In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia  Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9, 000 tons below pre-1992 levels
It is ttherefore highly likely that the outlaw fishing boats harvested about 9, 000 tons of lobster illegally that year
Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats.
