LengthFrequency Analysis Wizard (Potamotrygon leopoldi) (Designed by Rainer Froese in 2004) Step 1: Introduction 
Internet Explorer is tested to work for the LF Wizard. FishBase 
In the following you will be guided through an analysis of
lengthfrequency data, resulting in an estimation of the degree of
exploitation, and an indication of how much more could be caught with a
different fishing strategy.
For advanced users we also provide an approach to estimate Linf, Z/K, Z,
annual reproductive rate (alpha), intrinsic rate of population increase
(rmax), population doubling time (td), and fishing mortality associated with maximum
sustainable yield (Fmsy).
