Question
A researcher wanted to know how many fish were in a dam.He caught 20 fish and marked them by clipping out a small section of their tail fins.He then released them back into dam.A few days later he caught 25 fish and found that 8 had been marked
1.estimate the total number of fish in the dam by using the formular P=FxS/M
Give one reason why the method used by the researcher to mark the fish could have resulted in an inaccurate estimate of the fish population in the dam.
Thanks
