Types of oysters: a complete list. Types of oysters for pearls

Information about the extraction of oysters takes us away from time immemorial - in the Neolithic settlements of man who settled along the coasts of the oceans, in huge quantities there are shells of these mollusks. In Korea, Southern Primorye, and also in Japan, the length of ancient oyster piles sometimes reaches hundreds of meters. In this article, we will look at the most common types of oysters listed below.

Varieties

In nature, almost 50 species of these mollusks are known, the bulk of which can be eaten. For living they most often choose the tropical seas, but there are several species living in the waters of the cold northern seas.

Oysters can be divided into 2 groups depending on the shape of their shell: flat, deep and round. Flat, which are most appreciated by lovers of this seafood, live on numerous shores of the shores of the Mediterranean and the Atlantic. This species is represented by 4 varieties, each with its own unique taste qualities, its own price category, and also external features.

Maren Oleron

These species of oysters in France have the same name with their habitat - Maren Oleron district, Charente province. They are the most outstanding representatives of the mollusks of this group and have long been recognized by gourmets from all over the world thanks to their surprisingly delicate taste. The main characteristics are the presence of shells of almost circular shape, as well as the greenish color of the meat.

Gravette

These oysters grow in the basin of Arcachon. They are quite fleshy, despite their small size, as well as unsalted taste. Their shell has a greenish-yellow hue.

Belon

We continue to consider the types of oysters. The list will be incomplete, if not to say about Belon. They also received their name due to their habitat - a small coastal village located in the north of the province of Brittany. To date, almost all oysters grown in Brittany have received this name. A distinctive feature is the grayish-white coloration, as well as the presence of a sharp iodine odor.

Types of oysters: fin de cler

Their name is given in honor of the cages, where they are grown. The duration of this process is one month, while up to twenty individuals can be located on one meter. Special algae varieties are used as their supplemental food.

Specialty

These types of oysters differ from the previous variety by fleshiness and greater density. Such qualities are obtained due to the two-month holding of mollusks in special cages. One meter of the square lives on 10 individuals.

Croesus

Such species of oysters are bred near the coasts of Ireland and Normandy. Cold Atlantic waters have an interesting influence on the development of these mollusks, contributing to the increase in the density and fat content of meat.

Blue shell

These oysters are bred and grown in an interesting way. They are transplanted into special pools filled with blue clay for the 2nd and 3rd years of life. This is done to enrich them with an additional amount of trace elements (phosphorus, iron, copper, zinc) and vitamins.

Brittany

These species of oysters are grown on the southern coast of the province of the same name in France. Their unique feature is a rich, pungent taste with a slight metallic taste.

Oysters white pearls

Considering the types of oysters for obtaining pearls, it is worth highlighting this one. They have an elegant shell shape, in which this mineral grows. Seafood experts also recognize them immediately for the sharp smell of iodine and a pleasant sweetish taste.

Hasan

These oysters differ in longitudinal-wavy structure. The color range of shells - from white to dark olive or Burgundy. This mollusc is the most laborious in extraction - it is mined on underwater rocks, great depths, in places with fast currents. Has a unique ratio of total weight to body weight. You can say that this is the most beautiful oyster of all.

Oyster aniwa

This oyster can be called a fine nature with a strong character. She lives on the island of Sakhalin, near the village of Solovyovka, in the Gulf of Aniva, thanks to which it got its name. This shellfish is so popular that neighboring Japanese periodically visit Sakhalin specifically behind it. A deep, elongated, narrow shell shape resembling a boat, an interesting salty aftertaste and a mild greenish color distinguish it among the other oysters.

Oyster posietska

Considering different types of oysters, it is worth highlighting this. It is very exotic, because it lives on bioherms (underwater hills), the lower part of which is buried 10 meters deep in the mud. Interestingly, when examining the leaves of the lower layers of extinct oysters, they were about 8000 years old. This period coincides with global warming, as well as rising sea level, and this resulted in an increase in the growth of the hills.

This oyster has the most unusual appearance. To be more precise, it is formless, so sometimes you will not understand what it is. The weight of the mollusk reaches 1.5 kg. Having an average weight of 600 grams, it reaches 25 cm in length. The airy light oyster has very tender meat, and also has a sweet taste and an unusually fresh smell. This gives her the right to be the model of oysters.

Japanese

Queen of the lagoon Busse of Sakhalin Island. The giant oyster lives at a depth of up to 7 m, sometimes forming solid settlements (oyster banks). The body of the mollusk is enclosed in a shell oval-wedge or irregularly rounded, white in color. The left (lower) sash leaf - they oysters grow together - more convex shape. Both valves have radial wide folds, and also are covered with concentric thin plates.

The main habitat of mollusks are warm subtropical and tropical seas. Although in temperate latitudes, in which the water temperature reaches 16 ° C in summer, oysters can reproduce and live.

The main danger for these mollusks is represented by sea stars, some representatives of gastropods, sponges-clions.
