) A student, for want of something better to do, decided to go fishing in the NCBS pond. She caught 50 mosquito fish, but rather than take them home for dinner (they were too small anyway) she decided to just mark them and return them to the pond. A week later she went fishing again. This time she caught 40 mosquito fish, of which 5 were marked. Based on these data, what is the estimated size of the mosquito fish population in the pond?

  1. 50 fish and all marked.
    40 fish and 5 marks found. so you found 5 of 50 or 1/10. So you should have how many total fish in the pond as an estimate.
