A fish monger sells tilapia at an open air market in Nairobi, April 30, 2008. The price of fish has risen after the post-election violence from 120 Kenyan shillings to 250 Kenyan shillings ($1.9 - 4) per tilapia, a fish monger said. Global food shortages and higher prices are more likely to cause malnutrition than outright famine, at least in the near-term, the coordinator of a new United Nations task force said on Wednesday.
