This nonfiction book introduces salmon to young readers. The book discusses what salmon are and the different stages of their life. This book is written simply enough to engage young readers. I feel it gives just the right amount of information. The book teaches students that salmon can live in salt and freshwater and about their stages of life. It introduces terms such as alvien (the babies that grow in the eggs), fry (the next stage in which they grow teeth, skin and begin to hunt for insects) and smolt (the stage right before adult when their bodies are becoming adjusted to being in salt and freshwater). The book has wonderful photographs to accompany the text. There is also a glossary, learn more and index at the end of the book.
