The Japanese forced fishermen to sell all of their catch to the fishermen's association, which in turn gave most of it to the army. As civilians could only get very little meat through ration coupons, some fishermen would hide fish in their boats, dry them, and sell them on the black market.
當時規定漁獲全部交由漁會收購，以供給大量駐軍，由於民眾只能持配給券領到極少的肉類，有些漁民便在船艙中偷偷藏魚，曬成魚乾後，夜裡摸黑「走私」運出販賣。
