What has been stocked to date?
The first higginsii inoculated fish stocking of the Iowa River was
conducted in the fall of 2001. A total of six fish stockings have
taken place, four spring stockings (2002-2005) and two fall stockings
(2001 and 2003). A total of 5,970 inoculated fish have been stocked.
Fish species stocked are mostly smallmouth bass and walleye.
The first stocking of the Cedar River was conducted in the spring of
2001 and it has been stocked each spring up to 2005. A total of 5,181 higginsii inoculated fish have been stocked into the Cedar River system.
This Sampling Effort:
If any young higginsii have survived we expect the size to range in
size from dime-sized to three or four inches. We plan on utilizing
several techniques to sample for these mussels. The effort will consist of basic pollywoggin (wading), diving, brailing and sieving sediment.
You do not have to be a mussel expert to do this sampling. Experts from the US Fish and Wildlife, Corps of Engineers and Iowa DNR will be on
hand to help with sampling efforts. The Iowa DNR will have boats on
site to shuttle people if needed.
Sampling will start on the Iowa River because a number of live species of mussels were found near Hills. It is hoped that our transformed
mussels will inhabit this location as well. We will organize the event
on Monday at 10:30.
What to bring:
Stream wading shoes and cloths
Gloves (some will be provided)
Life jacket (some will be provided)
Warning: Both of these Rivers contain dangerous items in the water
and sediment such as broken glass and rusty wire. Always be cognizant
of these hazards and dress accordingly. Trash bags will be available
and do plan on leaving these rivers cleaner then when we found them.
