Ekman Sampler Results
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
Ekman Samples Chaoborus: ~22 ind./Sample Chrominids: ~ 27 ind./Sample Oligochaete: ~29 ind./Sample
Specimens from your pond! Chaoborus Calanoids
Interpretation Macroinvertebrates Fish Community Red Side Shiner Speckled Dace Visibility/Turbidity Secchi Depth = 5.08 cm http://www2.dnr.cornell.edu/cek7/nyfish/Cyprinidae/redside_dace.html https://www.nysm.nysed.gov/exhibits/longterm/fon/fon2006/index.html
Suggested Improvements Riparian Vegetation Willows Waterfowl Limiting In-Water Habitat Artificial Fish Structure
Riparian Vegetation Near Bank vegetation Waterfowl Reduction Increase Insect Productivity Bank Stabilization Ag. Runoff Reduction http://www.naturalheritage.state.pa.us/community.aspx?=30022
In-Water Habitat Predation Protection Artificial Koi Viewing Great Blue Heron Minks Artificial Long lasting Koi Proof Koi Viewing http://www.pondking.com/product-category/artificial-fish-habitat/
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
