The main differences between the monodon shrimp and the basal shrimp are:

1. Different appearance; the monodon shrimp has dark brown and earthy yellow horizontal stripes on its body, and a 7-inch beak on the forehead. ~8 teeth, the lower beak has 2 to 3 teeth, and the lateral grooves of the frontal horn are quite deep, extending to the back of the upper spine of the eye; the base shrimp has a body length of about 8cm, with many depressions on the body surface, and short hairs on them. The forehead is straight and only the upper edge has 7-9 teeth.

2. Different nutritional value. In addition to being the same as ordinary shrimp, the astaxanthin content of monodon shrimp is about 20% higher than that of ordinary shrimp. Astaxanthin is one of the strongest antioxidants. It can significantly enhance the shrimp's survival rate and spawning rate, as well as its ability to withstand harsh external environments. Similarly, humans and animals eating shrimp meat high in astaxanthin can also significantly improve diseases such as atherosclerosis.

3. The production area and production season are different. The distribution area of ??monodon shrimp is very wide, from southern Japan, south Korea, coastal my country, Philippines, Indonesia, Australia, Thailand, India to the eastern coast of Africa. There are two spawning periods in my country's coast every year from February to April and from August to November. The shrimp is native to China, Japan, the Philippines, Malaysia, Indonesia and Australia, and is widely distributed in the coastal waters south of the Shandong Peninsula in my country. May to August is the peak spawning season along my country's coast.

Extended information:

1. Monodon shrimp

Monodon shrimp is the most commonly cultured species in the world. In addition to being the same as ordinary shrimp, it has The content of astaxanthin is about 20% higher than that of ordinary shrimp, so the price is relatively high during the Spring Festival.

Monodon shrimp grows quickly, has strong adaptability, has a variety of feeding habits, has low requirements for protein content in feed (only about 35%), and can tolerate a wide range of salinity and temperature. The salinity range is 0.2~70‰, and the optimal salinity is 10~20‰; the optimal temperature is 25~32℃. Death will occur if it is higher than 38℃ or lower than 14℃. It also has a strong tolerance to hypoxia and can withstand dry dew for a long time, so it is easy to work and transport.

This shrimp is the largest species among shrimps. The largest individual found is 33 centimeters long and weighs 500 to 600 grams. Mature shrimp generally have a body length of 22.5 to 32 centimeters and a weight of 137 to 211 grams. They are valuable shrimps that are very popular among consumers. The nutritional value is similar to other major shrimp species.

2. Jiwei shrimp

New Penaeus prawns are commonly known as mud shrimps, hemp shrimps, flower tiger shrimps, tiger shrimps, sand shrimps, red claw shrimps, and Lu shrimps, and are commercially called Jiwei shrimps.

New Penaeus genus and related New Penaeus are both small and medium-sized economic shrimps. The body length of New Penaeus prawns is generally 7.5 to 16 centimeters, while the body length of New Penaeus prawns is 8 to 15 centimeters. Both types of shrimp weigh 4 to 50 grams. The estuarine sea areas along the coast of Guangdong have higher yields and have fatter bodies and thin shells. They are two species of shrimp with higher economic value among the genus Neopenaeus.

Currently, Guangdong has begun breeding. It can be put on the market after being raised in Hong Kong for about two months. It has a high fishing survival rate and is more resistant to transportation. It is an important species for fishermen in the Pearl River Estuary area to export live shrimp to Hong Kong and Macao. The nutritional value is similar to other shrimps.
