What do clams look like?

There are two shells, which are hard and thick, and slightly quadrangular. The shell is 36-48 mm long, 34-46 mm high, and the width is about 4/5 of the height. The left and right shells are equal. The shell tip is slightly bent forward, located in the middle of the back edge of the shell and slightly forward. The middle part of the shell surface is swollen, and it shrinks sharply towards the front, back and near the ventral edge, so that the front and rear edges are more or less rib-shaped, and the small moon surface and J surface are heart-shaped.

The growth lines on the shell surface are obviously thick, forming uneven concentric rings. The shell has a shell skin, which is white or light purple on the top and yellow-brown near the ventral surface. There is often a very narrow black ring on the ventral edge. The inner surface of the shell is grayish white. The hinge is wide. The left shell has a forked main tooth; the right shell has two main teeth arranged in an eight-shaped shape; the lateral teeth are well developed and are all in the shape of sheets.

Tips and precautions for buying clams

1. Choose closed clams when buying. Clams with open shells are dead. After being fried, such clams have a fishy smell and are full of bacteria, which affects the taste and safety. Pay special attention when choosing. If the shells of tightly closed clams cannot be opened after a long time of cooking, it means that they are dead and should not be eaten.

2. Wash the clams carefully. There is a lot of sand in the clams, so they must be cleaned before cooking. Put the clams in light salt water and let them sit for two or three hours to let them spit out all the sand.

3. Steamed eggs with clams are nutritious. Clams are best suited for steaming, which preserves their original flavor and nutrition. Steamed eggs with clams are fresh and refreshing. Eggs are rich in lecithin, sterols, calcium, iron, and a variety of vitamins. Clams are high in protein, trace elements, iron, calcium, and low in fat, and the combination of the two is more nutritious.

4. Try to eat clams on the same day. The bacteria that live in clams are very resistant to low temperatures, and even freezing cannot inhibit the growth of bacteria. It is recommended to eat them on the same day and not to eat them overnight. Even fresh clams should be fully heated. People with weak spleen and stomach should try to eat less to avoid diarrhea. It should be reminded that it is best not to eat clams with beer to avoid inducing gout.

Clams are molluscs with oval shells, light brown in color, and purple on the edges. They live on the shallow seabed and include many varieties such as flower clams, Manila clams, and Manila clams. Their meat is extremely delicious and is known as "the best in the world" and "the best of all flavors". They are also relatively nutritious, containing protein, fat, carbohydrates, iron, calcium, phosphorus, iodine, vitamins, amino acids, taurine, and other ingredients. They are low in calories, high in protein, and low in fat. They can prevent and treat chronic diseases in the elderly and are indeed high-quality and low-priced seafood. The oldest clam found so far is 507 years old (unfortunately, the researchers killed it during the study). In addition, clams are also known as one of the five immortal beasts on earth.

There are many types, with different locations and digs. The following is one of them.

What is the difference between clams and oysters?

Oysters and clams are both shellfish and their shapes are similar, so many people cannot tell the difference between them. In fact, if you look closely, there are differences between oysters and clams, so when buying, you should pay attention to its shape, color, etc. Although clams and oysters are similar, their cooking methods are indeed different.

clams

From the appearance, the clam shell is oval, light brown, with purple edges, yellow-brown near the ventral side, and often with a very narrow black ring on the ventral edge. The inner surface of the shell is grayish white, and the side teeth are only well developed and all in sheets. The external ligament is small and light yellow, and the internal ligament is very developed. Living in the shallow seabed, there are many varieties such as clams, clams, and tongue clams. The two shells of oysters are different in shape, with a rough surface and dark gray; the middle of the upper shell is raised; the head is relatively large and flat, with smoother edges; the inner surface of both shells is white and smooth, but it will show colorful patterns in the sun, and the two shells are connected at the narrower end by an elastic ligament.

Oysters

In terms of taste, the meat of clams is extremely delicious, and its nutrition is also relatively comprehensive. It contains protein, fat, carbohydrates, iron, calcium, phosphorus, iodine, vitamins, amino acids and taurine, etc. It is low in calories, high in protein, and low in fat, and can prevent and treat chronic diseases in the elderly. Oysters are the richest in zinc among all foods, rich in protein zinc, and are a good zinc supplement food, so they are known as a sacred aphrodisiac. They are very delicious and have a light smell of seawater.

The difference between oysters and shellfish - appearance

Oysters and raw oysters are two completely different things, although "raw oysters" are often called oysters in many places.

Or strictly speaking, oysters are a type of oyster.

Oysters are molluscs with two shells, one small and flat, the other large and convex; they are triangular in shape, with an eight-shaped dorsal and ventral margin. The outer surface of the right shell is light yellow, with loose concentric scales that are undulating in a wave-like pattern. The inner surface is white, and the surface of the shell is uneven. The meat is edible and can be used to make oyster sauce. The meat, shell, and oil can all be used as medicine. It is also called oyster clam, oyster roe, sea oyster, oyster, etc. There are many varieties of oysters living in different seas.

Oysters are one of the larger oyster species.

A large one with shell can weigh more than one pound.

It usually grows or is cultivated where rivers meet the sea, in the shallow waters of semi-brackish and semi-fresh bays.

Due to the limitations of suitable growth conditions,

Its number is less than other species.

Therefore, its economic price is generally higher.

