A student estimates the size of a fish population in a small pond using mark-recapture. On day 1, 80 fish are captured, marked with a fin clip, and released. On day 7, 100 fish are captured; 16 of these are marked. The student uses the Lincoln-Petersen estimator: N = (M x C) / R.
What is the estimated population size?

500
- B
16
- C
1000
- D
200
Explanation
N = (M x C) / R = (80 x 100) / 16 = 8000 / 16 = 500 fish.
