NEBRASKA CRAYFISH COLLECTIONS
As of this writing, I have some 915 crayfish
collections from 776 sites. Of these, 595 or
65% are my own collections. Of the
remainder, 115 were collected during the
2003-2005 statewide stream fishery survey,
98 were collected by my summer aides
during stream sampling, 42 were sent to me
by other NGPC staff, 31 were found in
online museum catalogs, 16 were found in
published reports and 10 came from other
sources. While there were a few crayfish
collections between 1890 and 1980, over
94% were collected after 1993. The map
below illustrates the collection locations
(black dots) as well as sites that were
sampled but no crayfish were found (open
circles). I should note that if I found none at
a site, I moved on and often failed to fill out
a data sheet. Therefore many of the stream
sections in the map with no dots or circles
actually were places where no crayfish were
found.
