• Assess water supply management options for northeastern Illinois

• To test the hypothesis that human and animal E. coli strains are distinguishable
• To screen and select appropriate primers
• To build a small RAPD (random amplied polymorphic DNA) fingerprint database for E. coli from human and nonhuman sources
• To identify landmark DNA patterns
• To determine the sensitivity and applicability of this technology

• Examine diets of sympatric and allopatric populations of mottled sculpins and round gobies
• Determine the relationship between mottled sculpin and round goby feeding on benthic invertebrate
  communities
• Assess the role of round gobies as trophic replacements for mottled sculpins

• Determine whether ruffe and gobies display overlap in use of habitat and food and thus may compete for benthic resources
• Determine whether zebra mussels will modify ruffe – goby interactions directly by serving as a major food resource for gobies or indirectly by increasing benthic heterogeneity and associated invertebrate production,
• Determine how yellow perch will respond to coexistence with ruffe and gobies in the presence or absence of zebra mussels

To evaluate the effect of culture temperature on growth, survival, and body composition of largemouth bass.

• Obtain the full-length perch growth hormone (GH) cDNA.
• Clone and express the yellow perch GH mRNA in a protein expression system.
• Assay the recombinant perch GH for growth promoting activity in juvenile perch.
• Produce antibodies to the recombinant perch GH.
