Question 1041655:  9. The Capture/Recapture method:  A biologist wants to estimate how many fish are in a small pond.   
Her team captures 600 fish, tags all of them, and places all of them back in the pond.   
A week later, her team captures 150 fish, of which 30 are tagged. 
Calculate an estimate of the N-Value of the fish population in the pond:
 
 
 
 
					       estimated N-Value (population size) ______________

You can  put this solution on YOUR website!  The Capture/Recapture method: A biologist wants to estimate how many fish are in a small pond.  
Her team captures 600 fish, tags all of them, and places all of them back in the pond.  
A week later, her team captures 150 fish, of which 30 are tagged. 
Calculate an estimate of the N-Value of the fish population in the pond:  
---- 
population/caught = caught including tagged/tagged caught 
N/600 = 150/30 
N = 600*5 
N = 3000
