Crayfish is not the shrimp shell the harder the better , crayfish are divided into red shell and green shell, red shell and hard and thick, green shell thin and not very hard. The ideal crayfish is a green shelled shrimp weighing 6 to 8 dollars a piece. Red shell crayfish and green shell crayfish taste difference is not very big, green shell crayfish meat is slightly more tender than red shell crayfish meat, slightly sweeter flavor, but this difference is not obvious, because the green shell crayfish and red shell crayfish is a species.

The decision of the color of crayfish is astaxanthin and astaxanthin, which are two natural pigments. Shrimp with more astaxanthin are red-colored shrimp shells, and shrimp with more astaxanthin will appear green.

If a crayfish is left to grow in the water, the green-shelled shrimp will eventually grow into a red-shelled shrimp. You can understand that the green-shelled shrimp are adolescent crayfish and the red-shelled shrimp are middle-aged and elderly crayfish. Crayfish life to shell about eleven times, shelling during the crayfish are soft-shelled shrimp. Shell change after a short period of time not long after the soft shell becomes hard soon after the green shell shrimp is the best quality crayfish.

Crayfish shrimp shell color is also affected by the water environment , water temperature moderate water quality clean water ponds grow out of most of the crayfish are green shell shrimp, and water quality is poor water ponds in the small thumb long crayfish is also red shell shrimp. Poor water quality in the pond crayfish will reduce the number of shell changes, and will also be the evolution of shrimp pincers larger, because often change the shell means more vulnerable to predators, shrimp pincers small means that they can not be effective self-protection. And clean water environment breeding crayfish without predators, water quality and good, so the crayfish can rest assured that the growth of frequent shell changes, but also do not have to evolve the pincer too big, so good water quality crayfish are green shrimp shells and thin flesh, pincer small does not account for the weight. And those who are young to grow into a red shell crayfish can be said to be the animal world's poor children early to be home without umbrellas for children to run fast.

Buy aquatic products do not be obsessed with buying the so-called permaculture aquatic products, because the wild aquatic products can not guarantee the quality. Buy crayfish you have to buy fresh crayfish farmed in artificial ponds. Many places in the country have crayfish, but can be a year-round supply of green shell crayfish only Jiangsu Huai'an and Hubei Qianjiang.

Crayfish are divided into two parts: the head and tail, we count the head of the crayfish and the gills and thorax as the head, and we eat shrimp mainly shrimp tail, so when picking a crayfish must pay attention to the proportion of the length of the head and tail of the shrimp. Many crayfish are shrimp head longer than shrimp tail, this kind of crayfish weighed and sold to customers is not very cost-effective. Select crayfish with heads and tails that are basically the same length.

Buy crayfish when you look at the crayfish belly and legs are clean , good water quality water ponds to raise out of the crayfish is clean, if the crayfish belly and shrimp legs are more dirty, it shows that the environment of the water pond is not good enough. Eat water goods to eat is the quality of the selection of crayfish to see the shrimp body cleanliness can be roughly know the growth environment of this shrimp.

The biggest advantage of crayfish is that you don't need to be a superb cooking skills can be done not difficult to eat, crayfish pot there is no cooked at a glance, as long as the red is cooked; crayfish do not need to test the knife, do not want to work to prune the whole shrimp can be washed clean and poured into a pot to cook; as for the flavor, there are now a lot of seasoning packages with a lot of good out there, and crayfish to take over A pot of stew on the line.
