Can you eat crabs all year round? You can eat crabs all year round. Experts from China Ocean University agree with this statement. The breeding of Portunus trituberculatus is not much in Qingdao. From Weihai and Rizhao to Jiangsu and Zhejiang, it is the area where a large number of Portunus trituberculatus are cultivated. "Swimming crabs are mainly cultured in ponds, and a large number of them are listed around August 15 of the lunar calendar," said Professor Ma of Haida University. "But the water temperature in the south is relatively high, so you can raise crabs twice a year, once in spring, and then throw seedlings in July and August in summer. As long as the water temperature is not lower than 0℃, crabs can survive the winter."
Although in this way, citizens can have crabs to eat all year round, but the season when a large number of sea crabs are on the market is concentrated in autumn. After 1 1 month, the number of sea crabs will gradually decrease, and cultured crabs will play the leading role in the market, and with the cold weather, cultured crabs in the south will occupy a larger market.
Do you eat crabs all year round? At the end of September-before the Spring Festival: Yangtze crabs, nine females and ten males are the most suitable.
Every year when the autumn wind is cool, it is the time when hairy crabs flood on the tip of diners' tongues. Wang Chenghui said that the crab migration season (from cold dew to 1 1 early month) is the best season to eat crabs. The crab meat at this time is thick, tender, delicious and fragrant, and it is the most delicious in a year. And this period is the mature eating period of the Yangtze River crab in China.
The Yangtze River basin is the main crab producing area in China, such as the famous Yangcheng Lake hairy crab, Qidong crab, Taihu crab and Subei crab, all of which belong to the Yangtze River crab. Hairy crabs will undergo multiple molting and growth in their lifetime, and Yangtze crabs will be listed one after another at the end of September. Eating crabs in autumn requires distinguishing between males and females to enjoy the most delicious crab feast in this season. The so-called "nine females and ten males" means that the females are the fattest in September of the lunar calendar, and the crabs are yellow and firm. In October of the lunar calendar, the males are the most fragrant and full of crab paste, and it is best to eat crabs and enjoy chrysanthemums.
Spring Festival-end of April: hairy crabs are temporarily raised, and the taste and nutrition are difficult to guarantee.
In order to realize people's desire to eat crabs all year round, temporary breeding of hairy crabs appears, that is, some mature hairy crabs in autumn are temporarily raised in a specific low temperature environment through science and technology, and then marketed out of season, so as to solve the suffering of crab lovers.
It is difficult to temporarily raise hairy crabs, which not only has market risks but also faces technical difficulties. Wang Chenghui said that hairy crabs are easy to lose weight. If the breeding environment is not good, the quality of crabs will be affected, the taste will become worse, the crab paste will become hard, the crab yolk will become less, and the nutrients will be lost. In order to maintain the taste, farmers need to strengthen the provision of animal bait, and at the same time, they can take the way of cooling to delay the development of crab gonads, "so that energy and nutrition can be preserved for a longer time." Crabs are temporarily raised in the wrong season, so crab hoarders usually wait for the sale of temporary crabs after the Spring Festival, so that hairy crabs can be served on the table in spring.
From the end of April to mid-June: wild hairy crabs from Russia and North Korea, and the best tasting period is short.
You may not think that at this time, crabs are not green and yellow. With the prosperity of border trade, wild border trade crabs from Russia and North Korea have crossed geographical restrictions and appeared on the dining tables of Chinese diners. According to experts, Russian and Korean hairy crabs have flat frontal teeth (four teeth) compared with Chinese hairy crabs in the Yangtze River valley, which belong to the pure wild environment. Without any artificial breeding, the growth environment is difficult to guarantee, so the taste is different every year.
Due to the high latitude and low temperature, the wild hairy crabs in Russia and North Korea will not reach full maturity until the third year, so the yield is extremely low, and crabs have the habit of reproductive migration. The hairy crabs in Russia and North Korea migrate from the end of April to the middle of June, and the best tasting period is short, so we must try it in that season.
