Why is small yellow croaker also called plum fish?

Small yellow croaker is also called plum fish, because the fishing season (concentrated fishing season) of small yellow croaker formed in Zhoushan fishing ground in Zhejiang Province along the East China Sea is when plums are ripe, so it is called "plum fish". Nowadays, due to overfishing and coastal pollution, the fishing season of small yellow croaker has long since ceased to exist. What a pity!
