TAIPEI (Taiwan News) — When a fisherman in Kaohsiung looked at his catch of the day, he found an undetonated explosive, reports said Friday (Jan. 22).

The catch likely occurred just 5 nautical miles off the coast of Kaohsiung's Zuoying, one of Taiwan’s primary naval bases, according to the Liberty Times.

The fisherman only realized what he had found when he was unloading his cargo of fish at a port in Kaohsiung Thursday morning (Jan. 21). He immediately called the Coast Guard Administration, which sent a team over to inspect the unusual find.

The experts concluded the barrel-like object was an MK6 depth charge and closed off the fish market, limiting access for visitors and vehicles. They also called in a bomb disposal unit from the Army.

As the explosive was deemed not to pose any immediate risk, the unit brought it back to the local Army base for further examination, and the fish market reopened for business, the Liberty Times reported.
