Hosted by the University of British Columbia, this website contains Fish On Line, a draft guide for teaching and learning about ichthyology. The "guide provides a structure and case study material for a computer-based course in ichthyology for upper undergraduates and graduate students in biology or environmental science. The key resource made accessible through this guide is FishBase, a large database on the biology of fish, available on CD-ROM (for Windows operating system) and on the Internet (www.fishbase.org/search.cfm)." The site provides brief introductory sections to the field of ichthyology and to FishBase, as well as chapters on Evolution, Morphology, Reproduction, and more. The site also offers supplementary exercises accompanying each chapter, and an extensive list of related links.
