HIPPO EXCREMENT TRIGGERING FISH KILLS IN AFRICAN RIVERS

“Periodic intense rains eventually flush the water downstream. This sudden pulse of deoxygenated water can cause temporary hypoxia and fish kills.” Over three years, scientists monitored water chemistry downstream from 171 hippo pools. During that time, scientists observed 55 flushing events, when rains doubled the river’s volume.

“Periodic intense rains eventually flush the water downstream. This sudden pulse of deoxygenated water can cause temporary hypoxia and fish kills.” According to the study published Wednesday in the journal Nature, the researchers monitored 171 hippo pools in the reserve and observed 55 rain-driven flushing events.

This explained the fish kills. The next step was to find the cause, which led them to investigate the effects that the hippos in the region might be having on the water. What they found was that the 4,000 or so hippos in the Mara River excreted about 8,500 kg of feces daily.
