Boston lobsters can only mate for a short time after shelling. Shelling occurs about 2-3 times a year in childhood, and every year/kloc-0 times in adulthood (4-7 years old). Boston lobster lives in the cold sea below 600~700 meters. After leaving the water, its life span is short and its growth is very slow. Most of the Boston lobsters caught are 0.5~ 1 kg, a Boston lobster is about 7 ~ 10 years old and one kilogram (about 453 grams), and a Boston lobster of 6 ~ 7 kilograms is equivalent to growing for nearly a hundred years, so it is called "century-old lobster" and has a long life. The older the lobster, the more nutritious it is. Zheng Yuntao, general manager of the big fishing ground, said in an interview that because lobster grows slowly, the older it is, the more nutritious it is and the more delicious it tastes.
