1. Choose to buy in peak season. Generally speaking, autumn is the high-yield period of crabs, and crabs at this time are more fleshy and plump. Therefore, if conditions permit, it is the best choice to buy crabs from September to 165438+ 10 in autumn.
During this period, the temperature is moderate and the temperature difference between day and night is large, which is conducive to the rapid growth of crabs. The food sources in autumn are also very rich, so small crabs can eat more bait. At the same time, the autumn climate is mild, crabs have vigorous metabolism and fat meat. In winter, crabs enter a semi-hibernation state, their growth rate slows down and their meat quality deteriorates. Therefore, autumn is the harvest season of crabs. If you choose this season to buy, you can buy crabs with the best meat quality.
2. Choose a lively one. When buying crabs, choose agile and lively crabs in cages. This shows that it is still full of vitality, with keen nerve response and more freshness. If crabs are inherently weak, even if they are fed, they are not delicious.
The lively crab shows that it is full of energy, sensitive to external stimuli and in good nerve and muscle condition. This powerful jump needs energy, so an active crab also means that it has enough food to eat recently and has stored enough nutrition and energy. On the contrary, if the crab is too weak to jump, it means that it is old or sick. Even if it is fed, its meat quality and taste will not be too good. So it is very important to choose the active crab.
3. Look at the appearance of the shell. Choose crabs with shiny shells and bright colors. The shell surface is clean, and there are not many attached algae, indicating that the water where it grows is clean, and the food this crab eats is cleaner.
I pay special attention to their shells when I buy crabs myself. Generally, crabs with smooth and shiny shells and bright red colors are the best. This means that the water it grows in is clean, and there are not too many impurities sticking to the shell. On the contrary, if the shell surface is dull or there are many algae and aquatic plants, it means that the water where it grows is dirty and the food it eats will be polluted, so the crab is not so delicious. I suggest that you should carefully check the appearance of the shell when buying crabs. The smooth and clean shell can ensure a clean food source for crabs.
4. Both male and female crabs are selected. Generally speaking, male crabs are bigger and have more meat, but female crabs have more tender meat. You can choose a male crab or a female crab according to your personal taste.
In fact, the biggest difference between male crabs and female crabs lies in their size. Male crabs are bigger and stronger, and their claws are bigger, so the overall meat quantity will be more. But the female crab is smaller and the meat will be tender. If you want to eat more crab meat, you can choose male crab. However, if you want to eat crabs with more delicate taste, it is recommended to choose female crabs. This needs to be decided according to personal taste. I prefer female crabs myself. Although there is less meat, the tenderness of the meat gives me an appetite.
5. Look at the color. The flesh color of crabs can also judge their freshness. In general, it is best to be white in color. If the flesh is yellow, it means that this crab has aged; The reddish color is "water crab", which means that it dies after soaking in water for a period of time. This crab is not very fresh.
I once bought crabs with reddish flesh, but the taste was not delicious enough. So I suggest you choose a white crab that looks crystal clear, so as to ensure its freshness. Don't buy yellow or red meat with shells. These are not very fresh signals.
6. Look at your eyes. The eyes are prominent and energetic, and the surrounding green space is small and fresh. Depressed eyes indicate aging. I suggest you pay attention to the eyes of crabs when you buy them. If the eyes are still prominent and there is a god, the surrounding green area is very small, indicating that this crab is still relatively young. On the other hand, if the eye socket is sunken and the surrounding green circle is large, it means that this crab is old.
Because with the growth of crab age, the eyes will gradually shrink and sag, and the green area will become larger. Therefore, the freshness of crabs can be preliminarily judged by observing the state of eyes. Relatively speaking, prominent eyes are a better choice. This is also a detail that I pay attention to every time I buy crabs.
