CATDOLL : CATDOLL: How to raise shrimps and how long can shrimps be raised?

1. How to raise shrimps and how long can shrimps be raised?

1. When raising shrimp, you must build a pond in a place with sufficient water. The water depth should be about 2-5 meters. Water inlet and outlet channels should be installed in it to facilitate irrigation and drainage, and to prevent the invasion of harmful organisms.

2. Before breeding, you need to clean the pond first. Generally, bleaching powder is sprayed throughout the pond. Then you need to cultivate basic bait and apply fertilizer to the water to promote the reproduction of plankton. After that, you can release the shrimp fry.

2. How to breed shrimp?

The shrimps are used to lurking in the bottom mud and water plants. The rice fields are required to be close to the upper and lower water channels, with sufficient water sources, good water quality, smooth drainage and irrigation, and convenient transportation.

The risk of breeding shrimp in rice fields is relatively high. The main technical problem is the dilution of seedlings. When purchasing seedlings, you must choose dilute seedlings to avoid affecting the quality and survival rate of shrimp. It is difficult to adapt to the large-scale rice field environment. It is best to grow them in temporary fields until they are 2-3 cm in size before releasing them into rice fields.

The upper and lower water outlets must be tied tightly with screens, and wild fish or fish eggs are strictly prohibited from entering the fields to prevent small fish from competing for food and big fish from eating shrimp, thus affecting the yield per unit area.

Introduction: Metapenaeus ensis is also known as "basic shrimp" and "unicorn shrimp". It belongs to the class of soft armor and the family of Penaeidae. It is about 8cm long. There are many concave parts on the body surface, which are covered with short hairs. The forehead is straight, with only 7-9 teeth on the upper edge. The cephalothorax has obvious cardiobranchial grooves and cardiobranchial ridges, obvious hepatic grooves, hepatic spines, antennal spines and supra-ocular spines, and no cheek spines. The first three pairs of walking legs have basal spines, the first leg has a sacral spine, the fifth walking leg has no external limbs, the seventh thoracic segment has lateral gills, and the third jaw has no limb gills. It is an important economic species and is the object of artificial breeding.

1. The shrimps are used to lurking in the bottom mud and water plants. The rice fields are required to be close to the upper and lower water channels, with sufficient water sources, good water quality, smooth drainage and irrigation, and convenient transportation.

2. After the shrimp fry are put into the field, they mainly feed on plankton in the rice fields. One month later, when the shrimp fry grows to 2-3 cm, they are mainly fed with fine artificial compound shrimp bait, with the daily feed amount being 5%-6% of the shrimp body weight; when the water temperature reaches 24-30℃, the shrimps eat vigorously, and the daily feed can be increased to 8%-10%. Feed 3-4 times a day, of which 40% of the daily feed is fed in the evening. In places with conditions, plankton and wild fish can also be collected as supplementary feed. It is best for the shrimp to eat all the food within 2-3 hours each time.

3. The water level in the early stage of shrimp breeding should be kept at about 5 cm. The water level in the middle stage should not be lower than 10 cm. The water quality should be fresh and moderate in fertility. The transparency of the shrimp breeding ditch should be between 35-40 cm, and the water color should be light green.

4. The risk of breeding shrimp in rice fields is relatively high. The main technical problem is the dilution of seedlings. When purchasing seedlings, you must choose dilute seedlings to avoid affecting the quality and survival rate of shrimp. It is difficult for shrimp to adapt to large-scale rice fields. It is best to grow them in temporary fields until they are 2-3 cm in size before releasing them into rice fields.

5. The upper and lower water outlets must be tied tightly with screens. Wild fish or fish eggs are strictly prohibited from entering the fields to prevent small fish from competing for food and big fish from eating shrimp, which will affect the yield per unit area.

1. The living habits of the shrimp

Wide-temperature and wide-salinity shrimp. Widely inhabits sandy, sandy muddy and muddy sea areas. It is distributed in coastal areas within a depth range of 50 meters, and its number is larger within 10 meters. The water temperature range of the blade-headed shrimp is very wide. It is distributed in the sea area of ​​8-29°C. The water temperature for breeding is preferably 18-25°C. The blade-headed shrimp is a wide-salinity species, and the salinity range can be between 0‰ and 34‰. It has a very mixed diet, mainly preying on benthic organisms, and also eating bottom plankton and swimming organisms.

2. The production and season of mud shrimp

It is native to China, Japan, the Philippines, Malaysia, Indonesia and Australia. It is mainly distributed in the east coast of Japan, the East China Sea and the South China Sea, the Philippines, Malaysia, Indonesia and Australia. In my country, it is widely distributed in the coastal waters south of the Shandong Peninsula. It is also distributed in the Philippines, Malaysia, Indonesia and Australia. The peak spawning period along the coast of my country is from May to August.

3. What is the culture of mud shrimp?

1. Site selection: The breeding site is similar to the site for raising other fish and shrimp.

2. You can build a pond yourself or use a rural pond, which should be 2-5 mu in size and 1-2 meters deep.

3. The pond should have some slope and be slightly inclined to facilitate drainage.

4. Fertilization and bait cultivation. The shrimp feed on plankton, so it is necessary to fertilize and raise bait about a week after stocking.

5. The basic biological bait in the shrimp pond is mainly organic fertilizer and inorganic fertilizer.

6. Stocking: The best growth environment for shrimp is water temperature between 18 and 30 degrees.

7. Therefore, the seedlings are usually planted around late May, when the temperature is relatively stable, which is suitable for planting.

8. Breeding management: after the shrimp fry enter the pond, daily management begins.

9. The main tasks are water quality, feeding, disease prevention and control management, etc. Water quality management is extremely important.

4. How long does it take for dead shrimp to become inedible? How to keep them after buying them home?

Dead shrimps should not be eaten after nine hours of death, and the same applies to dead crabs. Of course, to be on the safe side, it is best to eat the shrimps within two hours of death. After all, it is better to eat fresh seafood. I have tried to keep shrimps in a pond before, changing the water every once in a while, and they survived for an afternoon. Shrimp are difficult to keep alive. If you just want them to live a few more hours, keep them in water and change the water regularly (about half an hour). It is still recommended to buy and eat them now☆

Buy the shrimp and raise them in water at home. Add ice cubes to the water and then use an oxygenator to oxygenate the water.
