Hello, my friend, how much money you can earn by raising sea cucumbers in a year depends on the price of sea cucumbers in the current season, the breeding area, whether the breeding technology is mature (whether the sea cucumbers are raised well or not) and other specific circumstances. Some people earn tens of millions, while others lose money to jump into the sea (this is true). In any industry, there are gains and losses, especially in aquaculture. There are too many unstable factors. If you want to raise sea cucumbers, I suggest that you don't say how much money you can earn, but first know how much risk you can bear.

I wish all the best!
