Question

There are a total of 8 ponds that are all the same size located in the Rocky Mountains of Colorado.A

scientist looking at the Trout population in this area used a mark and recapture method to estimate the
population in one of the ponds. They originally marked 34 Trout and then came back to the same pond a few
days later and caught 60 Trout. Of the 60 Trout 19 of them had the marking on them. Using this information,
estimate the total amount of Trout there are in all 8 ponds in the Rocky Mountains.

Answer 1

The estimated total Trout population in all 8 ponds in the Rocky Mountains is 34 times the population of the pond where the study was conducted. Therefore, the estimate is 34×8=272 Trout.
