You do get the sense that there hasn't been a fish in North Korea for the best part of a decade but one does wish their soldiers would be more careful:

A midday incursion Saturday by North Korean troops into the southern side of the no-man's-land separating North and South Korea only stoked the unease. South Korean soldiers rattled off 40 warning shots at the five communist troops who crossed the centre line of the Demilitarized Zone, the inter-Korean buffer. It was unclear whether the North Korean advance was intended as a provocation, or was an attempt to go fishing at a nearby stream, an official at South Korea's Joint Chiefs of Staff said on condition of anonymity, citing official policy. No one was hurt, and the North Koreans retreated.