Common charcoal grilled oysters and steamed oysters with garlic are of this type.

Difference in nutritional value

However, when it comes to zinc content, the difference between oysters and raw mussels is quite surprising:

Every 100g of raw oysters contains 71.2mg of zinc, while the same weight of oysters contains only 9.39mg of zinc. Raw oysters contain 7.6 times more zinc than ordinary oysters.

When it comes to zinc content, oysters are the clear winner, by a wide margin. No other food can come close.

Oyster meat has a protein content of more than 40%, which is rich in nutrition and delicious. It is known as the "milk of the sea" and can also be used as medicine. Therefore, the oyster with the "highest" zinc content that nutritionists have always advocated refers to "raw oysters", not ordinary oysters.

Oysters, also known as spiders, sea oysters, marine molluscs, meat for consumption, is a very expensive seafood in restaurants

Oysters, also known as sea oysters and oyster leeches, are a type of marine bivalve molluscs that live on rocks in suitable sea areas. There are many species of oysters, which are distributed along the coasts of northern and southern my country. The main species suitable for cultivation in southern waters is the pleated oyster; the species suitable for cultivation in northern waters mainly include the Pacific oyster and the Dalian Bay oyster.

Oysters have different adaptability to various factors in the aquatic environment due to different species, and the differences are even quite large. The suitable salinity range for the pleated oyster is 2.2%-2.6%. Higher than 3.0% or lower than 1.0% are not conducive to growth. The suitable water temperature for the growth of Pacific oysters is 6-32℃. When the water temperature is higher than 28℃ or lower than 6℃, the growth slows down or stops. It grows fastest when the water temperature is 15-25℃; the suitable salinity range is 0.6%-3.0%, and the optimum is 0.6%-2.6%.

There are many ways to cultivate oysters, including stone-throwing cultivation, bamboo-inserting cultivation, raft cultivation, floating raft cultivation, bottom seeding and proliferation. Due to different cultivation methods, the designed per-acre yield is also very different. Taking the raft-type cultivation of pleated oysters as an example, rafts are set up at the lower edge of the tidal stream and low tide zone, and oysters are raised on the rafts. Each raft is 50-60 meters long, and a string of oyster seedlings is hung every 30 centimeters, with about 30 pieces in each string; the distance between rafts is 3-4 meters, and 2-2.5 rafts are one acre. Generally, it can be harvested after 7-8 months of cultivation. The harvest season is from January to April. The size of the individual is 7-8 cm in shell length, and the general per-acre yield can reach 6-10 tons (fresh weight with shell).

clams:

It is a hard-shelled mollusk that grows in both seawater and freshwater. In the past, people mainly ate freshwater clams, which are not called clams but mussels or shellfish.

What is the difference between oysters and clams?

Summer is here again, and grilled seafood is on the table. Many people like these foods, and their popularity is unimaginable. In fact, on some menus, customers just choose according to their taste habits, and rarely understand their essence. As for the difference between oysters and clams, many people don't know what it is. So what is the difference between the two?

Oysters are farmed in the sea, so you will find them very expensive on the menu. Because the meat of this mollusk is rich in nutrition, it is often found in the southern coastal areas, and there are many types, so there are naturally different choices. It has great requirements for the growth environment. The salt content must reach 2%, and the water temperature should be around 20 degrees, so that it can grow faster. As for clams, they can grow in both seawater and freshwater, but they are hard-shelled types. They taste different when taken with you, and the former is more moist.

This is the difference between oysters and clams. The former have various types of cultivation and are mostly farmed in seawater, have high requirements for the environment, and the harvest is very rich. The latter can be farmed in both fresh water and seawater, have strong adaptability, and generally speaking, there are certain differences in the environment.

I believe that everyone may often eat seafood in daily life, and among seafood, oysters and clams are the more famous. So what are the differences between oysters and clams? Let's talk about it in detail, which can also better help us to evaluate, distinguish and choose, and achieve better demand effects.

Difference Between Oysters and Clams

The difference between oysters and clams in appearance

First of all, there is not much difference in appearance between oysters and clams, because both of them are fierce creatures in the ocean, so they are both in the shape of shells, but there are certain differences in the shape and color of their shells. The shells of clams are relatively unique in shape, so they look very strange, and their patterns are mainly black and white. As for oysters, their shells are relatively irregular, so the colors are more complicated, so the difference between them and clams is quite obvious.

Nutritional Differences Between Oysters and Clams

The nutritional value of oysters and clams is very high because they contain a lot of protein and corresponding nutrients. At the same time, some of the trace elements in them are very good for helping to improve the nutritional balance of our body and prevent and treat certain diseases. This is why many people can improve their bodies by eating oysters and clams when they need to recover after surgery or when they have certain diseases. They are indeed a high-protein food and are very helpful to our body. You can also try them in your daily life.

The difference between eating oysters and clams

The difference in eating methods between oysters and clams is relatively similar. As they are marine seafood, they can both be cooked using some homely methods. They can also be steamed with minced garlic or cheese, which are relatively delicious. Of course, you can also add certain sauces based on your own innovative cooking methods to better enhance the corresponding taste.

In short, for oysters and clams, the differences in appearance, nutritional value and eating methods are actually not particularly large. In daily life, we can distinguish them through some life experience and differences in appearance. This will help us achieve better needs and effects, which is a great help to our bodies.
