FAO, aquaculture is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc.articular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and plant farming.

- Bivalves. The mollusks that have a hinged, two-part shell joined by strong muscles are called bivalves. Clams, Oysters, and Scallops are bivalve mollusks and are a familiar food source. These three animals pull their shells closed by contracting powerful muscles near the hinge.The open these shells they have to relax their muscles.quid and octopuses have a well-developed nervous system and large eyes which are similar to human eyes. Cephalopods are the only mollusks that have closed circulatory system, which the blood contains food and oxygen that moves through the body in a series of closed vessels.

- Aquaculture is practiced at many different levels. Fish are farmed for recreation and profit. The difference depends on the number or density of fish raised per surface acre (one acre, four feet deep -- 4 acre-feet) of water. Management skills and equipment needs become more technical as the number of fish produced increases. It is important to ...

MOLLUSKS Most mollusks have a rasping tongue called a radula, armed with tiny teeth. This scrapes tiny plants and animals off rocks or tears food into chunks. Bivalves, such as oysters and mussels, filter food particles from the water with their gills. Cephalopods such as octopuses and cuttlefish are stealthy hunters. Octopuses creep along the seabed or lie in wait for fish and crabs.

- Growing your own oyster mushroom is fairly simple. In fact, they are much easier to cultivate as compared with Portobello and Shiitake mushrooms. Oyster mushrooms can adapt to a wide range of substrate like sawdust, straw, paper, leaves, and more. But remember to grow them in a hygienically safe way.

Oysters Admittedly, they’re not for everyone, but adventurous humans the world over have enjoyed oysters, raw and cooked, for thousands of years. Although it is possible for food oysters to produce pearls, they should not be confused with actual pearl oysters, which are from a different family of bivalves. True oysters, which belong to the Ostreidae family, are found throughout the world’s oceans, usually in shallow waters and in colonies called beds or reefs.

- Less than 1% of clams dug with a mechanical shellfish-digger (early hydraulic conveyer dredge) were damaged in Canada (Dickie and MacPhail 1957). Contemporary mechanical harvesting in South Carolina documented minor damage to the shell matrix among 5% of harvested oysters (Collier and McLaughlin 1984).

How do oysters make pearls? Pearls are the result of a biological process -- the oyster's way of protecting itself from foreign substances. Oysters are not the only type of mollusk that can produce pearls. Clams and mussels can also produce pearls, but that is a much rarer occurrence. Most pearls are produced by oysters in both freshwater and saltwater environments. To understand how pearls are formed in oysters, you must first understand an oyster's basic anatomy.

The Green List: US Farmed fish In the US they are farmed in closed recirculating systems and they require less fishmeal than other carnivores, meaning farmers get a lot of fish for how much feed they put in. They have a sweet, mild taste and delicate texture, comparable to Chilean seabass.

Spider bite or MRSA? Spider bite pictures and symptoms. The black widow and brown recluse are most common in the Southern U.S. and both like warmer weather. While bites are uncommon, you are most likely to come across these spiders in undisturbed places, such as the back of a closet or garage or in wood pile.

Cultured freshwater pearls Cultured freshwater pearls are pearls that are farmed and created using freshwater mussels. These pearls are produced in Japan and the United States on a limited scale, but are now almost exclusively produced in China.his mussel produced a high volume of low-quality pearls that came to be known as  Rice Krispie pearls in the 1970s and 1980s. More than a decade ago the freshwater pearl industry of China shifted production from the cockscomb pearl mussel to the triangle shell mussel (Hyriopsis cumingii).

Worldâs Biggest Pearl? Massive Oyster Could Contain Golf-Ball Sized Gem An oyster produces a pearl when an irritant slips inside its shell, prompting the invertebrate to cover the foreign object with a substance called nacre. Layers of this material coat the object, forming a pearl. It's been a good year for oyster-hunters.

Section 1 - Mollusks Section 1 - Mollusks. Mollusks are invertebrates with soft, unsegmented bodies that are often protected by a hard outer shell. In addition to a soft body often covered by a shell, a mollusk has a thin layer of tissue called a mantle that covers its internal organs, and an organ called a foot.Mollusks have bilateral symmetry and a digestive system with two openings.Most species of mollusks have an open circulatory system, in which the blood is not always inside blood vessels. Most mollusks that live in water have gills, organs that allow oxygen from the water to enter the body.lams, oysters, scallops, and mussels are bivalves. Bivalves are mollusks that have two shells held together by hinges and strong muscles. Bivalves live in all kinds of watery environments. Bivalves do not have radulas.

Oyster Nutrition Facts Oysters are available either farmed or wild and are harvested in both the Pacific and Atlantic Oceans. Since farmed oysters are grown in living conditions that are similar to wild oysters, there doesn't appear to be any difference as far as nutrition goes. Health Benefits. For such an unassuming food, the oyster is packed with nutrition. One serving of oysters has about 5 grams of protein and about 2 grams of carbohydrates. They're also high in calcium, potassium, magnesium, and vitamin B-12, as well as zinc and iron. Zinc is a mineral your body needs for many different biochemical processes to occur and is crucial to the immune system.

"Fact or Fiction? Following the ""R"" Rule for Shellfish" Many shellfish, especially oysters and mussels, are also now farmed instead of harvested from the wild, further decreasing the chance of contamination. The other argument for the R rule is that shellfish usually spawn during the summer months. A rest is needed to let the shellfish repopulate.
