The grouper is about 50 pounds heavier than the tuna.

The key word in this question is "about".

We could find the difference using the exact weights,but in an informal conversation we generally round off to easy values.

The tuna weighed about 390 pounds and the grouper about 440 pounds.

The difference is 440-390 = 50 pounds

The grouper is about 50 pounds heavier than the tuna.
