Introduction
• Bridgestone/Firestone Wildlife Management Area
• Two ponds (2.5 hectares)
• Pond 2 population appears stunted (Simpson 2004)

Objective/Hypothesis Statement
• The objective of the research is to determine if the largemouth bass population in pond 2 is less healthy than the population in Pond 1.
• Hypothesis-The largemouth bass populations in Pond 1 will have higher relative weights than the population in Pond 2.

Methods and Materials2 minutes
• 10 minute sample with Electro-fishing boat• Accu-weigh scale and Wildcoe measuring board • Use lengths and weights to determine relative
weight for each fish (condition of fish/certain water body/regional standards)
• Plot the relative weights on a graph to determine the overall condition of the fish populations
-Over 100-problem with surplus prey -Under 100-problem with forage shortage -Near 100-good condition

Results
• Pond 2- low relative weights
• Pond 1- good relative weights

Discussion
• Pond 1-fertilized fields=increased biomass
• Pond 2-no fertilized fields=decreased biomass (clear water)
• Possible solutions:
1. Fertilize and Lime (phytoplankton growth)
2. Rotate Free Fishing Day between ponds
