A Detailed Explanation of the Five Major Differences Between Kuruma Shrimp and Greasyback Shrimp

Friends who enjoy eating shrimp and those who make money farming shrimp will certainly compare and study all kinds of shrimp. Aside from crayfish, which are easy to tell apart, many people have trouble distinguishing between kuruma shrimp and greasyback shrimp, because they look somewhat similar. So today, the editor has put together five major points to analyze exactly where their differences lie!

1. Differences in scientific names

1. The scientific name of the kuruma shrimp is Marsupenaeus japonicus (Japanese tiger prawn), belonging to the crustacean genus Penaeus. Smaller shrimp are called shrimp coins. The name also changes from region to region; in some places it is called flower shrimp, flower-tail shrimp, banded shrimp, or kuruma prawn.

2. Greasyback shrimp is a commercial name; its scientific name is Metapenaeus ensis (greasyback shrimp), belonging to the arthropods. In some places it is commonly called mud shrimp, hemp shrimp, tiger shrimp, sand shrimp, or red-claw shrimp.

2. Differences in body shape and color

1. The body surface of the kuruma shrimp is pale yellow, with blue-brown horizontal striped patterns. The tip of the tail is bright blue. The shell is relatively hard. The rostrum looks like a curved bow. The body size is quite large; the common single weight on the market is about half a liang to one liang.

2. The shell of the greasyback shrimp is relatively thin. Juvenile shrimp are dark green to deep green in color, while adult shrimp are light brownish-yellow, with the body densely covered in light brown dots. The greasyback shrimp is generally about the size of a middle finger, not as large as the kuruma shrimp.

3. Differences in place of origin

1. The kuruma shrimp is mainly distributed in China's coastal cities. In China's coastal cities, January to March and September to October are the two best periods for catching adult shrimp.

2. The greasyback shrimp is mainly distributed in the area south of the Shandong Peninsula in China as well as in Guangdong Province. Each year, May to August is the best period for catching it. It is an excellent variety for raising sea shrimp in fresh water.

4. Differences in ecological habits

1. The kuruma shrimp likes to inhabit sea areas with a water depth of 10-40 m. During the day it hides in the sandy bottom, and at night it goes out to move about and forage. The optimal suitable temperature is 25-30 degrees. The most suitable salinity is 25-30. It mainly likes to eat small invertebrates and plankton.

2. The greasyback shrimp likes to inhabit sea areas with sandy bottoms, sandy-mud bottoms, and mud bottoms. Within 10 m of the coast, many greasyback shrimp can be found. The optimal suitable temperature is 8-29 degrees. If artificially farmed, the water temperature only needs to be controlled at 18-25 degrees. The most suitable salinity range is between 0‰-34‰. It mainly likes to eat benthic organisms, with plankton as a supplement.

5. Differences in economic value

1. The kuruma shrimp is Japan's most important farmed species. It is generally sold when it reaches a size of 25 grams. Usually, after 6 months of farming, it can enter the market for sale. It is also one of China's important farmed species. The profit from selling it on the market is also relatively high, and it is generally sold by the piece.

2. The greasyback shrimp is the main product of China's coastal cities in Guangdong. Artificial farming has now begun on a wide scale in the Guangdong region. The farming time is relatively short; generally, after 2 months of farming, it can be sold. After being caught, its survival rate is high, and it is relatively tolerant of transport. It is a good helper for fishermen to get rich, and on the market it is generally sold by the jin.

In summary, the above are the differences in taboo value between kuruma shrimp and greasyback shrimp. Farmers can choose which species to farm based on the temperature in their region to make money.
