Added an extra zero too all three of the different types of fish because there's an estimated 5,000. Added them up and came close to 5,000. And there's a logical answer that would fit with the way I did this.

Estimation.

OpenStudy (dmezzullo):
No, just add an extra zero to the number up in the question and there's your answer. It's one of the multiple choice answers.
