What is the longest lived shrimp in the world?

The world's longest-lived shrimp is the lobster, and the longest surviving shrimp has reached 130 years of age. And lobsters have a strong reproductive ability.

The longest-lived shrimp in the world is the lobster, the longest-lived lobster has survived for more than 130 years, named Louie, after measuring it weighs 20 catties, the body length has reached an astonishing meter, has reached the tonnage of giant lobster.

The world's longest-lived shrimp should be the freshwater shrimp because it lives in freshwater and absorbs the nutrients in freshwater.

The largest shrimp in the world is the giant river prawn.

The world's largest freshwater shrimp is giant river prawn, which is native to Southeast Asia and is concentrated in some countries including Thailand and Myanmar.

One of the distinctive physical features of giant river prawn is that their heads are very large, very disproportionate to their bodies, and they look very incongruous, so they are highly recognizable. The male giant river prawn also has a distinctive foot, with the second leg being up to 40 cm long.

Habitat of giant river prawn:

Giant river prawn live in freshwater from juvenile to adult stage, mature broodstock mate in freshwater, hold eggs, discharge seedlings in saltwater, and larvae develop in saltwater.

Giant river prawn has higher requirements for dissolved oxygen content in the water, is not tolerant to fertilizer water, generally requires dissolved oxygen content of more than 5 milliliters, and the dissolved oxygen concentration has a great impact on shrimp feeding growth and feed efficiency, especially in the middle and late stages of breeding, the water should be changed frequently, and the transparency of the water is kept between 35 and 40 cm.

The lifespan of shrimp is only a little more than 1 year.

Generally, the shrimp fry hatched in one month will die one after another after completing the task of breeding the next generation in the next month.

Shrimp is an arthropod that lives in water.

It belongs to the arthropod crustaceans, and there are many species, including Antarctic red shrimp, green shrimp, and river shrimp.

Grass shrimp, prawns, prawns.

Lobster, etc. Shrimp has a high therapeutic nutritional value, can be steamed, fried and other practices, and can be used as Chinese herbal medicine.

Growth environment: Shrimp swimming is very different from fish, fish can swim forward by swinging the tail fin, while shrimp does not have a tail fin like a fish, only a tail and many lower legs, shrimp also has its "high tricks". Shrimp are expert swimmers and can swim long distances with their legs.

When it swims, those swimming feet are like wooden paddles and frequently and neatly row backwards, and the body is slowly driven. When frightened, its belly flexes and stretches nimbly, and its tail strokes down and forward, and it can jump backwards continuously, and it is very fast. Some shrimp are not good swimmers, and large lobsters crawl on the sand and rocks on the bottom of the sea most of the time.

The gills of the shrimp are located in the gill chamber formed on both sides of the dorsal carapace, and the anterior and posterior gill chambers and the ventral surface communicate with the outside world, and the gills are mostly feathery, with a total of 25 pairs.

If all the conditions are met, you can live for a year and a half! In terms of breeding, it is about 1 litter a month, but it is not a harvest that is harvested in 12 months a year! My advice for feed is:

It's OK if it's nutritious!Vegetables, dry fodder, you can do it! Don't worry too much!

Don't be too squeamish with shrimp! But for crystal shrimp, the feed still needs to be paid attention to! He's about the performance of the shrimp!

Trouble, thanks!

There are also wild ones that live up to 2 to 3 years.

The shrimp that are easier to raise are black shell shrimp, cherry blossom shrimp, crystal shrimp, flame shrimp, polar fire shrimp, ** rice shrimp, etc., and some artificially cultivated shrimp can also be cultivated. These kinds of shrimp do not have high requirements for the environment, and the ability to adapt is relatively strong, which is very suitable for breeding as ornamental shrimp. The vitality of the crayfish is tenacious, the difficulty of raising is low, and there are many kinds of colors, which is also more suitable as an ornamental shrimp.

With the exception of crayfish, these shrimp can be polycultured with fish or other aquatic animals because of their gentle nature, small size, and ability to clean algae and moss.

The largest sea shrimp in the world is the American crayfish, and the largest shrimp in the world is the ghost shrimp.

1. American crayfish.

The American crayfish, also known as the Boston lobster, is now the largest shrimp in the world. The largest of them is a Boston lobster, which weighs a staggering kilogram, and its total length is even more than a meter from the tail to the tip of the large claw. Boston lobsters are found on the North American coast of the Atlantic Ocean, Canada, Newfoundland, Labrador, Maine and Massachusetts in the United States, and feed mainly on fish and shellfish.

2. Ghost shrimp. Ghost shrimp generally refers to the giant shrimp, the largest of the shrimp, according to the record shows that the largest individual is 33 centimeters long and weighs 500 600 grams. Compared with ordinary shrimp, the size of ghost shrimp is more than 10 times more.

