A number of Ecopath PowerPoint presentations are now available through this web. They are neither polished nor rounded off, and will be updated from time to time. If you are to make presentations of the Ecopath system you are welcome to use these presentations, please keep us posted though, as we try to track the use of Ecopath.
The files are pretty big, and have been zipped. You will need to unzip them, and to view them using Microsoft PowerPoint
