Whales are mammals ; see relevant link for additional information .
Whales have pelvic bones because millions of years ago, they were land animals, but as they evolved, they no longer needed their pelvis because over time they lost their need for legs. So now their pelvis and legs are vestigial, meaning they no longer serve their original purpose. They just kept the trait. As for fish, they never had legs, so no need for a pelvis.

How does the pelvic girdle size of fish compare to those of land animals?
Fish do not have "pelvic girdles" per se. Land animals in large majority have skeletal structures in their hips known as pelvic bones. In humans, men have a narrow pelvic size and women have a wider pelvic size. This is because women bear babies. The circular shape of these pelvic bones are referred to as the "pelvic girdle". Fish, however, don't have hip bones. Living in the water has eliminated the need for the extra physical support those bones would give during pregnancy. Since fish range in size from near-microscopic up to the immense whale shark, the equivalent to the pelvic area would vary greatly in size. Mammals too, range widely in size so comparison is difficult without a more specific question.
