Removal Sampling

 

For more information visit our website here.

 

Removal Sampling allows you to calculate the statistics from removal trapping experiments. It contains three easy to use methods: constant & variable probability of capture (Zippin's maximum likelihood, ML) and a regression model.

 

Using the ML methods the program can calculate a population estimate, the upper & lower 95% confidence intervals & the probability of fit of the model.

 

The program allows instantaneous graphical comparison of the various methods & rapid sub-division of the data. Data from spreadsheets such as Excel can be imported as CSV files.

 

Removal Sampling is particularly useful for:

1.The estimation of fish densities using data collected by electric fishing:
2.Small mammal population estimation using traps.
3.Studies on insects that live in small, discrete populations that can be sampled using techniques such as sweep netting or pitfall traps.
