Chinese media reported that farming of longxucai and other seaweeds is boosting fishers' incomes along China's coast, with 'sea ranch'-style aquaculture spreading.

Seaweed farming can start at relatively low cost and has wide uses—food, feed and industrial inputs—drawing notice as a way to add value in fishing villages.

Aquaculture is seen as able to pair conservation with higher incomes, though water quality and avoiding over-farming pose sustainability challenges.

Coastal farming's spread also matters for food supply and diversifying local economies.
