Look at R for this sort of thing, I know several fisheries modellers using R for kernel density analyses. R/PostGIS/GRASS/QGIS/mapserver (with Proj.4, GDAL, GEOS, etc...) all work pretty well together to support such work as an Open Source suite. See: http://www.stat.math.ethz.ch/R-manual/R-devel/library/stats/html/density.html For a more general list of R functions, http://www.oulu.fi/atkk/tkpalv/unix/R/library/stats/html/00Index.html and for general R spatial packages/info, http://r-spatial.sourceforge.net/ Hope this helps....
