Objectives
Characterize the diet of age 0 largemouth bass in Hillsdale (stocked) and Perry (control) reservoirs using both a quantification of stomach contents and stable isotope analysis.

Determine if early spawned largemouth bass and natural spawned largemouth bass occupy the same areas of Hillsdale Reservoir and assess habitat utilization by largemouth bass and vertebrate and invertebrate prey species across seasons at both reservoirs.

Determine if early spawned largemouth bass are larger than natural spawned largemouth bass by the end of their growing season and assess seasonal changes.

Utilize novel techniques (e.g., RNA:DNA) to identify diet-growth related differences between early spawned largemouth bass and natural spawned largemouth bass.

Progress and Results
For the 2014 field season, researchers will collect data from lakes on habitat distribution, largemouth bass size, isotopes, diets, and available prey through an every other week sampling regime for each lake. Samples will be collected utilizing techniques identified in the previously approved research plan.
