In 1983, a small island started from a large farmer

Introduction: Returning to the small island in 1983, Li Duoyu picked up a net of large yellow croaker. He thought he could make a lot of money, but he was slapped in the face because in this era, the purchase price of a pound of large yellow croaker was only four yuan. hair. In this era when seafood was difficult to produce, Li Duoyu took the lead in starting the aquaculture industry that was least optimistic about at the time. (My parents are short-sighted. They focus on mariculture. They raise kelp first, then abalone, eel, blue crab... The background of the story is purely fictitious. If there are any similarities, it may be true.)
