Length-Frequency Analysis Wizard (Helcogramma desa)
(Designed by Rainer Froese in 2004)
Step 1: Introduction
Internet Explorer is tested to work for the L-F Wizard.
In the following you will be guided through an analysis of
length-frequency 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).
