Is a small river prawn a black shell shrimp and a black tiger prawn a sea prawn or a river prawn?

Small river shrimp. It is a white shrimp shell. You're talking about black-shelled shrimp.

Black-shell shrimp are a type of river shrimp because they can live inside rivers. In addition to living in rivers, they can also survive in freshwater waters such as ponds, lakes, and streams. It belongs to freshwater shrimp and cannot survive in salt water.

River shrimp grow in a completely different place from black-shell shrimp, although both are freshwater shrimp, but due to the different food they eat, their growth environment is also very different. River shrimp are more likely to grow in rivers and lakes and feed on plankton in the water. Black-shelled shrimp grow on aquatic weeds and thriving algae.

Where there are many plants, they feed on algae plants. The black shell shrimp has a very practical pair of clawing claws than the river shrimp, which can help them harvest food more easily. In addition to this, the color of the river shrimp is mostly the same, while the color of the black shell shrimp can change depending on the environment.

And, most importantly, they don't have the same effect on humans. Due to the delicious meat, river shrimp is rich in astaxanthin.

As a result, river shrimp has become a high-quality aquatic product for consumption. The black shell shrimp is not edible because of the lack of astaxanthin, and the abundance of scavenging and algae, so everyone usually puts the black shell shrimp in the aquarium. Black shell shrimp are gentle and do not attack fish, and they are very useful because they are able to eliminate algae from the aquarium.

Difference Between River Prawn and Black Shell Prawn.

There is a certain difference between river shrimp and black shell shrimp, and their specific differences are as follows:

1. The living environment is different

2. The food is different:

Generally, river shrimp feed on plankton in the water, while black-shell shrimp feed on algae plants.

3. Different body types:

Black shell shrimp have a very practical pair of clawing claws than river shrimp, which can help them harvest food more easily.

4. Different colors:

The color of river shrimp is mostly the same, while the color of black-shelled shrimp can change depending on the environment.

5. The edible value is different

In general, river shrimp refers to a high-quality aquatic product that can be used for food, and moderate consumption is beneficial to the human body; Black-shelled shrimp are not edible.

All in all, river shrimp and black-shell shrimp have different living environments, different foods, different body sizes, different colors, and their edible value is also different. However, both of them belong to freshwater shrimp.

River shrimp should be a general term for freshwater shrimp, and black shell shrimp is just one of them.

Black tiger prawns belong to the category of sea shrimp. Black tiger shrimp, also known as giant shrimp, is the most common species in the world, in addition to the same as ordinary shrimp, its astaxanthin content is about 20% higher than that of ordinary shrimp, so it is relatively high during the Spring Festival. Black tiger shrimp has a wide distribution area, from southern Japan, south Korea, China's coast, the Philippines, Indonesia, Australia, Thailand, India to the east coast of Africa.

There are two spawning periods in the coastal areas of our country every year, in February and April and August and November.

Morphological characteristics: large markingsThe body of the black tiger shrimp is arranged alternately with dark green, dark brown and light yellow transverse spots, forming a bright markings on the abdomen. The upper beak of the frontal horn is 7 8 teeth, and the lower beak is 2 to 3 teeth. The lateral frontal sulcus is quite deep, extending behind the supraocular spine, but the lateral ridge of the frontal horn is low and blunt, and the posterior frontal ridge ** groove is distinct.

There is a pronounced hepatic ridge and no frontal ridge. Strong vitality, delicious meat, large individual, the largest of the shrimp genus, the largest female shrimp up to 33cm long, weighing more than 500g.

The little red shrimp is a giant river prawn in the river, not a sea prawn.

The real name of the small red shrimp is "Yuan's crayfish", which is a freshwater shrimp that is related to lobsters, and taxonomically they are all "decapods". Lobsters are in the lobster family, crayfish family, or crayfish family, while the crayfish we eat are in the crayfish family.

<>No, black-shell shrimp.

It belongs to the rice shrimp series, and the large shrimp of rice shrimp will not eat small shrimp.

Black shell shrimp is a very gentle shrimp that will not attack any fish in the tank, does not need to be fed, does not require high temperature (but try to avoid high temperatures), and is good for suppressing algae in the tank.

The flooding has a very large effect, so the black shell shrimp can be said to be a very good fish tank cleaner. However, because of the mildness of the black shell shrimp, they also lack the ability to defend themselves, and the shrimp and juvenile shrimp in the molting stage are very vulnerable to being injured or eaten by the fish. Therefore, when raising fish in the tank, try to plant more aquatic plants or place facilities such as shrimp houses for black shell shrimp to hide.

1. Water quality. Since the native places of black shell shrimp are lakes, reservoirs and ponds with relatively clear water quality, the content of ammonia nitrogen and organic matter in the water body is low. If the water quality is not good enough, the ammonia nitrogen and inorganic salt content in the aquarium will be relatively high, and the black shell shrimp is extremely sensitive to this.

2. Temperature. The water temperature suitable for the growth of black shell shrimp is 23 -28 , * should not exceed 30 . When the temperature is too high, the microorganisms in the water will multiply due to the decrease in the oxygen content of the water, which will lead to the spoilage of the water, similar to the crystal shrimp.

3. Polyculture. It is recommended to polyculture with lampfish, guppies, etc., do not choose to polyculture with carnivorous fish, maybe you won't be able to find them in a few days, because they may have been buried in the belly of the fish.

