Fishing methods include drift net, middle trawl with wheels and hook fishing.
In the 1950s and 1960s when resources were abundant, it was a good season to catch Spanish mackerel in Bohai Bay from May to June. When the sun touched the mountain, the net floated and the awn stretched for more than ten miles. From the next morning, there were often three or four thousand fish weighing three or four kilograms.

Its streamlined shape, extremely high swimming speed and sharp teeth are like cheetahs chasing prey, and frightened small fish are fleeing everywhere, often rushing to the shore reef to "get out of the row", which surprises the spectacular scene of Spanish mackerel flying to catch food.
