Philippe Cousteau travels to Plymouth, England, one of Europe’s largest seafood exporters, to explore fisheries and the impacts these practices can have on the environment.  Philippe joins Dr. Martin Atrill from the University of Plymouth out at sea to use a trawl net for a fish survey and to understand how data is collected and fish populations are monitored.  Fish require balanced and healthy ecosystems in order to thrive and feed our growing population.  Philippe joins Dr. Abigail McQuatters-Gollop to learn more about plankton the base of the food web that supports all fish.