4. Sufficient dissolved oxygen. The requirements for dissolved oxygen in water for black-shell shrimp are even higher than those for ornamental fish, and the dissolved oxygen content of the water body should generally be kept at least 5ppm. In the summer, owners can add oxygen to the aquarium by changing the water frequently, or add oxygen equipment to the aquarium.

5. Direct stocking. If you are a black-shelled shrimp caught from the wild, then it needs to have a process of crossing the water so that you can avoid the discomfort of sudden changes in water quality. The method of water crossing is similar, the water source is slowly injected into the fish tank, so that the water quality of the two water bodies is close, and sterilization and disinfection can also be carried out in the process of water crossing.

6. Hide. Black shell shrimp has a necessary growth process, that is, molting, but it is very fragile after molting, so they need a place to hide, and densely planted aquatic plants and stone crevices are the best choices for its shelter.

7. Fertilizer. The black shell shrimp acts as a "cleaner" in the aquatic plant tank, and a variety of trace elements in aquatic weed farming are harmful to the black shell shrimp. Due to the relative lack of nutrients in the waters of the native environment of the black shell shrimp, the trace elements in the aquatic weed fertilizer contain heavy metal components, which will cause the poisoning reaction of the black shell shrimp.

Is it better to raise black shell shrimp in deep or shallow water?

Black shell shrimp is suitable for breeding in deep water, and the water depth of the pond is 2 meters, not suitable for shallow water.

What aquatic weeds are used to raise black-shell shrimp?

As long as it is an aquatic weed, just raising duckweed, other aquatic plants can be, of course, the best aquatic plants are more dense, Moss and other aquatic plants who are liked by black shell shrimp.

They need to live in a shady place.

<> river shrimp is not a black-shelled shrimp. River shrimp are generally shrimp in the river, although the black shell shrimp is a freshwater shrimp and can live in the river, it is still different from river shrimp. Black-shell shrimp can be raised in tap water, but they must be treated first, because there is chlorine in the freshly connected tap water, which is very harmful to the shrimp.

There is no need to put salt in the water in which the black shell shrimp is farmed, because it is a freshwater shrimp and cannot survive in water with high salinity.

1. Is river shrimp a black-shelled shrimp?

1. River shrimp is not a black-shelled shrimp. River shrimp mainly refers to shrimp that live in rivers, while black shell shrimp is a freshwater shrimp, although it can live in rivers, it is not the same thing as river shrimp. River shrimp mainly includes green shrimp, also known as Japanese giant river shrimp, which is a shrimp animal of the long-arm shrimp family, which is different from the black shell shrimp belonging to the spoon finger shrimp family.

2. Black shell shrimp can be cultivated in tap water, but it must not be raised directly with freshly connected tap water, which contains chlorine, which is very harmful to shrimp. In addition, in winter, the temperature of the tap water is relatively low, and the growth of shrimp will also be affected by directly using this water to raise shrimp. Before raising shrimp in tap water, be sure to dry the tap water in the sun for about 2-3 days, and then use it to raise shrimp after the water temperature rises.

3. There is no need to put salt in the tank where the black shell shrimp is raised, because it is a freshwater shrimp and has no way to survive in water with high salinity. Salt is not good for their growth, and if it is for the purpose of disinfection, it is not necessary, generally only need to soak it slightly with low concentration of potassium permanganate or salt water before entering the tank.

2. The difference between river shrimp and black shell shrimp

1. Living environment and food.

1) River shrimp mainly lives in rivers and lakes, and its food is plankton in the water.

2) Black-shell shrimp mainly live in places where aquatic plants are abundant and algae plants are abundant, and their food is algae plants.

2. Body type and color.

River shrimp have one less pair of clawing than black shell shrimp, and the color of river shrimp is the same, and the color of black shell shrimp can change according to the environment.

3. Edibility.

1) River shrimp can be eaten, its meat is very delicious, and it contains astaxanthin.

(2) Black-shell shrimp must not be eaten, and the astaxanthin content in its body is relatively small.

There are some differences between black-shell shrimp and river shrimp in the following three aspects:

1.Living environment: The black sunflower shell shrimp is a freshwater shrimp that can live in freshwater waters such as rivers, ponds, lakes, and streams. River shrimp mainly refers to shrimp that live in the river, which is a type of freshwater shrimp.

2.Species: The black-shelled shrimp belongs to the family Spoon Shrimp, while the river shrimp belongs to the family Long-arm shrimp, and there is a clear difference between the two in terms of species.

3.Feeding requirements: Black shell shrimp can be raised with tap water, but it should be noted that you can't directly use freshly connected tap water, because it contains chlorine, which will affect the growth of shrimp.

At the same time, the tap water that has just been picked up in winter has a low temperature, and direct use for shrimp farming will affect the growth of shrimp. River shrimp, on the other hand, have relatively high requirements for water quality and need to live in clean, oxygen-rich waters.

In conclusion, there are some differences between black shell shrimp and river shrimp in terms of living environment, species and feeding requirements.

1. Black-shell shrimp usually have a larger body size, darker body color, black or dark brown shell, and a flattened abdomen, and generally live in the marine environment, such as deep sea or offshore waters, requiring higher salinity and cold water environment, and black-shell shrimp generally grow on the bottom of rocks or sandy mud substrates, and feed on shellfish, small fish, etc.

2. The remaining potatoes of river shrimp are relatively small, the pants are usually lighter in color, the shell is gray or light yellow, the abdomen is rounder, and they live in freshwater environments, such as rivers, lakes and reservoirs, and feed on aquatic plants, benthic organisms and humus.
