2. Objectives
Obtain an estimate of zooplankton diversity and abundance in Sisodiya Pond
Determine if Sisodiya pond could support a population of koi

10. Plankton Net Results

11. Ekman Sampler Results

12. Plankton Net Sample Calanoids: ~10.88 ind./L Cyclopoids: ~ 1.94 ind./L
Diaphanosma: ~ 0.06 ind./L
Ceriodaphnia: ~ 0.14 ind./L
Chaoborus: ~0.035 ind./L

13. Ekman Samples Chaoborus: ~22 ind./Sample Chrominids: ~ 27 ind./Sample
Oligochaete: ~29 ind./Sample

14. Specimens from your pond!
Chaoborus
Calanoids

15. Interpretation Macroinvertebrates Fish Community Red Side Shiner
Speckled Dace
Visibility/Turbidity
Secchi Depth = 5.08 cm

16. Suggested Improvements
Riparian Vegetation
Willows
Waterfowl Limiting
In-Water Habitat
Artificial Fish Structure

17. Riparian Vegetation Near Bank vegetation Waterfowl Reduction
Increase Insect Productivity
Bank Stabilization
Ag. Runoff Reduction

18. In-Water Habitat Predation Protection Artificial Koi Viewing
Great Blue Heron
Minks
Artificial
Long lasting
Koi Proof
Koi Viewing

19. Conclusion
Sisodiya pond could support a small population of koi with supplemental feeding
Improvements would be needed
May not be able to see fish due to turbidity
