River shrimps are widely distributed in lakes, rivers, reservoirs, ponds and other places in China. The main scientific name of river shrimps is Macrobrachium nipponense, which is a high-quality freshwater shrimp, that is, we often say green shrimp. This name fully embodies the most remarkable feature of river shrimp, that is, the overall color is blue. There are brown stripes on the shrimp, and the shell is thin and soft.
White shrimp, prawn and metapenaeus ensis are the most common marine shrimps. Among them, the shell of white shrimp is very thin, because there are few pigment cells and it is transparent, and it is white after death. The shrimp whiskers of prawns are very long, and the body color is blue and blue. Metapenaeus ensis's body is light brown.
friends who often go to the market to buy shrimps should know that the price of sea shrimps is generally more expensive than that of river shrimps, and Zhou Jun thinks it is the most appropriate to buy them according to the actual situation, and each has its own advantages, and the differences will not be an abyss.
However, because it grows in seawater, the salt content and iodine content of sea shrimp are slightly higher than those of river shrimp. In terms of nutritional value, the protein content of sea shrimp is higher and the unsaturated fatty acids are richer. As for the flavor and taste, the sea shrimp has a fuller taste because it is big and fleshy, but at the same time its fishy smell is quite heavy.
Although river shrimps and sea shrimps have their own merits, there is a real problem in front of us, that is, pollution. Comparatively speaking, the environment polluted by river shrimps is more, and the environment polluted by sea shrimps is better than that of river banks. In a word, the nutritional value of river shrimp is not much different. If you want to have a full and energetic taste, you should eat sea shrimp, but don't deny the flavor of small river shrimp.
