A sportfish is a fish that people catch for fun, not for food.
Sportfishing can make people think of relaxing, being outside, and spending time with friends or family.
Examples:
Dad caught a big sportfish on our fishing trip.
We went to the lake to catch sportfish.
The sportfish was too small, so we let it go.
I caught a sportfish THIS big!
In the story, the sportfish was as big as a boat.
We always catch sportfish when we go fishing.
