Question
Which of the following is most suitable to estimate the population of Tilapia fish in a pond? a. Quadrat b. Transect c. Direct counting d. Capture-recapture
Correct Answer
Option D is the correct answer.
Detailed Explanation
For mobile animals like fish in a pond, the capture-recapture (or mark-recapture) method is most suitable. A sample is captured, marked, released, and then a second sample is captured. The proportion of marked individuals in the second sample allows for an estimate of the total population.
Hint
This method involves marking a sample, releasing them, and then seeing how many are recaptured later.
