The size of the shells of bivalve mollusks also differs in diversity and varies from 0.5 to 100 cm, but, as a rule, is within 10 cm.
The bivalve, as a rule, leads to a sedentary, near-bottom way of life, can be attached to the bottoms of ships, to other moving and stationary objects. Scallops, which is independently capable of moving for short distances, are located somewhat apart.
The shell of a bivalve mollusk has, as a rule, a symmetrical shape, but sometimes an asymmetric structure is also encountered. The shell consists of several layers: the inner (mother-of-pearl), middle (calcareous) and outer (horn). The shell has a protective function and can be considered as an external skeleton.
Despite the large variety of bivalve mollusks, they all have a fundamentally similar internal structure. The nature of nutrition and the respiratory system are the same: they all have gills, which also perform the filtering function, contributing to the retention and further (through special cilia), the delivery of food into the mouth. This way of feeding allows to refer all bivalve mollusks to the so-called filter feeders.
Bivalve mollusks reproduce both sexually and asexually (hermaphrodites) in ways.
Bivalve mollusks play an important natural role: being filtrates, they participate in the purification of water bodies from various organic components, in addition, mollusks are an important link in the food chain for many fish and a number of mammals.
A number of bivalve mollusks (mussels, oysters and scallops) are eaten. A man has long appreciated the taste and beneficial properties of the above-listed mollusks.
However, the value of bivalve mollusks is not limited to their remarkable taste, mollusk is an indispensable source of micro and macronutrients, vitamins, polyunsaturated fatty acids and essential amino acids, that is, everything that is necessary for normal functioning of the body, maintaining health and high performance.
Eating clams can be eaten raw (oysters), and you can cook various dishes from them. At the same time, it is very important that the mollusks are fresh, preferably caught immediately before use. It is not uncommon when the use of oysters of not “first freshness” ended in severe food poisoning. It is also necessary to strictly dose their use, since the ingestion of a large number, even fresh mollusks, can cause intoxication with saxitoxin-accumulated as a result of filtering a large volume of water and absorption of microorganisms present in it.
Thus, fresh mollusks are the prerogative of those who live on the seashore or have the opportunity to pay for their express delivery. The rest of the rest is fresh frozen or canned mollusks.
A good alternative to providing the population with useful components contained in bivalve mollusks is bioactive additives based on them. With proper preparation, the preparations retain all the beneficial properties of the original product, while it is easy to transport, store and dispense.
In our country, the company engaged in the development and production of bioactive drugs based on marine inhabitants is PharmOns Lab., Which produces the DOCTOR MORE product line.
Production is located in the Far East region, which allows to obtain raw materials from environmentally friendly regions of the Sea of Okhotsk and the Sea of Japan, and the use of the latest technologies of gentle processing ensures the initial preservation of the most valuable components. The company’s products are designed to make a significant contribution to strengthening the health of Russian citizens.
