354

Step-by-step explanation:

We have the following formula:

actual population / captured population = tagged population / tagged population captured.

We have the following dа ta:

captured population = 177

tagged population = 26

tagged captured population = 13

Replacing:

real population / 177 = 26/13

solving:

real population = 177 * 2 = 354

In other words, there are a total of 354 fish.
