We have some records
that go back to the late 1800s.Most
of which are stockings of all kinds of fish by the US Fish Commission as food
fish.We attempt to georeference the
records to the smallest possible scale such as a point if we are lucky to get
that kind of accuracy.The next level
we use is a Hydrologic Unit based on an 8 digit code.Here you can see the US broken into these
units.Up close this is what Michigan
looks like broken into these Hydrologic Units. Over the last few years we
have added about 30 new species most of which are marine and we have a lot
more to add I believe based on the number of survey that are being conducted
by various groups of scientists.In
all, we have recorded approximately 1100 aquatic species.
