Removal Problems with Program Mark and Capture

[joaquim]

I tried to run Program Mark with a removal example: http://www.cnr.colostate.edu/class_info ... xer-16.pdf.
The objective of this exercise is to estimate the abundance of brook trout in two stream reaches of Colorado Creek.

First I chose "closed captures" in "select data type" and second I fixed the recapture parameter (c) to zero. Then I ran the model and the program show a parameters list like: Model, AICc, Delta AICc,... I just obtain Mt+1 but no estimated N.


How can I obtain the estimated values (p and N)???


I also tried to estimate these values with Program CAPTURE to fit the usual zippin formulae (constant catchability), but I obtain: Losses on capture will be excluded from the data in running Program CAPTURE.
Perhaps I need another data format???


Can anybody help me?
Thanks!
