The Risks for Fish - Episode 10
from The Loop, C-IMAGE Research Hosted by David Levin
When when an oil spill occurs, it's extremly hard to figure out which major commercial fish species are at risk. A team of scientists at the Mote Marine Laboratory hope to find out, however. At a facility 20 miles inland from the coast of Florida, they're growing adult fish—some of which are up to four feet long—in a series of huge tanks, and are slowly exposing them to oil. They're hoping their experients will show them how various species are affected by oil, both in the short term and the long term. If chemicals in oil affect their genes or their breeding, they say, the future of those species could be at risk.

What this episode covers
What happened to the fish in the days and weeks after the oil spill? With a suite of exposure studies, C-IMAGE researchers are monitoring fish health after oil exposure in order to find out. Dr. Dana Wetzel and Kevan Main of Mote Marine Laboratory give fish a small does of oil through either their food, water, or the sea floor sediments, then analyze how their bodies recover.