Ghost shrimp has a wide distribution area, from the southern part of Japan, South Korea, the coast of China, the Philippines, Indonesia, Australia, Thailand, India to the eastern coast of Africa.

The habits of crayfish and ghost shrimp

1. American crayfish.

The crayfish lives in shallow reefs or burrows in the gravel bottom, and feeds on fish, other small crustaceans and shellfish, and occasionally marine plants. Natural predators include cod, flounder and other dragon prawns.

American crayfish can only mate for a short time after shedding their shells. It is shelled about 2-3 times a year in childhood and about once a year in adulthood (4-7 years old). Because they live in cold waters below 600-700 meters, Boston lobsters have a short survival time after being out of the water and grow particularly slowly.

2. Ghost shrimp. Ghost shrimp usually lie dormant on the soles of the sea or in the mud and sand during the day, and begin to move in the evening. This species has a wide range of salinity adaptation, ranging from 10 to 35.

Adaptation to water temperature ranges from 14-32. The catch was higher in the range of 22-25 and 20-34 with a bottom salt. Ghost shrimp is judged to be a widely saline species, which has a great tolerance to salinity changes, and can live normally in the salinity range of 11-33.

<> male shrimp generally has a lifespan of 20 months, and female shrimp has a lifespan of 24 months. It takes about 1 month for river shrimp to grow from spawning to seedlings, and it takes 45 days to grow to adult shrimp, about 80 fish 1 catty, and about 20 fish 1 catty for 90 days. Generally, in late May, when the water temperature is stable at 18-20, shrimp seedlings can be stocked, and shrimp seedlings should be desalination after more than 1 week, and there is no need to feed bait in the pond in January.

1. How long do river shrimp live.

1. The life span of male shrimp is 20 months, that is, 1 year and 8 months, the life span of female shrimp is 24 months, that is, 2 years, and it takes 1 month for river shrimp to spawn to seedlings, and it takes 45 days to grow to adult shrimp, about 80 catty, and about 20 catty for 90 days.

2. River shrimp is widely distributed in lakes, rivers, reservoirs and ponds in China, also known as green shrimp, the scientific name is Japanese giant shrimp, it is a high-quality freshwater shrimp, river shrimp is nutritious, and the meat is soft, easy to digest, and it is a good food for people who are weak and need to recuperate after illness.

Second, the cultivation technology of river shrimp.

1. Pond conditions.

You can choose a freshwater pond or shrimp pond with an area of 3-5 acres, a water depth, sufficient freshwater source, no pollution, and a sandy bottom.

2. Fertilize and bait.

7 days before the stocking of shrimp seedlings, it can be filtered with 60-80 mesh sieve silk, 30cm of water, and 50kg of base fertilizer (fermented animal manure) or 5kg of urea per mu to cultivate basic bait.

3. Shrimp fry stocking.

Generally in late May, when the water temperature is stable at 18-20, shrimp seedlings can be stocked, shrimp seedlings need to be desalination treatment for more than 7 days, and the specific gravity can be stocked below, generally 3-40,000 shrimp seedlings per mu, the following seedlings need to be temporarily raised, and the shrimp pond can be polycultured 10-20cm silver carp fingerlings 80-150.

4. Feed feeding.

Shrimp seedlings in the pond generally do not need to be fed with bait within 1 month, mainly rely on plankton in the pond for food, 1 month after feeding with bait, supplemented by fresh fish and shellfish, etc., the feeding rate is generally 3%-5% of the weight of shrimp, in 7-9 months can appropriately increase the amount of bait, it is advisable to leave no residual bait, the number of bait is 2-3 times a day, the amount of daytime feeding accounts for 1 3, and the night is 2 3.

5. Water diversion and disease prevention.

After 10 days of stocking of shrimp seedlings, water needs to be added gradually, 10-15cm per week, 20-30cm of water every 2-3 days in the high temperature season, every 15 days or so, 5-10kg of quicklime slurry per mu is sprinkled throughout the pool, which not only improves water quality and substrate, but also can sterilize and promote hulling growth, and at the same time 15-20 days, it is necessary to mix 1%-3% garlic bait, and cast it for 3-5 days.

6. Arrest. Generally 80-100 days of breeding, the shrimp body up to 7-10cm can be caught according to the market, can be caught with nets or released water, 36 hours out of the water dry work, survival rate can be as high as 90%.

In the past, it was generally believed that the lifespan of small shrimp was 2 to 3 years, and it was also said that it was 7 to 8 years. In fact, the lifespan of green shrimp is only a little more than 1 year. Generally, the shrimp fry hatched in one month will die one after another after completing the task of breeding the next generation in the next month.

Live for a long time and see what kind of shrimp it is, lobster. Hehe. A lot of it was eaten! I could have lived!

Generally, shrimp can live for a few years regardless of it.
