Boston lobsters can only mate for a short time after shelling. Shelling occurs about 2-3 times a year in childhood and once a year in adulthood (4-7 years old). Living in the cold sea below 600~700 meters, Boston lobster has a short life span after leaving the water and grows very slowly. Most of the Boston lobsters caught are 0.5~ 1 kg, a Boston lobster is about 7 ~10 and grows a pound (about 453 grams), while a Boston lobster of 6 ~ 7 kg is equivalent to growing for nearly a hundred years, so it is called "century-old lobster" and its life span is quite long. The older the lobster, the richer the nutrition. 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 is.
