How we scored them

The Shelf Score weighs fit for a young reader hunting for fish books, contents and edition, value, and the listed reading age or level where one is given. Three of the five picks list a reading age and a grade level, each reading age marked as from customers; the other two state neither and earn nothing on that part. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best picture books about fish

Match the reading age to the child

The nonfiction picks state reading ages of 3 to 7, 3 to 6 and 2 to 6 years, with grade levels from Preschool to grade 4. Each reading age is marked as from customers, so check the description too. For the wider ocean, see the ocean picture books list.

Choose facts or a story

Three picks are nonfiction about how fish breathe and what odd fish do to survive. The Rainbow Fish is the story pick, and the ocean book covers the wider sea. Animal fans may also like the pet picture books list.

Check pages and format

Listings here run from a 14-page board book to the 48-page Wish for a Fish. The board book suits babies, while the 48-page pick gives an early elementary reader more to explore.

Before you buy

• Confirm format and page count: Wish for a Fish is 48 pages; the Rainbow Fish board book is 14.
• Match the grade level to the child: stated levels run Preschool to 1, Preschool to 3, and Kindergarten to 4.
• For the two picks with no stated reading age, pages or date, read the description and check a sample page first.
