Figure 10. Two propagation cages placed in Lake Pepin (Pool 4) in June 2000. Zebra mussels are shown attached to the inside of the wooden cage in the top photos; one subadult black sandshell (Ligumia recta) was found in June, 2001. The middle and bottom photos show installation of a metal frame and subsequent monitoring. The cage filled with sediments and was difficult to monitor; three subadult Higgins’ eye pearlymussels (Lampsilis higginsii) were collected in June 2001.
