FishBase on the Web offers a free "relational database with information to cater to different professionals such as research scientists, fisheries managers, zoologists and many more." Developed at the International Center for Living Aquatic Resources Management together with the Food and Agriculture Organization of the United Nations and many other partners, FishBase is the online source for "all you ever wanted to know about fishes." This multi-featured Web site is frequently updated. Recent additions include a Life History Tool for calculating whole-body nitrogen and crude protein 115 content from wet weight and a new mapping tool that "allows zooming, point identification, different environmental layers, environmental boundaries and environmental forcasting [sic] for FishBase point data." Other features of this extensive Web site are too numerous to list.
