A Review of the Interactions between Catfi shes and Freshwater Mollusks in North America

Abstract: Catfi shes are important in freshwater ecosystems not only as consumers, but also as essential partners in symbiotic relationships with other organisms. Freshwater mol- lusks are among the many organisms that have interactions with catfi shes. For example, icta- lurids are hosts for larvae of several native freshwater mussel species. The larvae, which attach briefl y to gills or fi ns of fi sh to complete their development to the free-living juvenile stage, disperse via upstream and downstream movement of host fi sh. In turn, freshwater mussels serve as a food source for some catfi sh species while other catfi sh species may use spent mus- sel shells for habitat. Ictalurids also benefi t from the conservation status of many freshwater mussel species. Federal and state laws protecting these invertebrates can preserve water qual- ity and habitat and, at times, provide incentives and funding for conservation and restoration of stream and riparian habitats.

Status, distribution, and habitat preferences of the stripetail darter, Etheostoma kennicotti and spottail darter Etheostoma squamiceps in the Shawnee National Forest, Illinois

Abstract: In Illinois, the stripetail darter Etheostoma kennicotti and spottail darter Etheostoma squamiceps are restricted to tributaries of the Ohio River. Because of their narrow ranges, we examined the status, distribution, and habitat preferences of E. kennicotti and E. squamiceps in streams in the Shawnee National Forest, Illinois, during June 2009 to determine whether these species warrant listing under the Illinois Endangered Species Protection Act. These two fishes were the most abundant darters found and were commonly collected under slab rock and occurred in multiple basins throughout the Shawnee National Forest. Because of its high abundance and occurrence in multiple basins, we feel that neither E. kennicotti nor E. squamiceps warrant listing at this time.
