Whether readers have ever gone fishing or not, they will be "hooked" by the interesting information in Salmon: A Link in the Food Chain. Using salmon as a way to show the interconnectedness of the food web, the author explains how a tiny salmon egg needs food, and later as an adult, becomes food. The theme throughout the book is the delicate balance of nature and the need for maintaining it. Photographs provide visuals of unfamiliar concepts and vocabulary.
