The fishing industry started with the first wave of Chinese immigrants, attracted to the area by the availability of abundant fishing. The town's heyday came under the jurisdiction of the Dutch East Indies, around 1930, when the fisheries produced 300,000 tons of fish per year. The annual production has fallen since, being particularly affected by a collapse of fish numbers since the 1970s, by which time over 800 trawlers based in the town were fishing the Shunda Shelf. The trawling ban in Indonesian waters, introduced in 1980, has had a significant effect on the economy of the town.