From mid-June to the end of August: June is yellow with thin shell and fresh meat.
"Be busy, don't forget June Yellow", a folk proverb, is a compliment of diners to June Yellow. June Yellow is a "small fresh meat" in hairy crabs, also known as "boy crab". It is a hairy crab in adolescence, and it is often listed in mid-June every year.
Wang Chenghui said that June Yellow is called "green crab", which has the characteristics of small size (generally weighing about 2 Liang), thin and crisp shell, delicious taste, heavy fishy smell and less limb meat, so it can be tasted in this short crab eating season. Male crabs were mainly eaten during this period, and the female crabs at this time were still very small, about one or two, which was not suitable for eating. Because he is still a "minor", there is no crab paste in June yellow, only crab yellow. Although it is not as big as an adult hairy crab, it is different from the hard crab yellow of adult hairy crabs. The crab yellow in June is delicious and fat. Pick the crab yellow with swollen body and yellow belly, and make "noodles dragging June yellow" and "fried rice cakes with June yellow" to solve the problem.
From the end of August to the end of September: Liaohe crab, slightly smaller.
Liaohe crab and Yangtze crab belong to the same river crab, Yangtze crab is a southern crab, and Liaohe crab is often said to be a northern crab. According to the law of reproduction and migration of Liaohe crabs and the local climate characteristics, Liaohe crabs have been listed one after another at the end of August, and September is the peak of fishing.
Under normal circumstances, the Liaohe crab is smaller than the Yangtze crab, because the temperature in the Yangtze River basin makes the Yangtze crab shed its shell more than the Liaohe crab once a year, which means it grows again. However, in recent years, in order to pursue the growth of Liaohe crab, many farmers will keep some crabs for 2~3 years before fishing and selling, and the specifications can also be compared with those of Yangtze crab. According to experts, as long as the breeding environment of crabs is high-quality, the aquatic products are abundant, the water quality is clear, and there are many animal feeds, Liaohe crabs can also become high-quality hairy crabs with green shells and white bellies and golden claws and yellow hair.
When is the best time to eat crabs? Although crabs are eaten all year round, autumn is the best season to eat crabs. It is said that "the autumn wind starts, and the crab's feet itch; Chrysanthemum blossoms, smell crabs ",and every September 9~ 10/October is the time when crabs are yellow and full of oil, so some foodies say that" eating crabs is the most solemn thing in autumn ".
It is said that autumn is the season to eat crabs, because the season has a great relationship with the growth quality of crabs. Autumn is the best time for crabs to grow. Their meat is thick, fat and tender, and delicious, which is the most delicious in a year. What kind of cream crabs, meat crabs, hairy crabs, etc. all grow best in autumn. In particular, "Yang Orange Lake Hairy Crab" is tender in meat, creamy in paste, delicious in taste, and of high value.
In the case of hairy crabs, as the saying goes, there are nine females and ten males, that is to say, it should be the time to eat female crabs in September of the lunar calendar. At that time, the yellow of female crabs was full of sweetness. October of the lunar calendar should be the time to eat male crabs, which are full of cream and rich in nutrition.
Sea crabs are usually eaten in cold weather. At that time, crabs need to eat more to make themselves fuller to survive the cold, so the colder the weather, the more they eat crabs ~
When crabs are fattest As the saying goes, "Autumn comes, crabs are fragrant". Autumn is the most vigorous period for crabs to grow, and the crab meat at this time is the most plump and delicious. From August 15th to November 15th, it is a good time to eat crabs, and the fattest one is around September 15th. At this time, crabs in fresh water are the best, and those in the sea are also good.
Eating crabs is the most solemn thing in autumn. This season, it is also the most fat time for sea crabs. They are big and thick with crab pincers. The glistening crab meat has a natural salty flavor, and with the red and thick paste, you don't need to put any seasoning. When you steam it on the pot, the fragrance will not be lost to Yangcheng Lake hairy crabs!
